Thermoplastic Polyolefin (TPO) Waterproofing Membrane
glass fiber reinforced (TPO-G)
Products Description
The Thermoplastice Polyolefin (TPO) waterproof membranes are the most popular waterproof materials in the world at present. It’s thermoplastic elastomeric waterproof materials by adopting advanced polymerization together with squeeze technology,which perform well in mechanical properties, high tensile strength,oxidation-resistance and resistance to puncture.
