Fiber rubber boards - POWERgasket

Asbestos-free sealing plates made of a mixture of aramid fibers with elastomeric binders. They are limited in both temperature and chemical range.

Description

Overview of offered variants

Asbestos-free POWERgasket sealing plates made of a mixture of aramid fibers use elastomers, especially NBR, as binders, and for this reason they are limited in both the temperature and chemical range.
