BELPA® CSA-90
Compresses sheets manufactured with
aramide and high quality mineral fibers mixed in a rubber NBR matrix.
This material has got high compressibility, good tensile strength and
low gas permeability, excellent characteristics for many industrial
services, where the high demand of resistance to temperature and pressure
must be combined.
Material with excellent resistance to oils, hidrocarbons, alkalis and
steam in moderate pressures. The sheets can be supplied with metallic
wire mesh reinforcement and have got anti-stick coating in both faces.
