FVMQ – Fluorosilicone Rubber

Fluorosilicones (FVMQ) can operate over a very wide range of temperatures.

  • Their resistance to di-ester lubricants, ozone and weathering is excellent.
  • They have good electrical strength and moderate oil resistance.
  • However, they are particularly expensive rubbers and unsatisfactory for use with phosphate esters.
  • Like Silicone rubbers, their physical properties and permeability to gases are poor.
  • Typical applications include aerospace fuel system components, diaphragms, gaskets, hose lining, seals and O-rings.
  • Typical working temperature range: -60°C to +225°C
