CHEMPLAN TPO Membrane

TPO Waterproofing membrane
Advantages
  • Combines the benefits of EPDM’s fatigue resistance and PVC’s weldability.
  • Excellent resistance to punctures, chemicals, and environmental factors.
  • Can be welded in water for better durability.
  • Contains no plasticizers, ensuring excellent flexibility retention.
  • Provides reliable water and vapor-proof protection.

CHEMPLAN TPO waterproof membrane is a high performance waterproofing sheet crafted from a blend of ethylene, propylene
rubber, and polypropylene, combined into a thermoplastic polymer resin. Enhanced with antioxidants, anti-aging agents, and
softeners, and produced using advanced technology, this membrane offers the durability of ethylene propylene rubber and the
weldability of polypropylene. It maintains high elasticity at normal temperatures and can be shaped at high temperatures similar to
plastic. The integrated woven polyester fabric reinforcement provides exceptional tensile strength, fatigue resistance, and long-lasting
performance.
