FKM Rubber Compound

FKM rubber compound is a base compound made of polyorganosiloxane containing vinyl linear polymers with reinforcing fillers, incremental fillers and additives that give various properties, raw rubber or plastic rubber according to the formula and the compounding agent by the rubber mixing machine is called compounding rubber.

Fluorine rubber has the characteristics of heat resistance, oil resistance, solvent resistance, strong oxidant resistance, etc. due to the presence of fluorine atoms on the carbon atoms of the main chain and the side chain, and has good physical and mechanical properties. It has the best comprehensive performance among all synthetic rubbers. Commonly known as the rubber king. Fluorine rubber is widely used in aviation, aerospace, automobile, ship, petroleum and other fields, and one of its main uses is as an oil seal for automobile engine crankshafts. Among them, the crankshaft of the engine has a high speed, and the sealing products have to bear high friction torque. In the case of poor lubrication effect, the heat generation in the sealing area will be large, which will cause the rubber to become sticky or improve the adhesion performance with metal, and resist wear. Degraded performance can damage the seal, which in turn can lead to seal failure.

Material compounding is an important means to solve the problem of reducing friction and improving wear resistance of materials, and lubrication is an important way to reduce friction and wear. The use of single lubricant will bring pollution to the working environment, especially for some food processing machinery and precision machinery. Lubrication of electronic equipment machines. Since polymers have relatively low surface tension and are suitable for working under dry friction conditions, the application of polymers and their composites in friction and wear has received widespread attention. Molybdenum disulfide and graphite are solid lubricating materials with excellent performance. They have excellent lubricity under harsh conditions such as high temperature, low temperature, high load, high speed and chemical corrosion, which makes the vulcanizate lubricious, and when the lubricant is vulcanized from vulcanized, it has excellent lubricity. When the glue is sprayed out, a lubricating film can be formed on the surface of the rubber product to produce a self-lubricating effect.

By adjusting the formula and adding a certain proportion of anti-friction materials, our company improves the friction and wear performance and thermal stability of the fluorine rubber, making it the best friction and wear performance, and the thermal decomposition temperature of the fluorine rubber is higher than that of the fluorine rubber without lubricant. increased by about 7°C.

Rubber Compound Performance

FKM Rubber Compound Features

FKM rubber compounds are particularly resistant to high temperature, ozone, weather, oxidation, mineral oil, fuel oil, hydraulic oil, aromatic and many organic solvents and chemicals. FKM system blends are now available, such as general type (66% fluorine content), medium fluorine content type (67~68.5% fluorine content), high fluorine content type (70% fluorine content), improved low temperature elasticity type (64.5~67% fluorine content) and more chemical and solvent resistance properties (66% fluorine content).

For general types, the standard operating temperature is limited to approximately -26℃(-15℉) to 232℃(450℉) at static temperature. When used in dynamic applications, the temperature is between -15℃ and 200℃.

Because of its high temperature, oil, solvent, flame, chemical and weather resistance properties, FKM is commonly used in the automotive, chemical processing, aerospace and many other industries.

FKM rubber compounds have excellent heat resistance; excellent resistance to oils, gasoline, hydraulic fluids and hydrocarbon solvents.

FKM Rubber Compound Applications

Silicone compound is an environmentally friendly material with excellent characteristics such as non-toxic and tasteless, high and low temperature resistance, insulation, and chemical stability, so FKM compound is used in various industries. For example, auto parts, sanitary ware, arts and crafts, machinery parts, medical equipment, aviation equipment and other industries have important applications of FKM compounding rubber.
