FVMQ Fluorosilicone O-rings
FVMQ Fluorosilicone is a widely used elastomer that can be compounded to meet a wide range of applications.
Description
FVMQ Fluorosilicone o-rings combine silicone and FKM to provide excellent jet fuel resistance and performance at both high and low temperatures. They feature excellent flexibility, compression resistance, ageing and sunlight resistance, and an overall wide range of basic chemical resistance.
Fluorosilicone, like silicone, does not have strong mechanical characteristics. These weak physical qualities limit its applicability in dynamic applications.
Advantages and Benefits
FVMQ fluorosilicone o-rings are well suited for both high- and low-temperature environments with a working temperature range of -60°C to 200°C. Other important characteristics include:
- Resistance to fuel, oil and solvents
- Good compression set and resilience properties
- Excellent resistance to air, sunlight and ozone
- Suitable for exposure to chlorinated and aromatic hydrocarbons
- Recommended for use with petroleum oil, jet fuel and mineral oils
While oil and fuel resistance makes fluorosilicone an excellent choice for the aerospace industry, this polymer is becoming an increasingly popular material for a wider range of sealing applications.
Applications
Various applications in the aerospace and automotive industries use FVMQ fluorosilicone O-rings. These applications include:
- Automotive fuel emission control systems
- Fuel pumps and tank seals
- Low-outgassing applications
- Electrical housing seals
- Aerospace fuel systems
- Engine gaskets
