Ultraplen® PP V2-600 — self-extinguishing polypropylene UL 94 V-2

Description

Ultraplen® 600 — a self-extinguishing UL 94 V-2 class polypropylene from Material Wizard. An injection-molding PP compound with a highly effective flame-retardant system and an optimized antioxidant package for long-term heat resistance. Intended for parts requiring flammability class V-2 at 1.6 mm, low smoke emission and an affordable price — typical segment: electrical enclosures, white goods, low-risk lighting fixtures.

Decoding the flammability rating — what exactly V-2 provides

• UL 94 V-2 = the specimen self-extinguishes within ≤30 s after removal of the flame source; flaming drips capable of igniting the cotton indicator are permitted.
• V-0 vs V-1 vs V-2: V-0 — extinguishing within ≤10 s, no flaming drips; V-1 — ≤30 s, no flaming drips; V-2 — ≤30 s, flaming drips permitted.
• Where V-2 is sufficient: internal parts of electrical appliances without direct contact with ignitable surfaces, socket housings without horizontal load from above, cable organizers in non-combustible risers.
• Where V-2 is not enough — V-0 is required: enclosures in risers containing ignitable materials, parts exposed to direct flame in standardized tests (UL 1694, glow-wire 960 °C), railway applications per EN 45545.

Advantages

• Guaranteed V-2 with a cost-effective formulation — typically 3–4 times cheaper than PA66 V-0
• Low density of 1.05 g/cm³ — lightweight finished parts
• High flowability for filling thin-walled housings of 0.8–1.2 mm
• Can be colored to standard RAL/Pantone shades (subject to compatibility with the FR package)
• Low smoke emission and low combustion toxicity — compliant with IEC 60695-11-10 and IEC 60707
• Stable flame-retardant package performance after 5+ recycling cycles of production offcuts (up to 20 % regrind)

Limitations — honestly

• V-2 only, not V-0. V-0 at 1.6 mm requires either a thick-walled design or a switch to Ultraplen® FR-V0 (made to order), PA6 V-0 or PC FR.
• Flaming drips are permitted — incompatible with applications above ignitable surfaces
• Low heat resistance, HDT/A ~55 °C — not for under-hood spaces, housings with high-power active electronics, or contact with hot surfaces >90 °C
• UV-unstable in the base formulation — a HALS package is added for outdoor use
• Reduced impact strength at sub-zero temperatures — an EPDM cap is required for cold climates
• The FR package increases sensitivity to stress cracking in contact with solvents
• Not for food contact in the base formulation — FR additives rule out certification per EU 10/2011

Target applications

Low-risk electrical engineering: housings for sockets, switches and surface-mounted junction boxes, cable organizers and holders, distribution box housings up to 16 A, low-risk IT rack components.

Home appliances: internal housing components of toasters, kettles (non-working area), fans and lighting fixtures, coffee machine components (with no contact with the hot zone).

Lighting: housings for household and office LED luminaires, diffusers (transparent V-2 grade on request), mounting brackets.

Transport (interior): automotive interior trim with FMVSS 302 requirements, railway interior elements (separate grades are required for EN 45545), interior parts for metro/electric transport with low fire load.

Industrial packaging: pallets and containers for storing electronic components with FR requirements, technical boxes for electrical equipment.
