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
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.
