TPU has been widely used in: shoes, tailors, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, leather cases, leather bags, etc.

TPU film is widely used in sports shoes: trademark decoration on sole and vamp, air bag, air cushion, oil bag, etc.Today, there are two more trends for TPU films in athletic shoes:

First, the popular trend caused by Nike sneakers is to print TPU film on screen first, then to form with high frequency and glue it on the vamp for decoration, so as to achieve special decoration effect.

The second is to use waterproof and moisture permeable TPU film and shoe material cloth to apply, in order to achieve the waterproof and moisture permeable effect.

Note during the injection molding of TPU plastic materials: The main reasons for various adverse phenomena of injection molding are as follows:

1. Due to the difference in nature of plastic raw materials,

2. Improper setting of molding conditions, such as temperature, pressure and firing rate, etc.

3. Defects in the design or production of forming molds;

4. The shape and thickness of the molding products are poorly designed.

5, injection molding machine selection is not appropriate, insufficient ability caused by, in fact, poor injection molding is not simple, is usually caused by the above factors multiple interwoven, the judgment of bad reasons depends on the operator's experience and skills. Mold filling process.Suggest when processing can consult relevant professional personnel first, in order to reduce loss cost.


Use: plastic raw materials market from our own shoes to daily necessities, to electrical appliances, automotive, aviation, satellite and other cannot leave the plastics, with the urban construction and the development of agricultural production factory, the demand of our country in terms of a single year reached 260000 tons, with industry growing demand for the need of plastic raw material with life, multinational companies and investment of polycarbonate construction industry in our country.

The main features of TPU are:

Wide hardness range: products with different hardness can be obtained by changing the ratio of TPU reaction components, and with the addition of hardness, the products still adhere to outstanding elasticity and wear resistance.

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

Outstanding cold resistance: TPU has a low glass transition temperature and still maintains good elasticity, flexibility and other physical functions at minus 35 degrees.

Good machining performance: TPU can be processed by common thermoplastic materials, such as injection molding, extrusion, calendering and so on.At the same time, TPU and some polymer materials can be processed together to obtain functional complementary polymer alloys.
