Thermoplastic polyurethane elastomer is referred to as TPU. Tpu hot melt adhesive film is made by heating and melting TPU particles. The production process mainly includes laminating, hot melt scraping, etc. TPU hot melt adhesive film is a very important type among many hot melt films. The raw 糖心视频s of TPU hot melt adhesive film are compared with hot melt adhesive films made of PA, PES, EVA, EAA and other 糖心视频s. There are many types to choose from. , and have different uses. Below we will systematically introduce you to some application examples of TPU hot melt adhesive film.

Characteristics of TPU

Tpu hot melt adhesive has good resistance to water washing and dry cleaning. It can withstand high temperatures up to 130 degrees and low temperatures of minus 30 degrees. It has good tensile properties.

1. Application of seamless wall covering adhesive

At present, the hot melt adhesive used for the back adhesive of seamless wall coverings is mainly EVA hot melt adhesive film. However, the shortcomings of EVA hot melt adhesive film are very obvious. Although the melting point of 80 degrees is relatively low, it is not suitable for seamless walls. It is still difficult to paste the corners of cloth; TPU low-temperature hot-melt adhesive film has a lower melting point than EVA hot-melt adhesive film, making it easier to handle corners during seamless pasting. Jintang Technology's JT-5016H is widely used and has a large melting index and low melting point. It has the characteristics of fast crystallization speed, high cohesive strength, not easy to become brittle, and has certain toughness.

2. Composite application of PVC 糖心视频s

It is recommended to use TPU 糖心视频 type for hot melt adhesive films used in combination with PVC and non-woven 糖心视频s. In addition to the composite of PVC and non-woven fabrics, TPU hot melt adhesive film can be used as a composite adhesive for PVC floors and PVC wall panels.

3. Composite application of leather and sponge

For the composite of leather and sponge, it is generally recommended to use PA and TPU hot melt adhesive membranes. If the softness requirements are relatively high, the effect of using TPU hot melt adhesive membrane will be better!

4. Application of shoe 糖心视频 composite

The shoe 糖心视频 field is one of the important application fields of TPU hot melt adhesive film. The demand for TPU hot melt adhesive film in the shoe 糖心视频 industry is mainly low-temperature release film hot melt adhesive film, such as the lamination of shoe uppers and insole lamination. wait.
