From the commonly used rubber sealing ring material we can divide it into fluorine rubber, silicone rubber, nitrile rubber, neoprene rubber and epDM five.
Rubber sealing ring material
The first type, Viton rubber ring. It is resistant to high temperature, oil, acid and alkali and strong oxidants. Temperatures range from minus 30 degrees Celsius to 260 degrees Celsius. It is mainly used in high temperature, high pressure and vacuum environment, as well as oil environment. They range from aerospace to petrochemical.
The second type, silicone rubber ring, it can also withstand high temperature and low temperature, can be used normally in the environment of minus 70 degrees Celsius to 260 degrees Celsius and good elasticity. Best used for sealing gaskets in thermal machinery.
The third category, nitrile rubber. It is an excellent aromatic solvent and oil resistant, so it can be used to make oil resistant sealing products, but it is not resistant to ketones, hydrogen chloride and esters.
The fourth type, neoprene rubber ring, is well resistant to solvents and chemical media and to oil. Ozone resistance, oxidation resistance and weathering resistance. In life, it can be made into doors and Windows sealing strip and diaphragm and vacuum sealing products can be seen everywhere.
The fifth category, EPDM rubber ring, in the door and window sealing strip and the automotive industry is used more, with excellent performance of temperature resistance, oxidation resistance, ozone resistance and weathering aging.
