Thermoplastic PolyUrethane(TPU) Films

We Takeda Sangyo are one of the few Thermoplastic PolyUrethane (TPU) film maker in Japan.

Our Tough Grace grade TPU has high elastic like a rubber and tear-resistant.

For example, it is used as a buffer material for PC transportation. The PC is sandwiched between two thin TPU films look like wrap film and hang in a cardboard box. Our TPU film fits tightly and keep it safe during the transportation. Manufacturing thin and transparent TPU film requires highly advanced technology. We Takeda Sangyo are one of the few Thermoplastic PolyUrethane (TPU) film maker in Japan.

4 attractive things our Tough Grace grade TPU has

It is manufactured with polyethylene separator by our own method of manufacturing. Easy to process heat-sealing! Available for -30℃ to 60℃ in wide temperature range because it is strongly-designed. In addition, it has an air-barrier which means that it has variety of uses.

Recovery Rate

Each samples were stretched by 50%, 100%, 200%, 300% for each 15 mm wideness films, and the elongation to length before loading was measured when the load was freed after 5 minutes. The smaller the value, the better the recovery elasticity.

strength

④Puncture strength that can withstand even a pointed object such as a ballpoint pen.

High water-vapor permeation

⑤High water-vapor permeation, which means that outstanding moisture permeability

Air-barrier

⑥Air-barrier suitable for balloons and air buffer material

transparency

⑦transparency available for display and interior design

⑧Followingness fitting a bent face

⑨Available for -30℃ to 60℃ in wide temperature range

⑩Available for high frequency welding process As a substitute for PVC film

⑪Hard to be electrified because surface resistivity is 10¹²Ω

⑫Less thermal shrinkage. Laminatable different material such as cloth, non-woven fabric and paper.
