Key Benefits

  • An efficient flame retardant in styrenic polymers
  • Well used in bio-polymers (PLA) and Polyolefins such as LLDPE for DIN-4102 B2; PP foams, FMVSS302; non-woven NFPA-701 in textile applications.
  • Because it is a melting solid (MR ~ 105°-108°C), offers processing advantages over other non-halogen additives currently offered for the same application
