What material is tpu?
Tpu is the abbreviation of thermoplastic polyurethane, and its Chinese name is thermoplastic polyurethane elastomer. This is a building material, in fact, it is also a common material. Tpu has strong high tension and high tension. It is a mature environmental protection material and has passed the international environmental protection material certification.
Characteristics of tpu material:
1. High wear resistance: It can be seen from the comparison of Taber wear index between tpu and other materials.
2. Wide hardness range: By changing the ratio of TPU reaction components, products with different hardness can be obtained, and with the increase of hardness, the products still maintain good elasticity.
3. High mechanical strength: tpu products have outstanding bearing capacity, impact resistance and shock absorption performance.
4. Good processability: tpu can be processed by common processing methods of thermoplastic materials, such as injection, extrusion and calendering. At the same time, TPU can be processed with some polymer materials to obtain polymer alloys with complementary properties.
5. Outstanding cold resistance: The glass transition temperature of tpu is relatively low, and it still maintains good physical properties such as elasticity and flexibility at MINUS 35 degrees.
6. Oil resistance, water resistance and mildew resistance.
7. Good recycling.
Tpu products are widely used:
A. Footwear: sports shoes Logo, sports shoes air cushion, hiking shoes, snow shoes, golf shoes, roller skates, fabrics and internal bonding materials.
B clothing: snow coat, raincoat, windbreaker, cold jacket, field suit, diaper, trousers and other composite fabrics (waterproof and moisture permeable).
C. Medicines: surgical gowns, hats, shoes, hospital mattresses, ice packs, bandages, plasma bags, surgical dressing belts, masks and other fabrics and lining materials, operating bed airbags.
D defense supplies: fabrics and lining fabrics of aircraft fuel tanks and airbags, weapon sealing films, tent windows, military water bags, life jackets, inflatable boats, etc.
E. Sporting goods: football surface and liner, inflatable bed, drinking bag, ski gloves (waterproof bag), diving suit, snow suit, swimsuit, snowboard, trademark, airbag, undershirt, slimming suit and other fabrics and lining materials.
F Industrial supplies: rubber edges of trumpet drum paper, waterproof strips, sound insulation materials, fireproof materials, fireproof clothing, finished fireproof clothing, fireproof cloth and other fabrics and inner composite materials.
G. Other uses: mobile phone keys, plastic inflatable toys, bed sheets, table towels, shower curtains, furniture cloth, aprons, pianos, computer keyboards, film-coated fabrics and lining materials.
The above is the introduction of tpu, which is a new type of environmental protection material. I hope the above introduction can help you know more about what tpu is, its characteristics and applications.
