NBR/ EPDM rubber expansion joint offers a number of advantages, and is usually used in piping to prevent damage to surrounding structures. These NBR/ EPDM rubber expansion joints help to provide relief from thermal, extension and contraction stresses in pipes or duct installations.NBR/ EPDM Rubber are widely used in the industries such as petroleum, chemical industry, paper making, construction, water supply and sewerage works.
EPDM rubber for ethylene propylene diene monomer rubber. EPDM has excellent acid, oil performance. The refers to how it's classified according to the ASTM standard D-1418. The rubbers that fall under the M class all have a saturated chain of polyethylene. The ethylene content of EPDM is usually between 45% and 75%, and the higher the ethylene concentration, the higher the loading potential.
NBR rubber is also a good choice，It is Suitable for particulate media.NBR rubber having excellent oil resistance, oil resistance after its polysulfide rubber and fluorine rubber, and has wear resistance and airtightness.
