Material Guide: Fluorosilicone Rubber

Our Guide To FVMQ – Fluorosilicone Rubber

Fluorosilicone Rubber (FVMQ) can operate over a very wide range of temperatures. Their resistance to di-ester lubricants, ozone and weathering, is excellent.

What Are The Advantages Of FVMQ?

Combining the favourable characteristics of fluorocarbons and silicones, FVMQ has a whole host of advantages for use in sealing solutions across a wide range of applications. FVMQ has good electrical strength and moderate oil resistance. It also has excellent weather, ozone, mineral oil, chemical, flame and heat resistance.

What Are The Disadvantages Of FVMQ?

Despite its many advantages, FVMQ is particularly expensive and is unsatisfactory for use with phosphate esters. Like silicone rubbers. Similar to silicone rubber, FVMQs physical properties and impermeability to gases are poor.

What Are The Typical Applications Of FVMQ?

Typical applications of FVMQ include:

• Aerospace fuel system components
• Diaphragms
• Gaskets
• Hose lining
• Seals
• O-rings.

What Temperatures Can FVMQ Operate Under?

The typical working temperature range for FVMQ ranges from -60°C to +200°C.
