How to choose the tpu hot melt adhesive film that suits you

    First, you need to know what material you need to bond. The adhesion fastness of tpu hot melt adhesive films at different temperatures to different materials is different. No single adhesive adheres to all materials better than all others. For example, the fastness of tpu hot melt adhesive film to textile fabrics is very strong, while the adhesive strength to PE plastic is almost zero;

    The high and low temperature of the tpu hot melt adhesive film is the high and low temperature of the melting point. Low temperature tpu hot melt adhesive film refers to low melting point tpu hot melt adhesive film. If your material's maximum temperature resistance cannot exceed 100, then you should choose a melting point lower than tpu hot melt adhesive film, because if the processing temperature does not reach the melting point of the glue, the adhesion is almost zero. The tpu hot melt adhesive film can be a tpu hot melt adhesive film with a melting point of 65, which can reach low temperatures.

    At what temperature the fusion bonding effect of tpu hot melt adhesive film is better, the key is to look at the temperature resistance of the bonding material, and then select and determine the specifications and characteristics of the tpu hot melt adhesive film to be used according to the requirements of material compatibility. Through these two dimensions, you can basically determine whichtpu hot melt adhesive film to use, so the proofing test is very important!

    If it can meet your bonding requirements, choose the thinnest tpu hot melt adhesive film (the thinner the tpu hot melt adhesive film, the cheaper the price). Release paper tpu hot melt adhesive film can be called tpu hot melt adhesive film with substrate, and the substrate can be divided into release paper and release film. The release tpu hot melt adhesive film with substrate is mainly used for materials that require secondary lamination, which looks like a plastic film.

    Advantages of tpu hot melt adhesive film bonding

    1. Strong double-sided tape

    2. Environmentally friendly, non-toxic and solvent-free.

    3. High flexibility and water resistance

    4. The tpu hot melt adhesive film has high elasticity and recovery, abrasion resistance and folding resistance

TPU hot melt adhesive film vs anaerobic adhesive: "Scene flexibility" difference in automotive interior bonding
2025-09-11
​From the perspective of curing conditions, TPU hot melt adhesive film does not need to rely on special environments, while anaerobic adhesives are severely restricted by "auerobicity". The curing principle of anaerobic glue is to undergo polymerization under conditions of lack of oxygen and catalyzed by metal ions (such as iron and copper). If it is in an environment where air circulation or metal substrates are not available, the curing speed will be greatly slowed down or even unable to cure. In automotive interiors, most bonding scenarios are "open" (such as bonding the door panel skin to PP substrate, and the ceiling fabric to the sponge), the air can freely contact the bonding surface, and the substrate is mostly non-metallic (PP, ABS, fabric, etc.), lacking metal ion catalysis, and additional catalyst is required when using anaerobic glue, and the curing time is as long as several hours, which is difficult to meet the needs of industrial production. The TPU hot melt adhesive film only needs to be melted by heating (120-160℃) and can be cured after pressurization and cooling. It does not need to rely on the ambient oxygen concentration or the base material. It can be cured stably in open or closed bonding scenarios, and the curing time only takes a few dozen seconds to a few minutes, adapting to the fast-paced needs of the interior production line.
