TPU paste the official name should be called TPU composite fabric or laminated fabric. That is, the two fabrics or more is a film and fabric together with the advantages of both the new fabric.

At present the most popular and most environmentally friendly concept of the paste is the TPU composite fabric, is to use TPU film composite in a variety of fabrics to form a composite material, combined with the characteristics of the two get a new fabric.

TPU (Thermoplastic polyurethanes), a thermoplastic block polyurethane, is a linear block copolymer consisting of oligomeric polyol soft segments and diisocyanate-chain extenders. TPU can be saliva, blown film, calendering or coating made of thin film, with good elasticity, toughness, wear resistance, good cold resistance, environmental protection, non-toxic superior characteristics.

TPU composite fabric has two practices, one called post-paste: first made of TPU film and then glue with the fabric, the other called online composite: coated with plastic or not on the plastic, directly to the TPU salivation in the Fabric made of TPU composite fabric or folder mesh.

Generally do post-processing factory scale is small, there are many small factories in the country, mostly from the outside of the thin film factory to buy TPU film, itself only finished glue on the process. Post-paste the process to the TPU film again high temperature and high pressure, improper process control will damage the film, or even small holes.

On-line bonding is a fluid TPU film one-time composite in the fabric, to avoid the damage to the film, the surface forming beautiful, and can make different lines. But this composite mode of equipment investment, high technical requirements. China can do this composite technology manufacturers very few, most of them in Taiwan, South Korea and other places to produce.

As we all know, TPU pollution-free problem, up to environmental standards, so its high-strength composite products are equipped with light, high strength and anti-aging characteristics. TPU fit with the above characteristics, more waterproof, air tightness, easy to high frequency processing and other characteristics. Applicable to diving lifesaving equipment, mountaineering outdoor sporting goods, health care equipment, military supplies, inflatable tents, hot-pressing waterproof backpack, luggage luggage, shoes and other products.
