the UL94 Certified PRA794

  • The most popular resin to meet demanding flame-retardancy requirements
  • The PRA794 benefits from UL organisation accreditation as UL 94 V0 recognized material
  • Yellow Card available: E523647
  • Its self-extinguishing capabilities are necessary for most projects with an aero-spatial or electronic background and in public transportation
  • Low aggressive isocyanate leads to extended life of the silicone moulds
