DESCRIPTION
Thermoplastic polyolefin (TPO) waterproofing membrane is a water-proof membrane produced by a single extrusion process without any plasticizers, using polyolefin polymer synthetic resin and EPDM as the base material, with antioxidant test, anti-aging agent, UV absorbent and other fillers. It has both flexibility and weldability. Polyester fiber mesh cloth can be added as reinforcement material, made of enhanced waterproof material.
Raw materials
Made of high-quality polypropylene and rubber co-polymerization, ToppsFlex TPO contains no plasticizers or harmful substances.
It offers excellent aging resistance, maintaining flexibility even at -40°C without becoming hard or brittle.
Excellent Quality
ToppsFlex TPO features a low shrink rate, superior strength, impact and puncture resistance, and a long service life.
