Performance PIN masterbatch for PE foams

Tosaf launches new phosphorus flame retardant for polyethylene foams for insulation, packaging, construction. The new non-halogenated PIN FR is effective at 10 – 15% loading and acts by a phosphorus gas-phase mechanism, inhibiting burning by blocking free radicals. It offers effective dispersion in foam and does not impact foam nucleation or cross-linking, so preserving mechanical and thermal insulation properties, and can be used in both crosslinked and non-crosslinked foams. Polyethylene foams offer corrosion resistance, dimensional stability, and thermal insulation and are increasingly used in acoustic and mechanical dampers, pipe insulation, flooring, and transport packaging. Because the foam is highly flammable, flame retardants are necessary to respect fire safety requirements in construction, shipping, buildings, or other applications. The new PIN masterbatch can achieve this without using halogenated chemicals. Tosaf is a leading developer and manufacturer of additives, compounds, and colour masterbatches for the plastics industry (see interview in pinfa Newsletter n°144).
