PU/AU/EU

1、physical and chemical properties

Polyurethane is the abbreviation of Polyurethane Dicarboxylate, PU is the abbreviation of English Ploy Urethane. From the physical properties, low hardness materials to AU as the superior, in addition, AU oil resistance, heat resistance and adhesion with the metal are better, and resistance to hydrolysis, cold resistance and antibacterial properties such as the EU is good. Because the hydrolysis resistance of the ether bond is much stronger than that of the carboxylate bond (about 5-10 times), the EU is less hydrolysable and is more resistant to oil and fuel than nitrile rubber (NBR) and hydrogenated nitrile rubber The The presence of lactone type polyurethane elastomer improves the hydrolysis resistance of AU, and the oil resistance and high temperature resistance have also been improved step by step.

2、 the temperature range

AU: -40 to 100 ° C

EU: -80 to 90 ° C

PU: -40 to 90 ° C

3、hardness range

Shore A60 degrees to 95 degrees

4、color

Transparent, green, yellow, orange, black, can also be specified by the customer color.

5、 application

Polyurethane elastomer can be in a wide range of hardness with high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and anti-vibration, with "wear-resistant rubber," said. Polyurethane elastomers are produced in polyurethane products, but polyurethane elastomers have excellent overall performance and are widely used in industrial sectors such as metallurgy, petroleum, automobile, mineral processing, water conservancy, textile, printing, medical, sports, food processing and construction The

1) Automotive industry - seals, tires, bumper, shock absorbers, pipes, belts, shock absorbers, etc.

2) in the machinery industry applications - seals, rubber roller, tape, etc .;

3) mining industry - sieve plate, shaker and so on

4) light industry - polyurethane shoe material, polyurethane synthetic leather, polyurethane fiber.
