a brief discussion on tpu film and other plastic materials

thermoplasticTPUelastomer tpu (thermoplastic polyurethane) is made from mdi and polyol with nco functional groups, 1.4bg containing oh functional groups by extrusion and mixing, becausetpu filmit has good elasticity, good physical properties and various mechanical strengths. all is well. therefore, it is widely used in processing methods such as injection, extrusion, calendering and dissolution into solution resin. it is a plastic material often used in the plastic processing industry. its products cover industrial applications and household necessities.

in recent years, due to the continuous development of new products, the number of thermoplastic pu elastomers has continued to increase, creating new opportunities for the plastics processing industry to provide low-cost and high-added value industries.

tpu film(thermoplastic polyurethane) is becoming more and more popular due to its excellent functionality and environmental protection concept. now, tpu can replace pvc wherever pvc is used. however, the advantages of tpu are beyond the reach of pvc. tpu not only has excellent high tension, high tension, toughness and aging resistance properties, but it is also a mature environmentally friendly material. now,tpu film manufacturersour products have been widely used in: shoe materials, ready-made clothing, inflatable toys, water sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, leather bags, etc. based on this material, tpu particles are made into films through processes such as calendering, casting, film blowing and coating. now it has been widely used in sports shoes: trademark decoration of soles and uppers, airbags, air cushions, oil bags, etc.

nowadays, there are two trends in using tpu film on sports shoes: one is a popular trend for women's sandals, which is to directly cut the highly transparent tpu film, or screen print, color or laminate it. made into mesh cloth, etc., high frequency is formed and bonded to the upper, which is functional and decorative. the second is to use waterproof and moisture-permeable tpu membranes with shoe fabrics to achieve waterproof and moisture-permeable effects.

compared with pvc, eva, butyl rubber and other plastic materials, tpu not only has excellent properties such as environmental protection, non-toxic, mildew-proof, antibacterial, wear-resistant, corrosion-resistant, biocompatibility, but also has good resistance to bending and tear, acid and alkali oil, aging and oxidation, has excellent features such as wide weather resistance. due to its unparalleled advantages, tpu film will become one of the mainstream environmentally friendly materials in the 21st century.
