We should know these characteristics of TPU film

    You should know these performance characteristics of TPU film, because customers often ask!

    Understanding the performance of TPU film is not to make it bigger, but to be more professional and win the trust of customers!

    Transparent effect of TPU film

    The transparency of the TPU film refers to the ability of the natural color test piece to achieve intuitive clarity at different thicknesses, and the thickness is often used to evaluate the effect of the transparent TPU film.

    TPU film yellowing resistance grade

    The yellowing is mainly due to the yellowing of the color of the TPU film due to continuous ultraviolet radiation. The laboratory simulated yellowing test generally judges the color change with a grade of 1-5, and grade 5 means no change.

    There are many detection standards for yellowing resistance, the main factors are UV wattage, irradiation distance, time, temperature and humidity.

    Usually, our company has two anti-yellowing materials to choose from: 1st grade, 4-4.5 grade TPU film and 5th grade aliphatic TPU film.

    TPU film has excellent mechanical properties, such as high strength, high elasticity, high wear resistance and high flexibility, as well as oil resistance, solvent resistance and general chemical resistance, which determines that TPU has the characteristics of multi-purpose, mainly used in Target materials, adhesives, pipes, films and other fields.

    TPU film has excellent characteristics such as high strength, high toughness, wear resistance, oil resistance, cold resistance, aging resistance, environmental protection, non-toxicity, and degradability, which are unmatched by other plastics and rubbers. It also has excellent properties such as waterproof, moisture permeability, wind resistance, cold resistance, antibacterial, and ultraviolet resistance, and can be used in many industrial and civil fields. It is a green film and an ideal substitute for PVC film.

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.
