Description
It is based on polypropylene and rubber by using state-of-the-art polymer manufacturing technology. This technology enables TPO membranes flexible at low temperature without the use of polymeric or liquid plasticizer.
Feature & Benefit
1. High puncture and rooting resistance, especially suitable for planting roof system.
2. Easy installation and hot-air welding seam, environmentally.
3. High tensile strength and elongation, size stability.
4. Good plasticity, convenient for detailing and corners treatment.
5. Excellent performance in aging resistance, service life of 20 years for exposed use, and 50 years for non-exposed application.
Main Application
Mainly apply to the roof waterproofing construction of industrial, civil and public buildings.

Application Guidance
Membrane reinforced with mesh ( TPO-P) is applied to the single ply roof waterproof system by mechanical fastening.
Membrane with underlying layer of fabric ( TPO-L) is applied to the concrete substrate by full adhesion waterproof system.
Homogeneous membrane (TPO-H) is applied to the flashing area.
