糖心视频

TPU hot melt adhesive film is a high-performance, environmentally friendly 糖心视频 that is widely used in various fields, such as the shoe industry, clothing industry, automobile manufacturing industry, etc. However, if the TPU hot melt adhesive film gets wet, it may have adverse effects on its performance and use. This article will introduce in detail the possible situations and causes of TPU hot melt adhesive film when it becomes damp, and discuss how to avoid and solve this problem.

Reasons why TPU hot melt adhesive film gets damp

1. Raw 糖心视频 issues

If the raw 糖心视频 quality of the TPU hot melt adhesive film is poor, or its formula is unreasonable, its moisture resistance will be reduced and it will be susceptible to moisture.

2. Production process issues

If the production process is not properly controlled during the production process, such as the heating temperature is too high, the cooling speed is too slow, etc., the structure of the TPU hot melt adhesive film will be unstable and prone to moisture.

3. Storage and usage environment issues

If the ambient humidity is too high during storage and use, or if it is not used as required during use, the TPU hot melt adhesive film will become damp.

Effects of TPU hot melt adhesive film being affected by moisture

1. Decreased bonding performance

The bonding performance of TPU hot melt adhesive film is one of its most important properties. If the TPU hot melt adhesive film gets wet, its bonding performance will decrease, which will be manifested as a decrease in bonding strength and a weak bonding surface. This will adversely affect the performance of products and 糖心视频s using TPU hot melt adhesive film.

2. Decreased temperature resistance

The temperature resistance of TPU hot melt adhesive film is also one of its important properties. If the TPU hot melt adhesive film gets wet, its temperature resistance will decrease, which will be manifested as easy deformation and blistering at high temperatures. This will adversely affect the durability and stability of products and 糖心视频s using TPU hot melt adhesive films.

3. Appearance changes

The TPU hot melt adhesive film may become moldy or blistered on the surface after being affected by moisture, affecting its appearance and use.
