Promyde® BF840 is an experimental copolyamide with a reduced melting temperature and a high renewable-raw-material content. Bio-based carbon content: 53.3 ± 0.17 % (ASTM D6866-21, method B). The base molecule is derived from plant sources that do not compete with food agriculture (unlike corn-based PLA) — typically sebacic acid from castor oil and other technical bio-components.

Developed specifically for cast and blown film extrusion as a bio-based alternative to standard PA film grades. It combines three parameters critical for film: high transparency (minimal light refraction and haze), a reduced melting temperature (155–160 °C — 60–65 °C lower than a PA6 film grade, which cuts processing energy costs) and a low crystallization rate (low curl and stable film geometry on high-speed lines).

Typical parameters: density ~1.12 g/cm³, melting temperature 155–160 °C (Tm), Tg ≈ 40–50 °C, water absorption ~3.5 % at saturation (significantly lower than PA6 at ~9 %). Oxygen barrier — on the order of 30–60 cm³·µm/(m²·day·bar) at 23 °C / 50 % RH (typical of PA copolymer film), i.e. 200–500 times better than LDPE and 50–100 times better than PP.

Key advantages

• 53 % bio-based carbon (ASTM D6866-21) — a documented reduction of the packaging carbon footprint; a contribution to brand ESG metrics (Scope 3 emissions)
• Does not compete with food agriculture — technical-grade bio feedstock (castor oil, lignocellulose), removing the food-vs-fuel criticism
• High film transparency — visual inspection of the contents, premium packaging appearance
• Low Tm (155–160 °C): lower extrusion energy consumption vs standard PA6 (220 °C), plus the option of co-extrusion with PE/PP on the same line
• O₂ and CO₂ barrier 200–500 times better than PE — extended shelf life for oxidation-sensitive products
• Low crystallization rate — stable blown-film geometry, no curl on cooling
• Suitability for food contact (after appropriate certification of the finished article to FDA / EU 10/2011)
• Compatible with co-extrusion with PE, PP, EVOH and ionomer for multilayer structures

Limitations and nuances (for engineering planning)

• Experimental status: batch volumes are limited and MOQ and lead time require individual agreement; not for continuous mass production without a prior contract
• The reduced Tm of 155–160 °C limits the heat resistance of the finished film — not for hot filling above 100 °C or retortable packaging
• High gas-barrier potential, but humidity-dependent: above 80 % RH the O₂ barrier drops 3–5 times; for humid environments a multilayer structure with EVOH is recommended
• Base flammability rating is UL 94 V-2 / HB (standard for a PA6 copolymer; not for FR-critical packaging applications requiring V-0)
• Bio-films often require separate compostability certification (EN 13432) — standard Promyde® BF840 is not compostable; bio-based and compostable are different concepts

Applications

• Flexible packaging with brand ESG labeling: packaging for premium food products (meat, cheese, nuts, coffee) where the brand is positioned as sustainability-driven (brands of the Whole Foods / Carrefour Bio class, domestic premium retailers)
• Barrier films for fresh produce: vacuum packaging of meat and cheese, modified atmosphere packaging (MAP) — shelf life extended 2–3 times
• Multilayer co-extruded films: Promyde® BF840 as the intermediate barrier layer in PE/PA/PE and PET/PA/PE structures — for packaging with barrier requirements
• Sterile medical packaging: blisters and thermoformed films for medical devices with bio-based positioning (a 2024–2026 trend)
• Industrial films with ESG labeling: packaging for luxury perfumery, cosmetics and premium electronics, where the packaging is part of the brand promise
• Sustainability-trial pilot projects: for brands testing the transition from PE/PET to bio-based alternatives

Examid® PA12 E-V0 is an extrusion grade of polyamide 12 with a UL 94 V-0 flame-retardant modification (typical halogen-free phosphorus-based FR system, free of bromine and antimony). Designation: E — extrusion grade, V0 — UL 94 V-0.

PA12 is the “lightest” of the engineering polyamides: density 1.01 g/cm³ (1.1–1.3 times lower than PA6/PA66), with water absorption of only ~1.5 % at saturation (6 times lower than PA6, which absorbs ~9 %). This gives a unique combination: dimensional stability in humid environments + hydrolysis resistance in hot water + the best fuel and glycol resistance among polyamides. The PA12 base molecule is synthesized from ω-laurolactam (12 carbon atoms in the chain), which provides high flexibility and a low melting temperature (Tm 178 °C — 40–80 °C below PA6/PA66).

PA12 feedstock can be partially or fully bio-based, depending on the supplier. The original Rilsan® (Arkema) is 100 % bio-based (from castor oil); VESTAMID® (Evonik) is petrochemical-based. Examid® PA12 E-V0 is the MW grade with confirmed V-0 flame retardancy for extrusion applications.

Typical parameters: density 1.01 g/cm³, Tm ≈ 178 °C, HDT/A ~50–55 °C (ISO 75-2, 1.8 MPa), Tg ~50 °C, continuous service temperature ~80–90 °C, water absorption ~1.5 % at saturation (vs PA6 ~9 %), Charpy impact strength retained down to −40 °C without significant loss. UL 94 V-0 at 1.5 mm (IEC 60695-11-10).

Key advantages

• Halogen-free UL 94 V-0 (typically a phosphorus-based FR system) — meets flame-retardancy requirements in electrical engineering, the cable industry and aviation with HF (halogen-free) labeling
• The lowest water absorption among polyamides (~1.5 % vs PA6 ~9 %) — dimensions and mechanical properties remain stable in humid environments, hot water and hydraulic circuits
• The lowest density among engineering polyamides (1.01 g/cm³) — an advantage for weight-sensitive applications (aviation, sports)
• The best resistance among PA to fuels, glycols and hydraulic fluids — the standard material for fuel systems
• UV and weather stabilization — suitable for long-term outdoor service
• Hydrolytic stability in hot water and steam — low degradation even at 100 °C / 1000+ hours
• Impact strength retained down to −40 °C — suitable for arctic and winter applications
• Resistance to ozone, dilute acids and alkalis, aromatic hydrocarbons

Limitations

• Tm 178 °C / HDT/A ~50 °C — not for applications with continuous temperatures above 90 °C; for high-temp use see PA66, PPA, PEEK
• Relatively low stiffness (modulus ~1.4–1.7 GPa) vs PA66 (~2.8 GPa) — consider GF-reinforced grades for structural parts
• Price 1.5–2.5 times higher than PA6 — for a unique property set (density + water resistance + flexibility)
• The FR system raises density by 5–10 % vs unmodified PA12 (typically 1.07–1.10 g/cm³)

Application areas

• Automotive fuel systems: fuel lines, connectors, protective sheathing for gasoline/diesel/E85, reinforced multilayer structures with an EVOH barrier; fasteners, fuel pump housings
• Pneumatic and hydraulic lines: air brake lines for trucks (DIN 74324), compressor lines, medium-pressure hoses
• Cable industry: jacketing of outdoor communication cables and power cables in dry/wet environments, fiber-optic protective tubes, RJ connectors with halogen-free requirements
• Aviation and aerospace: non-structural cabin elements (FAR 25.853), cable jackets for systems with HF requirements, passenger equipment connectors
• Sports equipment: ski boots (the flagship Rilsan application), ski bindings, protective guards, exoskeleton components
• 3D printing (SLS): PA12 is the standard material for selective laser sintering (HP Multi Jet Fusion, EOS PA12) — the V-0 grade opens up functional prototypes with FR requirements
• Electrical hardware: outdoor housings and connectors (solar PV junction box secondary parts, outdoor electric thermostats)

Global equivalents: Arkema Rilsan® AESNO V0 (100 % bio-based from castor oil, the original V-0 PA12), Evonik VESTAMID® L1940 FR, EMS-CHEMIE Grilamid® LV-50H V0, UBE 3030B (Japan). Examid® PA12 E-V0 is the MW grade for halogen-free FR extrusion applications.

Promyde® B33 P2 HI is an extrusion grade of polyamide 6 (PA6) with impact modification and heat stabilization. Grade designation: B — medium-viscosity extrusion/injection grade, 33 — relative viscosity η_rel ≈ 3.3, P2 — second generation of the processing profile (improved processing stability), HI — High Impact (impact modification).

It is developed for parts and products operating under dynamic, impact and cyclic loads with possible temperature rises or contact with aggressive media. Its key niche is extruded products: monofilaments for technical ropes and nets, mechanical-purpose profiles, and medium-pressure hoses with requirements for burst resistance and repeated flexing.

Typical parameters (PA6 HI grade): density ~1.12 g/cm³, notched Charpy impact strength ~12–15 kJ/m² at 23 °C and ~6–8 kJ/m² at −30 °C (ISO 179-1eA — modified PA6 retains low-temperature impact strength twice as well as unmodified PA6), relative viscosity ~3.3, Tm 220 °C, continuous service temperature up to 90 °C (dry). The stiffness reduction after impact modification is ~20–30 % vs standard PA6 (a typical trade-off).

Key advantages

• High impact strength over a wide temperature range — remains serviceable under impact and cyclic loads from −30 °C to +90 °C
• Heat stabilization: resistance to degradation during prolonged extrusion (1000+ hours in the melt zone without significant molecular weight loss), stable monofilament and profile quality in serial production
• Resistance to oils, gasoline, diesel, dilute alkalis and aliphatic hydrocarbons
• Resistance to repeated flexing and abrasive wear — suitable for ropes and cords with a long service cycle
• Can be colored with masterbatches during extrusion
• Processing versatility: extrusion of monofilaments, hoses and profiles; limited injection molding (due to increased melt viscosity)

Limitations

• Stiffness (tensile modulus) 20–30 % lower vs standard PA6 — for rigid structural parts consider Promyde® B33L or GF-reinforced grades
• High water absorption of PA6 (~9 % at saturation) — dimensions and mechanical properties change in humid environments; for marine and outdoor applications with long exposure consider PA610 or PA12
• UL 94 HB / V-2 depending on the batch — not for applications requiring V-0

Applications

• Fishing nets and ropes: monofilaments for trawl and fixed nets, trawl ropes, lashings — long service in salt water and under impact loads against the hull and gear
• Technical cords and ropes: rigging ropes, cords for exercise machines and sports equipment, sailing rigging, cargo lashings
• Industrial monofilaments: brush filaments for road sweepers, card belts, technical filtration meshes
• Extruded hoses and tubing: medium-pressure pneumatic lines (5–10 bar), low-pressure hydraulic hoses, protective tubing for wiring harnesses and optical fiber
• Technical profiles: bumper trims, protective edges of industrial equipment, impact-resistant conveyor system profiles
• Sports and protective gear: elements of hockey uniforms and boxing protection, shoe lacing, protective nets for sports grounds

Promyde® B33L is a medium-viscosity injection molding grade of polyamide 6 (PA6) with an internal lubricant. Grade designation: B — medium-viscosity injection/extrusion grade, 33 — relative viscosity η_rel ≈ 3.3 (96 % H₂SO₄), L — lubricated (internal lubricant to ease part demolding and reduce friction during melt flow).

It is positioned as a universal workhorse PA6 for a broad range of series-produced molded and extruded technical parts: machine building, non-structural automotive components, electrical housings, household appliances. The lubricant shortens the molding cycle time and reduces tooling wear, and also eases the demolding of parts with complex geometry without distortion. Base flammability class UL 94 V-2 (self-extinguishing, but with possible flaming drips) — do not use in FR-critical applications (for V-0, see the dedicated FR grade).

Typical parameters (standard medium-viscosity PA6): density 1.13 g/cm³, η_rel ≈ 3.3, MFR ~12–18 g/10 min (275 °C / 5 kg), HDT/A ~60–75 °C (ISO 75-2, 1.8 MPa; conditioned at 4–5 % H₂O), Tm 220 °C, continuous service temperature ~80 °C (dry), decreasing to ~60 °C at moisture saturation. Water absorption at saturation ~9 % (typical for PA6).

Key advantages

• Processing versatility: injection molding + extrusion from a single compound (simplifies purchasing and warehouse logistics)
• Reduced coefficient of friction thanks to the internal lubricant — easier demolding, longer tooling life
• High impact strength both dry and moisture-conditioned (a typical PA6 characteristic compared with PA66)
• Resistance to oils, gasoline, diesel fuel, dilute alkalis and aliphatic hydrocarbons
• Good electrical insulation properties (dry)
• Can be colored with masterbatches during processing
• Base flammability UL 94 V-2 — self-extinguishing after removal of the flame source
• ISO 9001 compliance at the pellet production stage

Limitations and warnings

• UL 94 V-2, not V-0 — flaming drips of burning material are possible; do not use for parts with FR-critical requirements (electrical equipment requiring V-0/5VA, transport per EN 45545, etc.)
• High water absorption (~9 % at saturation) — parts change dimensions and lose up to 30–40 % of stiffness in service in humid environments; for moisture-resistant applications, consider PA610, PA12 or PPA
• Food contact — the presence of the lubricant requires separate certification of the finished product per FDA / EU 10/2011 (migration testing)
• Gas barrier properties of PA6 are higher than those of PE/PP (on the order of 1 cm³·mm/(m²·day·bar) for O₂) but lower than EVOH and PVDC; multilayer structures or EVOH are needed for high-barrier packaging

Applications

• Molded technical parts: tool housings, medium-load gears, bushings, guides, brackets, fittings for low-pressure pneumatic systems
• Monofilament extrusion: fishing lines, trimmer lines, brush filaments, braided ropes, film monofilaments for textiles
• Extruded profiles: conveyor guides, edge protection, technical profiles for machine building
• Cable industry: technical bushings and sheaths, cable duct components, household extension cords
• Non-structural automotive components: decorative trim, harness holders, interior elements without FR requirements
• Household appliances: attachment housings, handles, internal technical components without food contact
• Construction: fastening elements, bushings in steel structures, non-structural trim

Examid® PA6 R40 is a high-viscosity extrusion grade of polyamide 6. Designation: R40 — relative viscosity η_rel ≈ 4.0 in 96 % H₂SO₄ (significantly higher than standard injection PA6 with η_rel 2.7–3.3). High melt viscosity is critical for processes where the material must hold its shape after leaving the extruder until it fully cools and crystallizes — extrusion of profiles, monofilaments, pipes and sheet, as well as rotational molding (rotomoulding) of large hollow parts.

The high-molecular-weight structure of PA6 R40 provides increased strength, wear resistance and resistance to repeated flexing — the material does not crack under cyclic loading even after long-term service. It is the workhorse for serial production of engineering PA6 semi-finished products in Ukraine and Europe.

Typical parameters: density ~1.13 g/cm³, η_rel ≈ 4.0, MFR <8 g/10 min (low — normal for extrusion), tensile strength 75–80 MPa (dry), tensile modulus 2.8–3.0 GPa, elongation at break 30–80 %, Charpy notched impact strength 4–5 kJ/m² at 23 °C, Tm 220 °C, continuous service temperature up to 90 °C dry. UL 94 V-2 (standard).

Key advantages

• High melt viscosity (η_rel ≈ 4.0) — stable shape retention during extrusion, minimal sagging, stable profile dimensions along the length
• High molecular weight — increased resistance to fatigue deformation, wear and repeated flexing
• High mechanical strength and stiffness — above standard injection-grade PA6 thanks to the longer molecular chain
• Resistance to oils, gasoline, diesel and dilute alkalis
• Good abrasion resistance — for parts with surface contact and wear
• Processable by profile and pipe extrusion, rotomoulding and blow molding
• Basic flame resistance UL 94 V-2 (self-extinguishing)

Limitations

• UL 94 V-2 — not for FR-critical applications
• The high water absorption of PA6 (~9 % at saturation) remains
• High viscosity requires higher processing temperatures and greater screw torque — injection molding requires powerful equipment and is only suitable to a limited extent (for injection, Promyde® B33L or Examid® PA6 NC are better choices)
• Continuous service above 90 °C is not recommended

Applications

• Monofilament extrusion: fishing lines, trimmer lines for garden equipment, brush filaments for industrial sweepers, braided technical ropes
• Profile and pipe extrusion: conveyor guides, technical profiles, protective tubing for harnesses, corrugated pipes, cable sheathing
• Rotational molding (rotomoulding): large hollow products — fuel tanks for special machinery, medium-size technical reservoirs, protective containers
• Blow molding: technical bottles and canisters for aggressive liquids, expansion tanks for cooling systems
• Sports equipment: tool handles and grips, protective guards, fitness equipment elements
• Insulation components: technical sheathing, extruded medium-duty insulators
• Gears and bearings (machined from rod/sheet): stock shapes for machining large gears, bushings and plain bearings
