today i will take you to learn about tpu film composite fabrics

tpu composite fabric is a composite material formed by using tpu film on various fabrics. it combines the characteristics of both to obtain a new type of fabric.

TPU(thermoplastic polyurethane), thermoplastic polyurethane,tpu filmit is a linear block copolymer composed of oligomer polyol soft segment and diisocyanate chain extender hard segment. tpu can be cast, blown, calendered or film-coated, and has good elasticity, toughness, wear resistance, cold resistance, environmental protection and non-toxicity.

the name of tpu composite fabric/cloth is thermoplastic elastomer rubber. the material softens under a certain amount of heat, while the composite cloth remains unchanged at room temperature. support for stabilizing shoes.

the main features of tpu composite fabric/cloth:

wide range of hardness: by changing the proportion of the reaction components of tpu composite fabric/cloth, tent cloth can obtain products with different hardness, and as the hardness increases, its products still maintain good elasticity and wear resistance.

high mechanical strength: tpu composite fabric/cloth products have excellent load-bearing capacity, impact resistance and shock absorption properties.

excellent cold resistance: tpu composite fabric/cloth has a lower glass transition temperature, and the canvas factory still maintains good elasticity, flexibility and other physical properties at minus 35 degrees.

good processing performance: tpu composite fabric/cloth can be processed by common thermoplastic material processing methods, such as injection molding, extrusion, calendering, etc. at the same time, the co-processing of tpu composite fabric/cloth with certain polymer materials can obtain polymer alloys with complementary properties.

tpu filmoil, water and mildew resistant. good recyclability.

there are two ways to use tpu composite fabrics

one is called post-adhesion: the tpu film is first made and then bonded to the fabric, and the other is called in-line lamination: glue is applied to the fabric or not, and then the tpu is cast directly on the fabric to make tpu composite fabric or mesh.

typically, attached treatment plants are small in size. there are many small factories in china. most of them buy tpu film from outside film factories and only complete the process of gluing and lamination. during the post-adhesion process, high temperature and high pressure are applied to the tpu film again.tpu manufacturerimproper process control will damage the film and even create small holes.

in-line lamination is to laminate the liquid tpu film on the fabric at one time to avoid damaging the film, form a beautiful surface, and can be made into different threads. however, this composite method requires substantial equipment investment and high technical requirements.

tpu composite fabric uses: inflatable life jackets, diving bc jackets, life rafts, inflatable boats, inflatable tents, military inflatable self-inflating mattresses, massage air bags, medical anti-decubitus mattresses and professional waterproof backpacks.
