Sealing technology manual for the process industry

Fluoroprene® XP in the chemical industry If the resistance of FKM is insufficient and the use of perfluoroelastomers is assessed as not economical, then the material Fluoroprene® XP can be an interesting alter- native, provided that the process media used are not too aggressive. Due to the variety of possible applications and parameters, a comprehensive technical clarification is sug- gested. We recommend that you consult our application advisory service.
