Ampacet now offers halogen-free flame retardant masterbatches, HALOFREE 709 and HALOFREE 229, featuring flame retardancy in polyethylene film at low addition rates and compliance with health and environmental safety protection regulations.

The company says that its new masterbatches provide “excellent optics and film clarity”, and that they can be coloured with masterbatches from Ampacet’s colour portfolio.

Ampacet HALOFREE 709 is rated “excellent” in flammability testing classifications including B2 (DIN4102), VTM0 (UL94), and Euroclass close equivalents. Meanwhile, Ampacet HALOFREE 229 has achieved flammability testing classifications including M1 (NFP 92-503).

Both masterbatches comply with human health and safety protection regulations including ISO14001 and OHSAS 18001 requirements for risk optimization, environment legislation such as 94/62/EC (European Packaging and Packaging Waste directive) and ROHS; REACH and automotive norm VDA 232-101 (Global Automotive Declarable Substance List).

Flame retardancy for plastics is designed to provide self-extinguishing characteristics, prevent plastic from dripping when it comes into contact with flames, reduce the spread of flames, and decrease the possibility of smoke formation. Conventional flame-retardant agents containing bromine and antimony are, the company says, toxic to the environment and hazardous to the health of humans and living organisms when products burn or are recycled.

Regarding potential applications, Ampacet says: “HALOFREE 709 and HALOFREE 229 are suited for use in a broad range of flexible applications, including carpet backing, industrial packaging materials, ceiling insulation, and under-roof liners for homes, railway stations, and stadiums.”
