Adhesive Fluorosilicone Rubber

 

Adhesive fluorosilicone rubber (FVMQ) is a transparent or light yellow elastomer. Products made of fluorosilicone rubber after processing and vulcanizing have good mechanical properties, good high and low temperature resistance (-60~230°C) and oil resistance (various fuels, synthetic oils, lubricating oils). Indispensable materials for rockets, aerospace and other science and technology and other industries.

 

 

Aluda adhesive fluorosilicone rubber is a translucent or milky white adhesive fluorosilicone compound with good physical properties and processing properties, and has the characteristics of good resilience, fast vulcanization speed and good fluidity. Good connection performance, more suitable for making automotive rubber hose products.

Note:

1. Vulcanizing agent: DBPH. Dosage 0.53gDBPH/100 premixed glue

2. One stage vulcanization: 170℃*10Min. Two stage vulcanization: 200℃*4H

 

 

1. Mixing: Remix several times on the open mill, add vulcanizing agent, and then adjust back to 0.5mm-1mm thin pass 8-10 times after the material is finished, and then leave the tablet and park it.

2. Vulcanization: re-mill the fluorine-silicon compound rubber with vulcanizing agent, and then cut it into the required shape, and then use it.

 

 

Fluorosilicone rubber is the most widely used new material of fluorosilicone series. The introduction of fluorine into siloxane not only has the superior heat resistance, weather resistance, hydrophobicity, and mold release properties of general siloxane, but also has the waterproof, oil and solvent resistance of fluorine-containing compounds. Therefore, on the basis of maintaining a series of excellent properties such as high and low temperature resistance, weather resistance, compression recovery, resilience, electrical properties, and film release of silicone rubber, fluorosilicone rubber also has the fuel oil resistance of fluororubber. , Solvent resistance and other properties. Products with low hardness can be obtained even without the use of plasticizers.

 

Now, fluorosilicone rubber has been used in aerospace, aircraft, automobile, petrochemical, machinery, artificial organs and other important industrial sectors, as well as national defense, transportation, medicine, electronics and electrical fields. Especially as seals, O-rings, gaskets, diaphragms, connectors, pipes and other products in contact with fuel oil and lubricating oil in high-end automobiles or machines, they are widely used, except for the military industry. In the civilian market, automotive diaphragms are the most popular market for fluorosilicone rubber.

 

Turbocharger hoses are often lined with rubber-adhesive fluorosilicone rubber. Since the inner liner of the silicone rubber tube of the turbocharger system directly contacts the high-temperature harmful gas discharged by the engine, the rubber of the inner liner is required to be resistant to high temperature, lubricating oil, and fuel oil, and to have good adhesion and processing performance with silicone rubber . On the basis of maintaining the excellent properties of silicone rubber, such as heat resistance, cold resistance, insulation and weather aging resistance, fluorosilicone rubber introduces fluorine-containing groups to make it have good oil resistance and acid and alkali resistance. . Adhesive fluorosilicone rubber has good adhesion to silicone rubber, and is generally used for the inner lining of silicone rubber pipes to block oil and gas in the system to avoid erosion of silicone rubber.
