Comprehensive Guide to O-Ring Rubber Bands in China
O-rings have got their name because of their circular cross-section. They act as essential sealants by providing a protective layer between components, preventing leakage and ensuring that liquids or gases do not escape. Due to their versatility, O-rings can be used for both static and dynamic applications. Various manufacturing techniques like injection, extrusion, and compression molding are employed to produce O-rings, with the choice of raw materials depending on the specific application. The most commonly used materials include nitrile rubber, silicone, EPDM rubber, and fluorocarbon (Viton).
