Optimize Total System Cost - Brochure
According to this brochure, chemical, petrochemical and pharmaceutical processes can save from 10% to 200% in total system operating costs (depending on equipment, chemical environment and previous seal material) by switching to Kalrez perfluoroelastomer seals. The brochure cites case history examples from a global agrochemical producer and a process pump manufacturer.

Viton GF and Viton ETP fluoroelastomers
Dubbed Viton GF and Viton ETP, these new fluoroelastomers have been developed with advanced polymer architecture (APA) technology that provides much better chemical resistance than Viton A, which has been the backbone of the Viton line until now. Laboratory tests have shown that APA provides improved resistance to steam and some cleaning fluids used in food and pharmaceutical processes compared to older diamine- or bisphenol-cured dipolymer fluoroelastomers. The new materials are being used in gaskets, O-rings and custom-molded parts for critical sealing applications.
