Durlon® 8400 can be used in process piping and equipment in chemical, pulp and paper, and other general industrial applications. Also, as a unique high-performance compressed sheet Durlon® 8400 is an excellent gasket material for use in steam, mild caustics and acids in Class 150 and 300 service.
Durlon® 8400 contains high temperature phenolic fibres and minerals combined with high-grade nitrile (NBR) rubber. It exhibits higher temperature limits than aramid based materials and the handling and cutting characteristics are greatly improved over carbon and glass fibre products. Durlon® 8400 has a pH application range of 2 to 13 at room temperature, the widest any compressed sheet gasket material produced today.
