Polyurethane (PUR) is a large class of polymers containing more urethane group features in the main chain of the molecule. It is a polymer material between plastic and rubber. It has a high elongation. Wide range of hardness, large formula adjustment range, excellent wear resistance and mechanical properties. Castable polyurethane elastomer (CPUR) is the most important one of the three major processing types of polyurethane elastomer. Its dosage accounts for 6o% of PUR. It has diversified chemical structure, easy viscosity adjustment, excellent processing technology and easy It is suitable for the production of large and complex components due to its advantages of industrial production, ease of use and fast curing. Polyurethane wear-resistant lining is produced by casting polyurethane elastomer. Polyurethane is a kind of polymer containing a urethane-type repeating structural unit in a macromolecular chain, and is called a polyamino acid ester. The English name is polyurethane, which is referred to as PU or PUR. PU is a product which is reflected by a polyisocyanate and a polyether or polyester polyol at a certain ratio.


Properties of PU Elastomers: The properties of PU elastomers differ slightly from the properties of PU elastomers synthesized from plastic polyols. Polyester PU has high mechanical properties and good oil resistance, but its water resistance is poor. Polyether PU has better low temperature resistance and hydrolysis resistance than polyester, but its oil resistance and mechanical properties are slightly worse.


Mechanical properties of PU: The hardness of PU elastomer varies widely, from Shore A10 to D80, and elongation at break is as high as 600%~~800%. The highest Shore hardness of natural rubber is only A70, and the elongation at break is 550%. The PU elastomer has a higher tear strength and is 2 to 5 times larger than natural rubber. The PU elastomer has high resilience and good shock absorption. The PU elastomer has good wear resistance and is 3 to 10 times that of natural rubber.

With the continuous development and improvement of polyurethane, the application of polyurethane has penetrated into our life. Such as: automobile production, mine beneficiation, port terminal, food and food processing, medical and health, construction machinery, electronic equipment, construction, furniture, textile and apparel footwear, synthetic leather, water conservancy, petrochemical, printing and packaging, sports and fitness industries. There are a large number of applications, and with the advancement of technology, polyurethane is gradually being applied in our aerospace and defense industries.
