多元醇和二异氰酸酯反应形成的段称为“软段”,使聚氨酯具有更好的柔软性

由多异氰酸酯和扩链剂形成的段称为“硬段”,这使聚氨酯具有更好的刚性和硬度

由软段和硬段组成的聚氨酯树脂只含有聚氨酯,因此可能不适合称之为聚氨酯

从广义上讲,聚氨酯甚至异氰酸酯的加成聚合物

Thermoplastic Polyurethane High Temperature Resistance

Product Details

Thermoplastic PolyurethaneHigh temperature resistance

The so-called polyurethane is the abbreviation of polyurethane, which is formed by the reaction of polyisocyanate and polyol.

The molecular chain contains many repeating carbamate groups (- -NH- -CO- -0-) in actual

In the synthetic polyurethane resin, in addition to the urethane group, there are groups such as urea and biuret. Macromolecule

The segment formed by the reaction of polyol and diisocyanate is called “soft segment”, which gives polyurethane better softness;

The segment formed by polyisocyanate and chain extender is called “hard segment”, which gives polyurethane better rigidity and hardness.

The polyurethane resin composed of soft and hard segments only accounts for urethane, so it may not be appropriate to call it polyurethane.

Broadly speaking, the addition polymer of polyurethane and even isocyanate.
