Polyurethane elastomer development prospects!

Polyurethane thermoplastic elastomer, also known as thermoplastic polyurethane rubber, abbreviated as TPU, is an (AB) block linear polymer, A is a high molecular weight (1000-6000) polyester or polyether, B is 2-containing In the case of diols of 12 straight-chain carbon atoms, the chemical structure between the AB segments is connected by a diisocyanate, usually diphenylmethane diisocyanate (MDI). Thermoplastic polyurethane rubbers are cross-linked by intermolecular hydrogen bonds or lightly crosslinked between macromolecular chains. As the temperature increases or decreases, the two crosslinked structures are reversible. In the molten state or the solution state, the intermolecular force weakens, and after the cooling or the solvent volatilizes, they are connected together by a strong intermolecular force, restoring the performance of the original solid. Polyurethane elastomer is a kind of polyurethane synthetic material. Because its structure has two segments, soft and hard, it can be designed for molecular, and give the material high strength, good toughness, wear resistance, oil resistance and other excellent performance. Because of its excellent performance, it is widely used in many fields such as automobile, construction, mining, aerospace, electronics, medical equipment, sports products, etc., and has become a promising synthetic material product.

The annual global thermoplastic elastomer (TPE) consumption is 2.26 million tons. In order to better grasp this huge business opportunity and meet the market demand, the international rubber and plastic materials manufacturers have actively developed a variety of new thermoplastic elastomer products. Thermoplastic elastomers have a wide range of applications, and the demand for automotive and medical markets has grown most significantly.
