PE 1000 ATEX

UHMW-PE – Ultra-high-molecular-weight polyethylene

PE 1000 ATEX

PE 1000 ATEX is an ultra-high-molecular-weight polyethylene (approx. 9.2 million g/mol). The material is specifically designed for applications that require ATEX certification, making it suitable for use in equipment installed in an environment with an explosive atmosphere. PE 1000 ATEX has been approved by TÜV Nord (test record no. YEX 550794). We deliver PE 1000 ATEX as sheets and rods.
