402- Fluorosilicone Sponge (FVMQ)

Temperature Range (depending on grade):

Constant Low:     -62°C          Intermittent Low:           -80°C

Constant High:    204°C         Intermittent High:           220°C



Fluorosilicone closed-cell sponge can be used in most gasketing applications.

The material is flexible and compressible and designed for use in extreme temperature ranges, with excellent weatherability, compression set resistance, electrical strength and non-stick properties.

Available in a range of Widths and Thicknesses.



It is often the material of choice for applications containing oils and fluids that would degrade normal elastomers.
