product description

 

Thermoplastic polyolefin (TPO) waterproofing membrane is made of ethylene, alpha olefin polymer as the main raw material, polyester fiber mesh fabric as intermediate reinforcing material, or fiber backing material, which is made by advanced extrusion processing technology. A sheet-like crimpable waterproof material.

 


 

Features

 

(1) It does not contain plasticizer, has no migration, is excellent in heat aging resistance and UV resistance, and has long-term exposure without deformation, aging, and cracking.

 

(2) Excellent tensile, tearing and puncture resistance, and strong wind resistance.

 

(3) Long-term excellent thermal welding ability, fast welding speed, high joint peeling strength (peeling strength up to twice the PVC), reliable system integrity, quick construction and convenient maintenance.

 

(4) Smooth and non-fading, pollution-resistant, chlorine-free, 100% recyclable, green and environmentally friendly.
