3.Types of TPU membrane:
The TPU membrane is an environmental protection product,non-poison and non-pollution.At present,it belongs to one of the highest technical product in the same category of the world.The different sorts of the products made of it are well received by the vast consumers both at home and abroad,and will be more and more popular in the future. |
