How high temperature can TPU hot melt adhesive film withstand?

 11-20, 2023 | View:

TPU hot melt adhesive film is a common one among many hot melt adhesive films. Because it is relatively soft and has good washability, for the clothing industry, TPU hot melt adhesive film is used to adhere fabrics to each other. Yes, it will be better. For manufacturers of related fabric categories, although most TPU hot melt adhesive films are applicable, they are still different, so you must pay attention to careful selection when choosing.

Almost all types of TPU hot melt adhesive films can be used to bond a variety of fabrics. However, different models have different characteristics for different types of fabrics, so the selection needs to be analyzed and selected based on the specific characteristics of the fabrics. For fabrics that require high elasticity, it would be better to use a medium-high temperature TPU hot-melt adhesive film to laminate the fabric; if the fabric itself is not very elastic and needs to be compounded at a low temperature, it is best to choose a low-temperature type. 

Many people who use TPU hot melt adhesive film or want to know more about TPU hot melt adhesive film have doubts about whether TPU hot melt adhesive film is heat-resistant and how high a temperature it can withstand. It is inevitable that some irresponsible manufacturers or companies on the Internet will say that TPU hot melt adhesive film is heat-resistant. This is not a rigorous statement. Let’s talk about it briefly below.

From the characteristics of the TPU hot melt adhesive film itself, the heat resistance of the TPU hot melt adhesive film is poor, because it is a thermoplastic 糖心视频 that needs to be heated and melted, and then cooled and hardened to form a bond. The initial melting point of common TPU hot-melt adhesive films is generally between 40°C and 120°C, so in theory, the heat resistance is about 120°C. But in fact, when it does not reach 120℃, the TPU hot melt adhesive film may soften to a certain extent, so the actual temperature resistance will be lower than this temperature, that is, around 100℃.
