Function and maintenance of PU duct hose
EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. The main features of EPDM is its superior resistance to oxidation, ozone and corrosion. In addition, due to the molecular structure, it has excellent vulcanization property. Because of the great property, it is widely used in car parts, waterproof material, wire and cable sheath, seal, etc. Then next let me introduce you the properties of EPDM hose in details.
EPDM hose is cost-effective
EPDM has a very low raw rubber density and is the lightest rubber. Moreover, it can absorb a large amount of oil and fillers. While at the same time has almost no negative impact on the properties of EPDM. Thus this greatly reduces its cost.
Corrosion resistant
EPDM rubber lacks polarity and has a low degree of protection. Thus it has strong resistance to various acid and alkali, alcohol, oil, grease, oxidant, etc. However, under the action of melting for a long time, the performance of EPDM rubber hose will decline.
EPDM hose has a wide operating temperature range
EPDM rubber hose can work at 120℃ for a long time. While it work at 150℃shortly.
Excellent insulation property
EPDM rubber has excellent electrical insulation property and corona resistance. And its electrical property is better than or close to SBR and PE.
Excellent aging resistance
EPDM tube can resist weather, ozone, UV, heat, etc. Thus it the best material for the works in a high temp environment. For example, steam hose. Besides, EPDM pipe is ideal for outdoor use.
