High temperature resistant sealing ring is generally used: carbon fiber filled PTFE, temperature resistance: 265 degrees, can be used for dynamic sealing. If it is used for static sealing, flexible graphite clip metal, temperature resistance: 650 degrees.
SIL silicone rubber sealing ring: has excellent heat resistance, cold resistance, ozone resistance, resistance to atmospheric aging performance. It has good insulation properties. However, the tensile strength is worse than the general rubber and does not have oil resistance. Suitable for household appliances such as electric water heaters, electric irons, microwave ovens, etc. It is also suitable for all kinds of products that are in contact with the human body, such as kettles, drinking fountains, etc. Not recommended for use in most concentrated solvents, oils, concentrated acids and sodium hydroxide. The general use temperature range is -55~250 ℃.
ACM acrylic rubber sealing ring: it has excellent resistance to oil, high temperature resistance and weather resistance, but its mechanical strength, compression deformation rate and water resistance are slightly worse. Generally used in automobile transmission system and power steering system. Not suitable for hot water, brake oil, phosphate ester. The general use temperature range is -25~170 ℃.
