Fluorosilicone

Fluorosilicone products type FVMQ ( ASTM D 1418)
Working temperature : -60°C to +230°C 3
These products have a good resistance to solvents, fuels, organic and silicone oils.
These elastomes are used for the manufacture of molded items, extruded seals, cut flash and seals
vulcanized in place. They maintain their mechanical characteristics over a broad temperature range.
