Product Description

ermoplastic polyolefin (TPO) membrane is a type ofpolymer waterproof material based on polypropylene(PP) and rubber, prepared byexisting technique. It is recycling throughout itsservice life (from its production till the end of its service life). There isno chlorine, heavy metal nor elements harmful to the roots and it isenvironmental friendly. 

PRODUCT FEATURES

1. Excellent weather resistance, aging resistance, tensile strength and elongation.

2. Operation can be done on wet substrate. Directly expose to the weather conditions without any protective layer. Simple construction. No contamination.

3. Repeat welding is possible.  

4. White color TPO to increase reflection of sun rays.

5.Ability of resist the growth of mould and alga.


WHERE TO USE

Mainly apply to the roofwaterproofing construction of industrial, civil and public buildings.

Membranereinforced with mesh ( TPO-P) is applied to the single ply roof waterproofsystem by mechanical fastening.

Membrane withunderlying layer of fabric ( TPO-L) is applied to the concrete substrate byfull adhesion waterproof system.

Homogeneousmembrane (TPO-H) is applied to the flashing area.
