Fluorosilicone Rubber Compound

What is Fluorosilicone Rubber Compound

We have many grades of fluorosilicone rubber compound which can be used for producing your sealing products. Fluorosilicone rubber combines most of the attributes of silicone with resistance to petroleum oils and hydrocarbon fuels typical in Fluoroelastomers. As a result, they are often used in aircraft fuel systems.

Fluorosilicone rubber compounds offer superior heat resistance. In addition, they are resistant to cold, oils and solvents of fluorinated rubber. Fluorosilicone rubber compounds are good for special applications where general resistance to oxidizing chemicals, aromatic and chlorinated solvent bases are required. Ease of mastication and excellent release properties make Fluorosilicone suitable for milling, calendaring and extruding. Fluorosilicone improves product performance, reliability and enhanced properties for ultimate yield realization.

Application of Fluorosilicone Rubber Compound

The potential uses of FVMQ Fluorosilicone rubber compound in sealing technology and other sectors are limited only by its high gas permeability, low tensile strength and poor abrasion and tear properties. Typical applications of Fluorosilicone rubber include static seals in fuel systems for cars and in aerospace engineering as well as diaphragm valves for crankcase ventilation. Fluorosilicone rubber is also used in hoses, turbocharger hoses, gaskets, tubes, and in O-rings.

Features of fluorosilicone Rubber Compound

Fluorosilicone rubber compound is resistance to any petroleum products, as well as a wide range of aggressive chemicals, including acids, alkalis and solvents. Its operating temperature range is from -60°C to + 200°C. It has high resistance to ozone aging and gas. It is resistant to sunlight and UV radiation. And it has low level of compression set. Even at extreme temperatures, products do not become excessively soft or fragile. It also has very good dielectric properties, good water resistance and good rebound resilience.

The Types of Fluorosilicone Rubber Compounds We Have.

1. High Rebound Resilience and Low Compression Set Fluorosilicone Rubber Compound

It is transparent or milky white color Fluorosilicone rubber compound, it has good physical performance, low compression set and processing performance. With the characteristics of good elasticity, low pressure change, fast vulcanization speed, and good liquidity, it is more suitable for making sealing products.

2. Extrusion Type Fluorosilicone Rubber Compound

It is transparent or milky Fluorosilicone rubber compound and has good physical performance and processing performance, with characteristics of good recovery, fast vulcanization speed and good liquidity, more suitable for making extruded sealing strips, fluorosilicone tubes and other shape products.

3. High Tear Strength Fluorosilicone Rubber Compound

It is transparent or milky white color Fluorosilicone rubber compound and it has good physical performance and processing performance, have characteristics of good tear resistance, fast vulcanization speed, and good liquidity, and are more suitable for making sealing products with complex structures.

4. Fluorosilicone Rubber Compound for Turbocharger Tubes

It is a translucent turbocharged tube special fluorosilicone rubber compound, which integrates the advantages of silicon rubber and fluorine rubber. This product is developed for car turbochargers and is widely used to produce car turbocharger tubes to meet its harsh requirements and fuel resistance at extreme temperature.
