Applications – sealing pumps, valves, tanks and fluid metering devices – require high performance sealing materials with outstanding chemical resistance to various aggressive media and resistance to high and low temperature extremes.
Applications subsea equipment, pipeline connectors, valves, compressors and pumps. Lavelast® offers an excellent chemical resistance, low temperature performance and high pressure environments resistance.
Lavelast® perfluoroelastomer material has been developed to perform under extreme conditions, in temperatures as low as -46°C (-51°F) and Explosive Decompression resistant
For thermal, plasma and wet chemical application.
FFKM grades offer the lowest particle and trace metal contamination for minimized yield loss and low chemical erosion rates.
Lavelast® perfluoroelastomer, its extremely high purity with very low metal ion content and low extractable fractions.
