Understanding Rubber Round Stock
Rubber round stock, also known as rubber rod or cylindrical rubber, is a versatile material available in various shapes and sizes. It’s essentially a solid or hollow cylinder of rubber, manufactured through extrusion or molding processes. Its properties are determined by the base rubber compound and any additives incorporated during manufacturing. The most common rubber types used include natural rubber, silicone rubber, neoprene (CR), nitrile rubber (NBR), ethylene propylene diene monomer (EPDM), and fluorocarbon rubber (FKM or Viton). These materials offer different levels of flexibility, durability, and resistance to various chemicals and temperatures. Companies like www.yodarubber.com specialize in a wide range of rubber compounds.
Technical Features of Rubber Round Stock
The technical features of rubber round stock significantly impact its suitability for different applications. Key properties include hardness (Shore A Durometer), tensile strength, elongation, tear strength, and compression set. These properties are crucial for ensuring the material meets the specific demands of the intended application. Manufacturers like www.sbrrubbersheet.com emphasize strict testing to ensure high-quality products.
