PVC film science popularization tpu composite fabric.

The tpu composite fabric of the PVC film is thermoplastic polyurethane, which 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 thin film, with excellent elasticity, toughness, abrasion resistance, good cold resistance, environmental protection and non-toxicity. There are two methods for TPU composite fabrics. One is called post-attachment: the TPU film is 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 factories is not large. There are many small factories in China, most of which buy TPU film from outside film factories, and only complete the process of gluing and laminating. The process of post-attachment requires high temperature and high pressure to be applied to the TPU film again. Improper process control will cause damage to the film, and even small holes.
