PU is mainly divided into two categories: polyether polyurethane and polyeter polyurthane. By adjusting the recipes, different physical properties, such as cold resistance, density and flexibility, can be obtained, degraded in nature, resistant to a variety of acid and alkali and organic solvents, and is widely used to replace rubber products in the harsh environment.

EPDM is an ethylene-propylene rubber, which has good heat resistance, aging resistance, low temperature resistance, low water absorption and good insulating property. Its widely used in automotive parts, fire hose, waterproof construction materials. It has better resistance to chemicals. However, it has poor stability in fat genera and aromatic solvents and mineral oil.

NBR has good tolerance to mineral oil, vegetable oil, benzene, gasoline, common dilute acid and especially oil. However, better oil_resistance is often associated with poor cold resistance. It has good heat resistance, wear resistance. Its disadvantages include poor cold resistance, low strength.

The hose can be delivered only passing the inspection of the quality inspection department of the manufactory.The products of same variety, same specification, same material and made on same day are regarded as one batch, from which two sticks shall be taken randomly as the specimen.
