KRATON® D1184 ASM is an asymmetric (branched) styrene-butadiene block copolymer (SBS) produced by Kraton Corporation. Grade designation: D — diene (butadiene)-based SBS series, 1184 — internal formulation index, ASM — Asymmetric (a branched molecular architecture with radial, star-shaped chains, as opposed to the linear D series).

The styrene content of 30 wt % is a medium concentration that provides a balance of strength and elasticity. The branched architecture gives D1184 ASM three critically important properties that set it apart from linear SBS: 1) low melt viscosity at standard processing temperatures — easier hot-melt processing and adhesive application; 2) high cohesive strength — the adhesive does not flow under load; 3) retention of elasticity over a wide temperature range.

Supplied as a powder dusted with amorphous silica (anti-block agent) to prevent caking during storage and transport. This is a distinctive feature of D1184 ASM compared with pelletized SBS grades, which are more convenient for pellet feeding of extruders but less effective for direct hot-melt compounding.

Typical parameters: polystyrene content 30 wt %, MFR ~5–10 g/10 min (200 °C / 5 kg), Mooney viscosity ML(1+4) 100 °C ≈ 50, Shore A hardness ~65–75, tensile strength 25–30 MPa, elongation at break 700–900 %, compression set 30–40 % at 70 °C / 22 h. Density 0.94 g/cm³.

Key advantages

• Low melt viscosity — easier hot-melt processing, lower compounding energy consumption
• High cohesive strength combined with high adhesion — an ideal balance for PSA (pressure-sensitive adhesives)
• Branched architecture — better hot-melt stability compared with linear SBS
• Good solubility in hydrocarbon solvents (toluene, cyclohexane) — for solvent-based adhesives
• Compatibility with hydrocarbon resins and paraffins for tackifier formulation
• Elasticity down to −40 °C — suitable for cold climates
• Standard styrene content of 30 % — a balance of strength and elasticity (for higher adhesion — D-series grades with 15-20% styrene, for higher strength — 40 %)
• Powder form with anti-block — easy dosing into compounding equipment

Applications

• Hot-melt adhesives (HMA): industrial hot-melt adhesives for packaging, carton converting, furniture edging and lamination — the main market for D1184 ASM
• Pressure-sensitive adhesives (PSA): hot-melt adhesives for self-adhesive labels, tapes, medical plasters and hygiene products (diapers, feminine hygiene)
• Adhesives for hygiene products: construction and elastic adhesives in the manufacture of diapers and sanitary pads — bonding nonwovens, elastic strips, tampons
• Construction adhesives and sealants: assembly adhesives based on hydrocarbon resins, silicone and SBS sealants
• Bitumen modifier (PMB): addition of 3–5 % to bitumen to improve the elastic-plastic properties of asphalt concrete and extend the service temperature range of road pavements (polymer-modified bitumen)
• Roofing mastics and membranes: bituminous roofing materials with improved elasticity and crack resistance
• Shoe soles: compounding with other SBS / SBR / extender oils for the production of soles for sports and casual footwear
• Plastics modifier: impact modifier for PS and PP at 5–15 % loading — increases impact strength, especially at low temperatures

Limitations

• SBS is an unsaturated elastomer; not for long-term outdoor service under UV exposure without UV stabilization (for outdoor use — hydrogenated SEBS grades, e.g. the Kraton G series)
• Sensitivity to ozone — cracking of surface layers at ozone concentrations >0.1 ppm
• Not for contact with aromatic solvents (dissolves in toluene and xylene)
• Not for continuous high-temperature service above 80 °C (Tg of the polystyrene blocks is ~95 °C — cohesive strength is lost above this)

Elvaloy® PTW is a reactive terpolymer of ethylene, n-butyl acrylate and glycidyl methacrylate (E/n-BA/GMA) developed by DuPont (now Dow) specifically as a reactive impact modifier for engineering polymers with ester or amide functionality: PA (polyamides), PBT (polybutylene terephthalate) and PET (polyethylene terephthalate). The PTW designation stands for Polymer Toughener with Worldwide approval (international certification for food contact).

Key feature: the epoxy group of the glycidyl methacrylate unit (~8 wt % GMA) reacts chemically with the end groups of PA (-NH₂, -COOH) or the ester linkages of PBT/PET during compounding at 250–280 °C. This creates a grafted copolymer interphase between the matrix and the elastomer phase, improving adhesion and dispersion — considerably more effective than mechanical blending with a non-reactive elastomer (EPDM, SEBS).

Effect on the final matrix: +200–500 % impact strength at 10–20 % Elvaloy® PTW loading in PA, PBT or PET with minimal loss of stiffness (vs non-reactive modifiers, where the stiffness loss is 30–50 %). This has made Elvaloy® PTW the industry standard for super-tough polyamide and PBT grades.

Typical parameters: GMA content ~8 wt %, n-butyl acrylate content ~28 %, ethylene ~64 %, MFR ~12 g/10 min (190 °C / 2.16 kg), density 0.94 g/cm³, melting temperature Tm ~70 °C, Vicat softening temperature 47 °C, Shore A hardness ~85, elongation at break >500 %.

Key advantages

• Reactive impact modification of PA/PBT/PET — the only modifier class that grafts chemically onto the matrix end groups (vs mechanical blending)
• +200–500 % impact strength at 10–20 % loading — typical reinforcement for super-tough grades (PA66 + 15% PTW = notched impact strength of 80–120 kJ/m² vs ~5–6 for unmodified PA66)
• Minimal loss of stiffness compared with non-reactive modifiers thanks to interfacial adhesion
• Good resistance to hydrolysis and heat ageing — critical for PBT/PET applications
• FDA / EU 10/2011 compliance for food contact (PTW = Worldwide approval)
• Suitable for recycled PET — Elvaloy® PTW restores the molecular chain length of degraded rPET through epoxy coupling
• Stability at high compounding temperatures (250–290 °C) — does not scorch in the screw
• Flexible dosing — from 2 % (umbrella-effect tackifier) to 25 % (super-tough)

Applications

• Super-tough polyamides (PA6, PA66, PA610): compounds with non-break unnotched impact strength (>200 kJ/m²) — for airbag clips, snap-fit hardware and fasteners with critical impact loads at −40…+80 °C
• Impact modification of PBT: for automotive connectors, electric-vehicle charging systems and consumer electronics — higher impact strength without loss of dielectric properties
• PET bottle-grade upgrading: adding 1–3 % Elvaloy® PTW to bottle-grade PET for cold climates (winter retail at −20 °C) — reduced brittleness
• Compatibilizer for PA/PE blends: a bridge between incompatible PA and PE matrices for hybrid multilayer packaging and technical compounds
• Recycled PET / rPET upgrading: restoring the intrinsic viscosity of degraded rPET — moving from mechanical to reactive recycling
• Road construction and roofing mastics: bitumen modifier with improved adhesion to mineral aggregates
• Hot-melt adhesives for thermoplastics: connection-bridge adhesive between an EVA matrix and PA/PET films

Limitations

• The reactivity with PA/PBT/PET is a feature, but it also requires precise control of the compounding temperature (250–280 °C; higher — GMA degradation, lower — insufficient grafting)
• Incompatible with matrices without active functional groups (PE, PP) unless an additional compatibilizer is used
• Price is 3–5 times higher than non-reactive impact modifiers (EPDM, SBS, SEBS) — justified only for critical super-tough applications
• The epoxy function is moisture-sensitive — the matrix must be dried before compounding

Global market counterparts: Arkema Lotader® AX8840 (E/MA/GMA), SK Functional Polymer Bondyram® 7103 (E/BA/GMA), Mitsubishi Modiper® A4400 (E/GMA), BASF Joncryl® ADR (GMA-based chain extenders, a narrower niche). Elvaloy® PTW is the original DuPont / Dow grade with the longest application history and the most accessible technical support.

Glass Fiber for reinforcing polymer compounds and composites from Material Wizard — a wide range of glass types (E-glass, S-glass, ECR-glass), geometries (chopped 3–4.5 mm, long-fiber 10–12 mm, roving for pultrusion, milled fiber 0.2 mm) and sizings adapted to the specific polymer matrix type (PA, PBT, PC, PP, epoxy, vinyl ester). The base reinforcing filler for all GF-grade compounds in the MW catalog: Examid PA66 GF30/GF50, Exablend PBT GF30-W3201, PC GF30-930, Ultraplen PP GF30-530 and dozens of others.

Glass types — selected for the service environment

• E-glass (alumino-borosilicate) — the standard, 85 % of the global market. Fiber tensile strength ~3500 MPa, modulus ~73 GPa. Universal for PA/PBT/PP/PC.
• ECR-glass (E-Corrosion Resistant) — boron-free, improved resistance to acids, alkalis and seawater. For the chemical industry, offshore and agro applications.
• S-glass / R-glass / T-glass — high-strength (tensile ~4700 MPa, modulus ~86 GPa), for aerospace, ballistic protection and high-end composites. 3–5 times more expensive than E-glass.
• C-glass (chemical) — for chemical resistance in acidic environments (no alkalis)
• AR-glass (alkali-resistant) — for reinforcing cement composites (GFRC)

Geometry and supply form

• Chopped strands (chopped fiber): length 3.0, 4.5, 6.0 mm; for compounding with thermoplastics on a twin-screw extruder. After processing, the actual fiber length in the part is 0.2–0.4 mm.
• Long-fiber pellets (LFT-G): 10–12 mm pellets in which the fiber runs the full length of the granule. After molding, the fiber in the part is 3–8 mm long, providing substantially better impact and creep performance.
• Direct roving (assembled/single): 600–4800 tex, for pultrusion, filament winding and weaving into fabrics (woven roving).
• Milled fiber: 0.1–0.2 mm length, for thin-walled parts and SMC/BMC compounds.
• Chopped strand mat (CSM): for hand lay-up and contact molding.
• Continuous filament mat (CFM): for continuous molding.

Sizing — critical for adhesion to the matrix

Sizing is an ultra-thin polymer layer on the fiber surface that ensures compatibility with the specific polymer matrix and protects against abrasion. Without the correct sizing, a GF-grade compound loses 30–50 % of its mechanical properties.

• Aminosilane sizing — for PA6, PA66 (interacts with -NH₂ and -COOH end groups)
• Epoxy-compatible sizing — for epoxy composites and PC
• Polyester-compatible sizing — for PBT, PET
• Vinyl-ester / unsaturated polyester sizing — for GFRP composites
• Multi-compatible sizing — universal grades compatible with different matrices
