In the "survival challenges" of industrial equipment, drastic temperature changes and oil erosion are common "killers". Low-pressure modified fluorosilicone rubber is like a "temperature warrior" that can calmly cope with extreme cold from -60°C to high temperature of 200°C, and can resist erosion from various oils and chemicals, becoming a reliable guardian of equipment in extreme environments.

The "temperature difference resistance talent" of this material is particularly eye-catching. Whether it is outdoor pipelines in cold winters in the north or engine compartments operating at high temperatures, it can maintain stable performance - it will not harden and become brittle at -60°C, nor soften and flow at 200°C, always maintaining good elasticity and sealing. This characteristic makes it perform prominently in scenarios with frequent alternations of cold and heat, such as fuel systems of aircraft and engine oil seals of automobiles. Even after repeated temperature difference impacts, it can firmly hold the sealing line of defense.

Oil and solvent resistance is another "hardcore skill" of it. After being immersed in Fuel C for 72 hours, the volume change rate is ≤20%, which means that there will be no obvious expansion or cracking after contact with common oils such as gasoline, diesel, and lubricating oil. This is crucial for automobile oil seals and pump valve seals in petrochemical industry, which can effectively avoid oil and liquid leakage caused by material aging and reduce equipment maintenance costs.

The balance between strength and elasticity is even more a plus. Its tensile strength is ≥9MPa, which is equivalent to being able to withstand a force of 90 kilograms without being pulled off. At the same time, the elongation at break can reach up to 380%, which can be greatly stretched and then restored to its original shape. This "strong but not brittle, elastic but not soft" characteristic allows the seals made of it to resist the impact of equipment vibration and closely fit the contact surface to avoid gap leakage.

Usage tips: Different hardness models (40A-70A) are suitable for different scenarios. Choose 40A if high flexibility is required, and 70A if high wear resistance is required; it is recommended to use 0.6-1 part of di-2,5 vulcanizing agent during processing. Excessive proportion will affect the aging resistance; after vulcanization, it needs to be fully cooled before use to avoid testing performance at high temperature.
