​TPU film structure surface problem analysis The chemical reaction solvent system deals with the surface information of TPU film. The TPU film manufacturer understands the solvent treatment of different chemical industries, such as wiping and coating. The TPU film​ is not only suitable for all kinds of fabrics, but also can produce products with clear shape and stable size by vacuum thermoforming. TPU is a kind of strong polar polymer material, while non-polar mineral oil has a very low affinity, and is almost impervious to corrosion in fuel oil and mechanical oil. TPU film and polyester TPU film have good oil resistance. TPU is very easy to melt at high frequency or under hot pressure, so it is widely used in inflatable products.

    There are two trends in the application of TPU film on sports shoes: one is the popular trend caused by women's sandals, that is, the highly transparent TPU film is directly cut, or screen printed and colored, or the binding cloth is based on a sandwich cloth, etc., which is formed and bonded on the upper with high frequency, with functional and decorative effects. The second is to use the waterproof and moisture permeable TPU film and the shoe material cloth to achieve the waterproof and moisture permeable effect

    At present, there are more than 100 domestic TPU film wholesale manufacturers, and there is a certain gap between the stability and coverage of products and those of foreign companies. The first reason is that the products in process do not have technical advantages, the second reason is that the precision of the equipment is not enough due to the use of domestic devices, and the third reason is that the stability of domestic raw materials is relatively poor. In the application of future emerging fields, biomedicine is a potential important application field of polyurethane elastomer. Polyurethane elastomer can be used to synthesize medical heart bridging, suture and other materials with good physical and mechanical properties by selecting appropriate soft and hard segment structure and proportion. Its wear resistance, toughness and biocompatibility are good, and its degradation cycle in vivo is short. Compared with other polymer materials, polyurethane elastic materials are more suitable to be made into scaffolds in tissue engineering or used in the manufacture of human organs, such as artificial heart and cardiac auxiliary devices. The materials themselves have the properties of not causing thrombus and immune response of human body, not causing cancer and having good biocompatibility. In recent years, this material has been widely used in the preparation of artificial heart and artificial skin.

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.
