Structural Characteristics, Distinct Advantages

The main chain of fluorosilicone rubber raw rubber is siloxane bonds, and the side chains carry trifluoroalkyl groups. This special structure gives it unique properties. Manufactured through the ring - opening polymerization of cyclic siloxanes, similar to the polymerization method of dimethyl silicone rubber, it can work stably in a wide temperature range from - 60℃ to 200℃ despite being slightly inferior to other fluororubbers in terms of heat and chemical resistance. It also has good fuel oil resistance and little swelling in methanol, combining the strengths of silicone rubber and fluororubber.

Wide Applications, Industry Favorites

In the aviation field, for fuel - oil and lubricant - resistant seals and contacts on aircraft, the IOTA 3110 - F series is a reliable choice. In the automotive sector, it is commonly used in vehicle components such as sealing rings and oil seals. In the petrochemical industry, it is suitable for manufacturing seals for equipment like pumps and valves that need to resist high and low temperatures and chemical corrosion. In the medical field, it provides appropriate materials for medical devices and artificial organs. In the military industry, it can meet the requirements of low - temperature, oil, and acid resistance in harsh environments.

Indicator Control, Stable Performance

The series offers raw rubber with different vinyl contents. The molecular weight is consistently between 800,000 and 1,000,000, and the volatile content is controlled at ≤3%, with vinyl end - capping. Vinyl content has a significant impact on the performance of vulcanized rubber. An increase in vinyl content raises the cross - linking ratio, leading to higher hardness and tensile strength of the vulcanized rubber, while reducing elongation and compression set. Vinyl - end - capped raw rubber generally outperforms non - vinyl - end - capped raw rubber. Our company uses high - purity D3F as a raw material, ensuring a more uniform distribution of vinyl groups on the side chains. This improves the cross - linking density and rebound resilience, guaranteeing stable product performance.
