FLUOROSILICONE RUBBER SHEET GASKETS

This Fluorosilicone (FVMQ) Rubber Sheet Gasket is a specialized engineered material formulated to provide controlled static dissipation alongside the exceptional environmental resistance inherent to fluorosilicone elastomers. By incorporating carefully selected conductive fillers, it offers a reliable, permanent path for the controlled bleed-off of electrostatic charges, thereby preventing spark risks and electrostatic discharge (ESD) damage, all while maintaining superior resistance to fuels, o

FLUOROSILICONE (FVMQ) RUBBER SHEET GASKET

A Fluorosilicone (FVMQ) Rubber Sheet Gasket is a high-performance sealing component engineered for the most demanding environments where exposure to fuels, oils, solvents, and extreme temperatures is prevalent. As a specialized variant of silicone, fluorosilicone incorporates fluorine into its polymer structure, granting it exceptional resistance to a wide range of hydrocarbons and chemicals that cause standard silicone rubber to swell and degrade. This makes it the material of choice for critical sealing applications in aerospace, automotive, and chemical processing industries.

Key Features & Benefits

1. Superior Fluid & Chemical Resistance: Offers outstanding resistance to aircraft and automotive fuels (e.g., JP-8, gasoline, diesel), oils, hydraulic fluids, solvents, acids, and bases. It exhibits minimal swelling and property degradation compared to standard silicone.

2. Excellent Temperature Stability: Maintains elasticity and sealing performance across a wide operating temperature range, typically from -55°C to +200°C, with intermittent capability up to 200°C.

3. Long-Term Durability: Provides excellent resistance to compression set, ozone, UV exposure, and weathering, ensuring a reliable, long-lasting seal even after prolonged exposure to harsh conditions.

4. Flexibility & Conformability: Retains good flexibility at low temperatures, allowing it to conform to flange surfaces and fill minor imperfections for an effective seal.

5. Inherent Safety: As a solid elastomer gasket, it provides a permanent sealing solution without the risk of leaching or migration, unlike some liquid gaskets or additives.

Primary Applications

· Aerospace: Critical seals in fuel systems, engine compartments, hydraulic lines, and avionics enclosures.

· Automotive: Gaskets for fuel injection systems, oil pans, transmission seals, and components in high-underhood environments.

· Chemical Processing: Seals for pumps, valves, and reactors handling aggressive solvents, acids, and bases.

· Oil & Gas: Sealing elements in downhole tools, fuel handling equipment, and instrumentation exposed to hydrocarbons.

Key Distinction from Standard Silicone (VMQ)

The primary advantage of fluorosilicone over standard silicone is its exceptional resistance to non-polar fluids (fuels, oils, solvents). Standard silicone will severely swell and lose mechanical properties in such environments, whereas fluorosilicone remains stable, making it essential for applications involving these media.

Typical Specifications & Options

· Material: Fluorosilicone Rubber (FVMQ).

· Temperature Range: -55°C to +200°C

· Hardness (Shore A): 50 to 70

· Standard Color: Black Blue Red Gray and other custom colors.

· Thickness: Available in sheets from 1mm to 10mm and beyond.

· Form: Sheets, rolls, and custom die-cut or stamped gaskets.

Summary

The Fluorosilicone (FVMQ) Rubber Sheet Gasket is the engineered sealing solution for applications where resistance to fuels, oils, solvents, and high temperatures is paramount. It provides reliable, long-term performance where standard elastomers would fail, ensuring system integrity and safety in the most challenging aerospace, automotive, and industrial environments.
