Outdoor Sport Clothing
Features for the zipper are high strength waterproof, explosion-proof and also high air tight.
It is coated with thermoplas:c polyurethane (TPU) on high strength
nylon woven zipper.
Two piecesof coatng material with a certain thickness are formed by
compressing each other to form an effec:ve and reliable sealing
structure, which can contribu:on to waterproof or even air tight
Compared with the CR air:ght zipper, the TPU waterproof zipper has
a serious advantage. Firstly, the TPU
waterproof zipper is light and zips smoothly; but the CR air:ght
zipper is heavier.
Secondly, the thermoplas:c proper:es of the TPU material make it
very easy to perform thermoplas:c welding
with the finished product; but the CR air:ght zipper only uses
adhesive or vulcanization and other processes.
In addition, the TPU waterproof zipper uses nontoxic and
environmental materials, which can be beLer used in
some special fields; but the CR air:ght zipper inevitably contains
some heavy metal elements.
