TPO Waterproofing Membrane

PRODUCT INTRODUCTION

TPO waterproof membrane is a type of excellent capacity waterproof sheet combines ethylene, propylene rubber and polypropylene into a thermoplastic polymer resin as its main material, and mix together with antioxidants, antiager and softener, then by manufactured with advantage technology.

This product has both ethylene propylene rubber’s excellent weather ability and polypropylene’s weld ability, which can show high elasticity in normal temperature, and can be shaped in high temperature like plastic. The middle woven polyester fabric reinforcement can provide the membrane with high tension ability, fatigue resistance and durability performance

PRODUCT FEATURES

1.        TPO membrane has combine the advantages of EPDM and PVC. With the EPDM ’s fatigue ability and PVC’s weldable ability.

2.        Great resistance to puncture, chemical and environment.

3.        Compare to EPDM, TPO with better puncture resistance, can be welded in water and with better  durability.

4.        No plasticizer exist, so the flexibility retention rate is excellent.

APPLICATION PROCESSES

1.        Pay off: Pre pave the membrane according to the site situation. If pave on the profiled steel roof, The pave direction should be vertical to the direction of steel sheet. Fix the membrane with design tools, cut the membrane if necessary

2.        Use welding gun or machine to weld the joints according to the relevant standards and rules.

3.        After large area construction, do a special extra fixation and sealant around the deformation joints, skylights and out-roof area.

PRODUCT MODEL

According to product components can be divided into homogeneity membrane (H), membrane with fiber backings (L) and Fabric covert reinforcement membrane (P).

NOTES

1.        The material of the welding place should be clean without water drop, oil and dust.

2.        Before official welding should do the pre-welding test, to make sure the welding temperature and speed.
