Due to the versatility of the seal, it has been widely used in a variety of temperature and vacuum applications. Not only improves the sealing performance, but also makes its installation and disassembly more convenient. Low temperature greases are silicon-free hydrocarbon products with a wide range of sealing materials including fluororubber, silicon-compatible, nitrile (> 30% nitrile content), nylon, polyurethane, polyethylene and polypropylene.
Excellent sealing performance, waterproof without leakage; Good fresh-keeping effect, completely non-toxic and tasteless; Can be heated under high temperature, no deformation, no harmful substances; Good tensile resistance, through special inspection and testing; Long-term use unchanged yellow does not fade; Corona resistance, arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance, in line with standards.
Heat resistance: silicone rubber has much better heat resistance than ordinary rubber, can be used almost forever at 150° without performance changes, can be used continuously at 200° for 10,000 hours, and can be used for a period of time at 350°. Widely used in situations requiring heat resistance, hot water bottle sealing ring, pressure cooker ring heat resistant handle.
Cold resistance: Ordinary rubber delay is -20 ° -30 °, that is, silicone rubber still has good elasticity when it is -60 ° -70 °, and some special formulations of silicone rubber can also withstand extremely low temperatures, such as: low-temperature sealing rings.
