Polyurethane valve insert seal is used for sealing in the oil industry.
1. PU rubber seal is used for sealing the valve seat of the fracturing pump. It is a vulnerable part of petroleum equipment such as fracturing trucks, cement trucks, plunger pumps, mud pumps, etc., and is also a rubber part matching the valve body of mud pumps for drilling.
2. Polyurethane valve rubber seals is made of polyurethane material. Polyurethane is a kind of polymer material, which is widely used in many fields of national economy because of its excellent performance.
3. Polyurethane is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound. Polyurethane materials are very versatile and can replace rubber, plastic, nylon, etc., and are used in airports, hotels, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, colored stone art, parks, etc.
4. The mechanical properties of polyurethane are highly adjustable. By controlling the ratio between crystalline hard segments and non-crystalline soft segments, polyurethanes can obtain different mechanical properties. Therefore, its products have excellent properties such as wear resistance, temperature resistance, sealing, sound insulation, good processing performance, and degradability. Polyurethane is resistant to various acids, alkalis and organic solvents, so it is often used as a substitute for rubber products in harsh environments.
