Endura® PE-203 is a highly-loaded polyethylene concentrate which can be let down with low density or linear low density polyethylene to make a flame-retardant compound suitable for compounding, film and sheet, blow molding, injection molding, or extrusion. Because of its high loading, Endura® PE-203 achieves physical properties comparable to the base resin and modified flammability characteristics with a low letdown ratio and a high level of thermal stability. Endura® PE-203 provides excellent non-blooming and UV resistant properties. Endura® PE-203 contains active brominated flame-retardants with antimony oxide synergist and stabilizers.
