PP-EL

PP – Polypropylene

PP-EL

PP-EL is a polypropylene designed for environments with an explosive atmosphere, with a fire rating of UL94 V-0 (when the material has a thickness of over 4 mm). The material is suitable for welding and a dedicated welding wire is available for it. We deliver PP-EL as plastic sheets, hollow rods and rods.
