Fluorine content (That is, the single structure)Rubber seals have various types and promote industrial development speed. fluorine rubber plug seals are widely used in automotive, electronics, ships and other working environments with high accuracy, high temperature resistance, high wear resistance and harsh conditions.Due to the development of industrial technology, the material of fluorine rubber pan-plug seal is also constantly improving and innovating. Dongsheng seal tells you that the following is the widely used Performance and scope of application of fluorine rubber.
Fluorine rubber pan plug seal (Spring Seal/spring energized seal/Variseal)It is a high-performance seal with a special spring inside the U-shaped iron and fluorine Dragon, which is added to the system fluid pressure by the appropriate spring force to seal the lip (Face)Gently press the sealed metal surface to create a very good sealing effect.
First, the fluorine rubber plug-in seal has better resistance to high temperature than silicone rubber, and some have chemical resistance, resistance to most oil and solvents, weather resistance and ozone resistance;Cold resistance is general, and the temperature range of pan-plug seals is-20 ~ At 250 ℃, the special formula of pan-plug seal can be low temperature resistant-40 °c.
1. Advantages: heat resistance to 250 ℃;It has the ability to resist most oil products and solvents, especially all acids, fatty hydrocarbons, aromatic hydrocarbons and animal and vegetable oils.
2. Disadvantages: it is not recommended to use ketone, low molecular weight Ester and nitrate-containing mixture;Cars, locomotives, diesel engines and fuel systems.
Two, full fluorine rubber pan-plug seal
1. Advantages: heat resistance;Excellent chemical resistance;
2. Disadvantages: poor low temperature resistance;High raw materials;High difficulty in production;
3. Scope of Application: The whole fluorine series products are widely used in the semiconductor industry and information related industries, as well as various high vacuum sealing processes.
