TPU is a thermoplastic elastomer, abbreviated as “polyurethane” in English. It is a chemical product synthesized from petroleum and natural gas through extraction and chemical reactions. As a raw material, it is widely used in various industries, especially in the production of daily necessities. Watch straps are one of the applications of TPU. Watch straps made of TPU have the advantages of moderate cost and high cost-effectiveness. They have the advantages of non vacuuming, softness, sweat resistance, non toxicity, and high strength. However, there are also defects such as low temperature resistance, insufficient smoothness and delicacy, and easy aging and hydrolysis. Watch straps made of TPU will become hard at minus zero temperatures, and usually age and hydrolyze after about two years of use, losing strength and being scrapped. Watch straps made of TPU feel slightly astringent when in contact with human skin. The sentence is:.
TPSIV is also an English abbreviation for thermoplastic elastomer (currently there is no Chinese translation). It is a product invented by Dow Corning in the United States, which is optimized and upgraded on the basis of TPU. TPSIV aggregates silicon elements in the molecular clusters/chains of TPU, thus changing the physical and chemical performance indicators of TPU and becoming a new material. Its advantages of softness and elasticity remain unchanged under temperature conditions of minus 40 degrees Celsius, and its resistance to aging and hydrolysis is greatly improved to more than 5 years. The service life of the product exceeds 5 years. What is more unique is that the surface of TPSIV is particularly smooth and delicate, and it feels comfortable when in contact with human skin. In summary, TPSIV has all the advantages of TPU. Advantages: Non vacuuming, soft, sweat resistant, non-toxic, high strength, and has advantages that TPU does not have: low temperature resistance, aging resistance, hydrolysis resistance, and smooth and delicate touch.
