TPU has been widely used in: shoe materials, ready-to-wear, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, luggage, leather bags, etc.

TPU film is widely used in sports shoes: trademark decoration on soles and uppers, airbags, air cushions, oil bags, etc. Today, there are two trends in the application of TPU films on sports shoes:

One is the popular wind blown by Nike sneakers, that is, the TPU film is first screen-printed and colored, and then formed with high-frequency waves and bonded to the upper for decoration to achieve special decorative effects.

The second is to use the waterproof and moisture-permeable TPU film and the shoe material to be used together to achieve the effect of waterproof and moisture-permeable.

Attention when injection molding TPU plastic raw materials: The main reasons for the occurrence of various undesirable phenomena in injection molding are as follows: 1. The difference in the nature of the plastic material itself; 2. Improper setting of molding conditions such as temperature, pressure, and injection rate 3. Caused by defects in the design or production of the molding die, 4. Caused by poor design of the shape and thickness of the molded product, 5. Caused by improper selection of the injection molding machine and insufficient capacity. In fact, the cause of poor injection molding is not Simple, usually caused by the interlacing of the above factors. The judgment of the bad cause depends on the experience and technology of the operator. The filling process of the mold cavity. It is recommended to consult relevant professionals before processing to reduce loss costs.

Market application of plastic raw materials: From the shoes we wear to daily necessities, to electrical appliances, automobiles, aviation, satellites, etc., plastic is inseparable. The annual demand reaches about 260,000 tons. With the increasing demand for plastic raw materials in industry and life, multinational companies have invested in the construction of polycarbonate industry in my country.

The main features of TPU are:

Wide range of hardness: By changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and with the increase of hardness, the products still maintain good elasticity and wear resistance.

High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.

Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees.

Good processing performance: TPU can be processed by common processing methods of thermoplastic materials, such as injection molding, extrusion, calendering, etc. At the same time, the co-processing of TPU and some polymer materials can obtain polymer alloys with complementary properties.
