Polyester-based vs. Polyether-based This is the most common classification method, with the main difference lying in the soft segment | ||
Characteristic | Polyester-based TPU | Polyether-based TPU |
Mechanical Strength | Excellent (superior tensile and tear strength) | High, but slightly inferior to polyester-based |
Abrasion Resistance | Excellent | Good |
Hydrolysis Resistance | Poor (prone to decomposition with long-term water exposure) | Excellent (suitable for underwater or humid environments) |
Low-Temperature Resistance | General | Excellent (maintains elasticity below -35℃) |
Oil/Chemical Resistance | Excellent | Good |
Antimicrobial Resistance | Weak | Strong |
Main Applications | Shoe soles, tubing, conveyor belts, seals | Cable sheathing, water sports equipment, medical devices |
Aromatic vs. Aliphatic | |||
Type | Structural Characteristics | Key Properties | Application Scenarios |
Aromatic TPU | Contains benzene ring structure | Lower cost, strong mechanical properties, but prone to yellowing (under UV exposure) | Phone cases, shoe materials, industrial parts |
Aliphatic TPU | Does not contain benzene ring structure | Excellent yellowing resistance, high optical transparency, good chemical stability | Paint Protection Film (PPF), aerospace, high-end medical |
