Explain the characteristics of TPU film

1. Yellowing resistance

The yellowing is mainly due to the yellowing of the color of the TPU film due to continuous ultraviolet radiation. There are various inspection standards for yellowing resistance, and the main factors include UV wattage, irradiation distance, time, temperature and humidity.

2. Rebound performance

The deformation resilience of the TPU film is mainly a feature of the TPU film's immediate recovery after being deformed by an external force.

3. Deformation and elasticity

The deformation and resilience of the TPU film are the degree of deformation per unit volume of the sample under vertical pressure, and the speed and degree of resilience after the pressure is released reflect the compressive resistance of the material.

4. Tearing resistance

The tear resistance of the TPU film refers to the notched tensile tear resistance. The tear resistance of TPU film reflects the transverse physical properties of different materials, with different tear strength and tear angles, as well as different tear standards.

What is the difference between TPU film and other materials?

What is the difference between PVC film and TPU film? At present, there is no more waterproof and breathable fabric on the market than PTFE, PU or TPU, but you will see many names and registered fabric brands of various brands. TPU film manufacturers have a variety of fabric styles, or produce them according to the requirements of the brand owners, but they generally buy from various fabric manufacturers. Because these fabric manufacturers may not have their own branded fabrics, they have registered their own fabric brand as a promotional point. First understand whether the fabric is PTFE or TPU.

TPU raw materials belong to environmentally friendly plastic materials. According to different main uses, the requirements for material characteristics are also different, so TPU is also divided into many types. The universal scope of application can basically be used in all aspects, only wanting, and basically no guarantee.

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.
