TPV and TPE/TPU three cable material difference

Name explanation
TPV is Thermoplastic vuicanizate abbreviation, the Chinese name for thermoplastic EPDM dynamic elastomer or thermoplastic EPDM dynamic vulcanized rubber, is highly vulcanized EPDM particles dispersed in the continuous polypropylene PP phase composed of polymer elastomer materials.
TPE (ThermoplasticElastomer), is a thermoplastic elastomer materials, with high strength, high resilience, injection molding characteristics, a wide range of applications, environmental protection, non-toxic safety, excellent coloring.
TPU (Thermoplastic Urethane) Chinese name for thermoplastic polyurethane elastomers, TPE is one of the categories, TPU is made of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and macromolecular polyols, chain expander polymerization of macromolecules reacted together.

The difference between TPV material and TPE and TPU

1, specific gravity difference.
TPV (0.90-0.97).

2.Difference in oil resistance.
TPV environmental performance similar to EPDM (EPDM), oil and solvent resistance and chloroprene rubber similar performance; high surface grade, feel good; TPE to oil resistance is a certain degree of difficulty, but feel good, soft and smooth; TPU oil resistance and waterproofing; TPE (0.89~1.3); TPU (1.0~1.4); 2, oil resistance difference.
TPU oil resistance and water resistance is better, feel the friction is strong, smoothness is not good.

3.the difference in temperature resistance.
TPV (-60 degrees Celsius ~ 150 degrees Celsius).
TPE (-50 degrees Celsius ~ 90 degrees Celsius).
TPU (-40 degrees Celsius ~ 90 degrees Celsius).

4. the difference between resilience and abrasion resistance.
TPU’s resilience and abrasion resistance is better than TPV and TPE.

5,.the difference in hardness range.
TPV hardness range between 25A~65D, can meet a wide range of hardness requirements.
TPU (35 ~ 90A, 50 ~ 80D), of which the most common hardness is 80 ~ 95A, hardness 50 ~ 80D TPU not much practical application; hardness 35 ~ 75A TPU material cost is higher

TPV materials and TPE and TPU performance.
TPV can be used in the temperature range of -60 ℃ ~ 150 ℃, the application of a wide range of temperatures; hardness Fan used in the 25A ~ 65D between the hardness to meet a wide range of hardness requirements, has a better weather resistance, has excellent anti-aging, royal oxygen and ultraviolet resistance, environmental protection and non-toxic, light specific gravity (0.90-0.97), the appearance of quality and uniformity, the surface of the high grade, feel good, suitable for cold and complex working environments. Complex working environment.
TPE has excellent elasticity and flexibility, cold resistance, able to maintain good elasticity performance at different temperatures, and anti-wear, cut resistance and other characteristics, able to withstand a certain amount of friction and scratching. It has good corrosion resistance to general acids, alkalis, oils and other chemicals, and is suitable for cold and complex working environments.

TPU is characterized by high strength and good abrasion resistance. The main characteristics are: wide range of hardness, and with the increase in hardness, its products still maintain good flexibility and wear resistance, high mechanical strength, outstanding cold resistance, good processing performance, oil resistance, water resistance, mold resistance, acid and alkali corrosion resistance. Suitable for marine acid and alkali oil pollution environment.
