TPE(Thermoplastic Elastomer) is a Thermoplastic Elastomer (Thermoplastic Elastomer) material with high strength, high elasticity, injection molding, wide range of applications, environmental protection, non-toxic and safe, and excellent colorability.
TPU(Thermoplastic Urethane), known in Chinese as Thermoplastic polyurethane elastomer, is a type of TPE. TPU is a kind of polymer material composed of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), macromolecular polyol and chain extender.
Ii. Differences between TPE and TPU:
1. Specific Gravity Difference:
TPE (0.89~1.3);
TPU (1.0~1.4);
2. Difference in oil resistance
TPE to oil resistance is a certain degree of difficulty, but feel good, soft and smooth;
TPU has good oil resistance, strong hand friction and poor smoothness.
3. Differences in temperature resistance:
TPE (-60 ℃ ~105 ℃);
TPU (-60 ℃ ~80 ℃);

4. Differences in resilience and wear resistance:
TPU has better resilience and wear resistance than TPE.
5. Differences in hardness range:
TPE (0~100A);
TPU (35~90A, 50~80D), the most common hardness is 80~95A.TPU with hardness of 50~80D is rarely used in practice.Hardness 35~75A TPU, high material cost.TPU is characterized by high strength and good wear resistance.The main characteristics are: wide hardness range, and with the increase of hardness, its products still maintain good elasticity and wear resistance, high mechanical strength, cold resistance outstanding, good processing performance, oil resistance, water resistance, mold resistance, good recycling.
