TPU composite fabric is to use TPU film to compound various fabrics to form a composite material, combining the characteristics of the two to obtain a new type of fabric.
TPU (thermoplastic polyurethanes), thermoplastic polyurethane, is a linear block copolymer composed of oligomer polyol soft segment and diisocyanate-chain extender hard segment. TPU can be salivated, blown film, calendered or coated into a film. It has the advantages of good elasticity, toughness, wear resistance, good cold resistance, environmental protection and non-toxicity.
The name of TPU composite fabric/fabric is thermoplastic elastomer rubber. This material can become soft under certain heat, while the composite fabric can remain unchanged at room temperature. It is used for more stable support on shoes. TPU composite fabric/fabric The main features are these:
Wide hardness range: By changing the ratio of each reaction component of the TPU composite fabric/cloth, tent cloth can get products with different hardness, and as the hardness increases, its products still maintain good elasticity and abrasion resistance.
High mechanical strength: TPU composite fabric/cloth products have outstanding bearing capacity, impact resistance and shock absorption performance.
Outstanding cold resistance: The glass transition temperature of TPU composite fabric/cloth is relatively low, 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 materials processing methods, such as injection molding, extrusion, calendering, etc. At the same time, TPU composite fabrics/cloths and certain polymer materials can be processed together to obtain polymer alloys with complementary properties.resistant to oil, water and mold. Good recyclability.
There are two methods for TPU composite fabrics. One is called post-attachment: the TPU film is first made into a TPU film and then glued to the fabric, and the other is online composite: the fabric is glued or not glued, and the TPU is directly salivated. The fabric is made of TPU composite fabric or mesh fabric.
Generally, the scale of post-attachment processing plants is not large. There are many small factories in China. The post-attachment process needs to add high temperature and high pressure to the TPU film again. Improper process control will cause damage to the film and even small holes.
TPU composite fabric uses: inflatable life jackets, diving bc jackets, life rafts, inflatable boats, inflatable tents, military inflatable self-inflating mattresses, massage airbags, medical anti-decubitus mattresses and professional waterproof backpacks.
