What is the difference between polyether type and polyester type TPU

The difference between polyether type and polyester type TPU

(1) Advantages of polyether type and polyester type TPU

Polyether type (Ether) : high strength, hydrolysis resistance and high resilience, good low temperature performance.

Polyester (Ester) : good tensile properties, flexural properties, friction resistance, solvent resistance and high temperature resistance.

(2) Performance comparison

Tensile strength, tear strength, wear resistance, drug resistance, transparency: polyester > polyether

Resistance to bacteria, low temperature impact: polyester < polyether
