TPU hot melt adhesive film has higher scissor tear resistance and tensile working strength

    TPU hot melt adhesive film is a kind of material with the characteristics of washing and dry cleaning, it can withstand the low temperature of minus 20 degrees and the high temperature of 110 degrees, and has good stretchability and softness. It has a wide range of hardness, and it still maintains good rubber elasticity and elongation even at high hardness.

    Compared with rubber materials,TPU hot melt adhesive film has higher scissor tear resistance and tensile working strength, especially under high hardness. And, compared with plastics, it has higher impact strength and bending structural strength requirements. Therefore, TPU hot melt adhesive film is a very strong and durable material.

    High adhesive strength is the core performance of TPU hot melt adhesive film, especially in the occasions that bear large structural stress. If you want to apply TPU hot melt adhesive film to occasions with high strength requirements, you must increase the adhesive strength. In order to achieve high bonding strength, TPU hot melt adhesive film needs to have strong polarity and good wettability. Since the hot melt adhesive has no solvent, its fluidity and wettability are poor, so improving the bonding strength of the TPU hot melt adhesive film needs to start with increasing the polarity and wettability.

    TPU hot melt adhesive film has better elasticity, especially in the bonding of elastic materials. In addition, it is also waterproof, so it is widely used in TPU hot melt adhesive films in products that need to be washed, especially in the field of clothing. TPU hot melt adhesive film material is also very soft, very suitable for fabric bonding and integration in the clothing industry, soft to the touch, without irritation and foreign body sensation.

    In the future, we may further increase the speed of TPU hot melt adhesive film to expand this advantage. It is mainly achieved by accelerating the hardening speed, improving the thermal viscosity, reducing the specific heat of the material and optimizing the equipment.

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.
