Introduction
1.O-ring seal series has a variety of materials such as fluorine rubber, butadiene rubber, silicone, etc., which are widely used in various machinery, resistant to various petroleum base oils and various chemical media: the use of non-rubber types can meet -60 In the temperature range of ℃-+ 300 ℃, the use pressure range: <10MPa (hydraulic), <1MPa (pneumatic) <16MPa (static seal) butadiene rubber and gasoline resistant (90, 93, 97) expansion rate is 0.
2.Y-type seals are made of fluorine rubber, butadiene rubber, chloro rubber, and other materials. They are widely used in hydraulic, mechanical, pneumatic and other industries. Seed-resistant petroleum-based oils have excellent abrasion resistance, and different types of rubber can be used to meet the temperature range of -60 C to + 300 C.
3. Silicone rubber series is equipped with advanced testing equipment and clean dust-free workshop. Products are widely used in electronics, medical equipment, food and other industries.
The rubber type uses a variety of domestic and imported silica gels, and the operating temperature can meet -60 -+ 300 C. The products can meet oil resistance, steam resistance, medical, edible full transparency, high strength, flame retardant, conductive silicone rubber, etc.
4. Fluoro rubber series products The company's fluoro rubber series products are widely used in automotive, shipbuilding, military, electronics and other industries. The working temperature is -40 C + 300 C. It is resistant to fuel oil, high temperature, Freon, and Hot water, steam and excellent chemical resistance are welcome.
5. PTFE series products PTFE gasket has high temperature resistance and corrosion resistance, even if it does not work with concentrated acid, alkali or strong oxidant at high temperature, it has been widely used as a sealing material. Suitable for sealing devices on pipes, flanges, reactors, valves and containers. Shaped parts are produced according to user design drawings.
6. Various special-shaped miscellaneous materials are selected from Ding Qing, natural, fluorine rubber, silicone, etc., widely used in automotive, machinery, valves and other industries. Different rubber types can be selected to meet the temperature range of -50 ℃-+ 250 ℃ The product has good abrasion resistance and flexural performance, and can be designed according to requirements.
