Polyurethane belongs to a type of polymer elastomer.

Polyurethane, abbreviated as PU, is a polymer formed by connecting amino acid esters. Most polyurethane is a thermosetting polymer that is not easily melted when heated. Polyurethane contains two monomers, namely trimeric isocyanate and polyol, which are alternately combined, so polyurethane is also known as an alternating copolymer.

Polyurethane has many uses: it can be used to make durable elastic wheels, such as skateboard wheels, roller coaster wheels, etc; It can also be used to make rigid foam heat insulation panels, high elastic foam seats, etc. It can be processed with different additives, making polyurethane more widely used.

Chemical properties: Polyurethane is resistant to corrosion from various acids, bases, and organic solvents, and is often used as a substitute for rubber products in harsh environments.

Physical properties: The mechanical properties of polyurethane have great adjustability. By controlling the ratio between crystalline hard segments and non crystalline soft segments, polyurethane can achieve different mechanical properties. Therefore, its products have excellent properties such as wear resistance, temperature resistance, sealing, sound insulation, good processing performance, and biodegradability.
