release heat, and dripping,” says Managing Director Amit Paul. “We are trying to functionalise the polyole- fins through additivation to make it char forming. When the material burns, it crosslinks, which manifests as anti-dripping and reduced heat release rate, and typically smoke density is lower.” The Paxymer system activates at more than 400°C. Paxymer’s main focus is on combinations of its


products with nitrogen-phosphorus FRs, but projects are also ongoing involving mineral hydrates. Latest develop- ments include new products in its Series-300 synergistic and Series-700 stand-alone masterbatch series. Two new Series-300 grades were launched during this year that require a low dosage (under 5%). The Series-300 system is also said to show a major improvement in the cold impact properties in compounds compared to existing halogen-free additive systems. New Series-700 grades are said to be more efficient and cheaper than previous products with V-0 typically achieved at 20-25% dosage. Paul says the system is also about 20% cheaper than other HFFR formulations on the market and “delivers similar price performance as DECA-ethane compounds.” Series-700 products


generate low smoke (below 50 Dm according to ISO5659) and low smoke toxicity, with no corrosive bi-products. Phoslite TM technology from Italmatch Chemicals is based on a high purity inorganic metal phosphinate in conjunction with the company’s own synergists. It is available in powder and masterbatch form. Phoslite TM uses different phosphorus and nitrogen compounds for a wide range of thermoplastic applications through what Ugo Zucchelli, Italmatch Global Sales and Technical Assistance Manager, describes as “a kind of combinatorial innovation approach.” Recent examples include new intumescent halogen-


free blends designed to provide polypropylene with a UL94 V-0 rating. “The mechanism of action is much improved compared to previous systems in term of speed of char forming and strength of the char devel- oped under flame, especially in the presence of glass fibres,” Zucchelli says. “These solutions offer benefits in terms of low additive loading, high process stability, resistance to discoloration, very low smoke, no blooming in final items and reduced corrosion during moulding.” Adeka’s ADK STAB FP-2000 series halogen-free
