Fluorosilcone Gum (FCMQ)

Explain :

The main chain of FVMQ is the same as that of SI, which is composed of silicon-oxygen bond (si-o-si), but the groups on the silicon atom are methyl and trifluoropropyl. Therefore, on the basis of maintaining the excellent properties of SI, such as heat resistance, cold resistance, high pressure resistance and weather aging resistance, FVMQ also has excellent hydrogen-resistant solvent, oil resistance, acid-alkali resistance and lower surface properties due to the introduction of fluorine-containing groups. Generally used temperature range: - 50 C - 200 C

Chemical Structure :

Advantage :

Suitable for special use, such as antioxidant chemicals, solvents containing aromatic hydrogen and solvents containing chlorine, in order to prevent products from being corroded.

Disadvantages :

1. The price is relatively high.

2. The mechanical strength is low and the reinforcing process is complex.

Purpose :

1. Aerospace aircraft, automobiles, petrochemical industry, machinery, artificial organs and other important industrial sectors, as well as national defense, transportation, medicine, electronics and electrical fields.

2. Seals, O-rings, diaphragms, connectors, pipes and other products in contact with fuel oil and lubricating oil in high-grade automobile engines.
