Jan-Pleun Lens, FRX Polymers, presented the use of the company’s polymeric phosphonate (phosphorus PIN) flame retardants in a range of polymers: PET, epoxy, polyurethane foam and polycarbonate. The products are available as polymers, functionalised oligomers and carbonate co-polymer, for different applications.
Because of their large molecule size, they offer high compatibility with polymer processing, and do not migrate out of finished products. Properties in polycarbonate include high transparency (use in lighting applications), low smoke density and high fire performance in thin films and self-extinguishing with glass fibre reinforced polycarbonate. The company continues to further improve the hydrolytic and heat stability of its products.
