H1：TPU film sleeve  

H2：Basic characteristics film sleeves from TPU

film sleeves from TPU - this is high quality ecologically clean material. He has like this characteristics, how high tension, high strength on stretching, percussion viscosity and rejuvenating properties. Except that, he has advantages, with which not can compare others plastic materials, including high strength, good viscosity, wear resistance, frost resistance, oil resistance, water resistance and weather resistance. B then same time he has excellent functions, such how high waterproof and moisture permeability, protection from wind, cold, antibacterial properties, protection from mold, conservation heat, sustainability to ultraviolet radiation and allocation energy. B present time he widely used in such areas, how medicine and healthcare, a also sport.

H2：Description characteristics film sleeves from TPU

H3：Wear resistance: B process operation materials often wear out from—for friction, scraping and grinding. Plastic raw materials from TPU has excellent wear resistance, more than in five times surpassing by wear resistance natural rubber. This one from preferred materials for manufacturing wear-resistant products.

H3：Features at sprain: Limit strength at sprain maybe reach 70 MPa, a relative elongation at rupture maybe reach 1000%.

H3：Strength at gap: Damage elastomers, caused expansion cracks in time application, called gap, a strength on gap determined ability material resist rupture. How rule, TPU has high strength on gap, and him strength on gap very high by comparison with some widely used rubber and plastic materials.

H3：Features bending: Many plastic materials susceptible destruction at multiple cyclical influence. Products from TPU have excellent sustainability to bending in various conditions, what does them one from the best options among polymer materials.

H3：Hydrolysis resistance: TPU materials have good water resistance at room temperature and do not undergo obvious hydrolysis within one to two years, and a series of polyester materials perform even better. The polyester series completely decomposes when soaked in water at 50°C for six months, at 70°C for three weeks or at 100°C for three to four days. This is one of the reasons why TPU is suitable as an environmentally friendly material. For products that must frequently come into contact with water, the polyether series is recommended.

H3：Heat resistance and oxidation resistance: Conventional plastic materials are susceptible to oxidation when exposed to temperatures above 70°C for a long time, but TPU has good oxidation resistance. Generally, the temperature resistance of TPU can reach 120°C.

H3：Oil resistance and chemical resistance: TPU is a highly polar polymer material with low affinity for non-polar mineral oils. It is virtually non-corrosive in fuel oils (such as kerosene and gasoline) and mechanical oils (such as hydraulic oil, motor oil and lubricating oils). Among TPU products, polyester series has the best oil resistance. TPU films and sheets have minimal volume change when in contact with oil, and their tensile strength even exceeds their original value. It should be noted that if mineral oil contains a small amount of water, it will have various negative effects on the physical properties of the film.

H3：Low temperature resistance: TPU has excellent resistance to low temperatures, typically reaching -50°C. It can replace conventional PVC, which cannot be used due to its brittleness at low temperatures, and is especially suitable for products from cold regions.

H3：Sealing: Ultra-thin TPU film sleeves are easy to be welded by high frequency or heat pressing, so they are widely used in inflatable products. Gas coefficient refers to the rate at which a gas passes through a given area of ​​a sample at a specific temperature and pressure. The gas permeability of the same material to different gases sometimes varies greatly. In general, the air tightness of polyester series products is better than that of polyester series products.

H3：Biomedical characteristics: TPU film sleeves have excellent biocompatibility, are non-toxic, non-allergenic, non-irritating to local tissue and non-pyrogenic. Therefore, they are widely used in medical and health-related products, as well as sports and protective equipment.

H2：Application areas of ultra-thin TPU film

Ultrathin film covers from TPU widely are used for manufacturing frames rehabilitation pillows, inflatable toys, equipment for water and underwater species sports, medical equipment, simulators for fitness, materials for automotive seats, umbrellas, suitcases, ready clothes, shoes and bags.

Film from TPU also widely used in production sports shoes, including branded decorations on soles and at the top shoes, pillows security and oil packages. B present time exists two trends in application films from TPU in sports shoes:​

Vo-first, under influence trend, given sports shoes Nike, on film TPU first apply colored stencil seal, then mold with with help high frequency print and glued to at the top shoes for decorations, to achieve special decorative effect.

Vo-second, waterproof and moisture permeable film TPU laminated shoe cloth for achievements waterproof and moisture-permeable effect.
