TPU film is not resistant to strong solvents and strong acid and alkali media

    TPU film has good low temperature resistance, usually can reach -40 degrees Celsius, is a good substitute for PVC, TPU film has good biocompatibility, non-toxic, no allergic reaction, no stimulation, so it is widely used in medical treatment , hygiene and other related products as well as sports and protective equipment.

    TPU film has the characteristics of high strength, wear resistance, environmental protection, and easy processing; it is suitable for lamination, hot pressing, high frequency, and other processing methods. Our film: its thickness is usually between 0.015mm-5.0mm, and its width is generally between 80cm-160cm; according to the different needs of customers, its thickness, width, color, surface effect and texture can be adjusted. According to the special needs of customers, the physical properties of TPU film are directional improved;

    The hardness of the TPU film is 60A-75D. When the hardness is above 85A, the elongation ability is still maintained, which is an advantage that some other elastomers do not have. Therefore, the TPU film has a high load supporting function and excellent water absorption and drainage effects; the TPU film is not only a high-pressure anti-aging material , is also an environmentally friendly material, which is very suitable for the needs of contemporary customers. TPU film products have very unstable characteristics in the production process, and development and testing require very advanced technology and equipment. On the other hand, due to the competition of other materials, economic factors also make the production of TPU film must be more efficient, and can repeatedly produce high-quality TPU film to reduce costs. At the same time, it also requires a wider variety of TPU films, thinner and thicker, Introduce better high technology to improve its physical performance, so as to obtain higher added value

    Chemical resistance of TPU film. TPU film is not resistant to strong solvents and strong acid-base media. At a certain temperature, alcohols, acids, and ketones will swell and degrade polyurethane elastomers. Dichloromethane, trichlorethylene, etc., solvents will swell the TPU film at room temperature

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.
