Information

TPU is different from polyurethane foam in rigidity and soft foam in resilience. TPU has the elasticity of rubber and the strength of plastic. TPU was synthesized from polyol, isocyanate and small molecule chain extender. Polyols give TPU elasticity and isocyanates give TPU strength.

TPU is widely used because of its special performance.

 

Footwear material: TPU is wear - resistant and elastic, suitable for athletic shoes and casual shoes sole. In EVA, rubber, PVC and other numerous sole materials occupy a place. Nike adds transparent TPU air cushion to the middle and bottom part of the sports sole to produce professional sports shoes with stronger functionality. Besides the elasticity of TPU, high transparency also makes the sole more beautiful and high-end. Heel of shoe and head of shoe, have fixed and support action to have certain hardness place is called Harbor treasure. The traditional Gangbao USES TPU sheet material for cutting, but the current hot-melt adhesive-type Gangbao is more convenient to use and more efficient in shoe making. Some colorful TPU accessories and elastic TPU shoelaces on the vamp are also widely used in TPU.

Pipe: TPU has high physical strength, and TPU pipe is the best choice for pneumatic pipe. The pressure of pneumatic equipment and tools is usually around 8kg, while TPU pneumatic tube can generally bear more than 30kg. In addition, TPU is resistant to oil and chemicals and can be used as military field pipelines and oil sacs.

Wire and cable sheathing: Wire and cable sheathing protects the wire from weather effects such as rain, sunlight and physical damage such as scraping. Traditional wire and cable sheaths are made of PVC or rubber. Due to its tear resistance, abrasion resistance and high and low temperature resistance, TPU is replacing more and more PVC or rubber. Due to the high cost of TPU, TPU has been widely used in backbone wires at present.

Thin film: The biggest characteristic of TPU thin film is waterproof breathability, it is used in textile and garment. The fabric of the blazer and outdoor sportswear is combined with TPU film. The down jacket is made of TPU composite fabric with puncture resistance and no down will come out. It is worth mentioning that TPU can be biodegradable, far better than PE film and PP film in terms of environmental protection and recycling, and will not bring white pollution.

Medical care: The key requirements for the medical profession to make materials include safety and no release of potentially hazardous substances. TPU is just fine. The flexibility of TPU does not need to be obtained through plasticizers, and there is no risk of phthalates migrating from medical devices to the liquid or human body. Nowadays, TPU has been applied to infusion tubes and medical devices. Some leading TPU manufacturers are also conducting TPU research on the use of human implant materials.
