Industry Information

thermoplastic polyurethane elastomer (tpu) is an anbm type block copolymer. there are urethane groups and polyether groups in tpu. carbamate groups have higher cohesive energy and clump together to form hard segments, whereas polyester or polyether groups clump together

the principle of tpu waterproof and breathable membrane is: in the state of water vapor, the water vapor particles are very small, much smaller than the diameter of the pores of the waterproof breathable membrane. according to the principle of capillary movement, it can penetrate well from the inside to the capillary to the outside, thus allowing vapor permeability to occur. phenomenon. when water vapor condenses into water droplets, the particles become larger. due to the tension on the surface of the water droplets...

tpu spray-free adhesive blister film, as the name suggests, is an adhesive film that does not require spraying. it is a type of tpu hot-melt adhesive film. so where is this new product - spray-free glue used? let me introduce it to you below! tpu spray-free glue can be made into a composite hot-melt adhesive film. the composite hot-melt adhesive film is produced from environmentally friendly tpu materials...

the market demand for low-temperature hot-melt adhesive films is still relatively large. for example, the shoe material industry, wall covering industry, plastic products and other industries all have relatively large demand for low-melting point hot-melt adhesive films. however, everyone does not know much about low-melting point hot-melt adhesive films, and most of them are limited to eva low-temperature hot-melt adhesive films. low temperature hot melt adhesive...

the quality of tpu composite waterproof membrane is stable. tpu waterproof and breathable membrane is an important product of fulian in clothing wash-resistant composite. washable composite clothing can save people a lot of trouble in their daily lives. whether it is winter or summer, hot or cold water, it can be easily washed, saving a lot of trouble...

the quality of tpu films can be distinguished from the following aspects: 1. transparency: the higher the transparency of the tpu film, the better the quality. the quality can be judged by comparing the transparency of tpu films of different brands with the same thickness. ⒉ thickness: the more uniform the thickness of the tpu film, the better the quality. you can use a thickness gauge to test whether...

tpu hot melt adhesive film is a kind of hot melt adhesive film, which is mainly used for bonding in textile, leather, printing, automotive interiors, clothing and other fields. the method of using tpu hot melt adhesive film is as follows: 1. select appropriate hot melt adhesive equipment, such as hot melt adhesive machine, hot air gun, etc. 2. cut the tpu hot melt adhesive film to the appropriate size and proceed as needed...

tpu glue-free plastic blister film is widely used in the furniture industry and is mainly used for surface covering and protection of furniture. the following are some specific application scenarios: 1. furniture surface protection: tpu spray-free blister film can be used to protect the furniture surface, which can effectively prevent the furniture surface from being scratched, worn, polluted, etc., prolonging...

the breathable performance of tpu waterproof breathable membrane depends on its specific manufacturing process and material composition. generally speaking, tpu waterproof and breathable membrane has good breathable performance, which can effectively prevent the accumulation of water and steam under the membrane while ensuring waterproof performance, and maintain human body comfort. the breathability performance of tpu waterproof breathable membrane is mainly...

tpu hot melt adhesive film is a hot melt adhesive film made of thermoplastic polyurethane (tpu). it is a hot melt adhesive material that can be melted by a hot melt adhesive machine and then applied to the substrate. the tpu hot melt adhesive film has the following advantages: 1. good bonding performance...
