tpo roofing membrane

Products Description

Thermoplastic Polyolefin (TPO) roofing 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.

Product Feature

1.High UV-resistance and high reflectivity

2.Excellent weathering characteristics and long-term flexibility

3.High tensile strength and puncture resistance

4.Excellent resistance to harsh chemicals and industrial pollutants

5.Heat or solvent-welding effectively provides seamless roof coverings


1. TPO waterproofing membrane of homogeneous or non-lamination (code H)

2.TPO waterproofing membrane utilizing a fabric backing or lamination (code L)

3.TPO waterproofing membrane with internally reinforcement fabric(code P)

4.TPO waterproofing membrane with reinforcement of fiberglass and nonwoven (code G)

5.TPO waterproofing membrane which utilizing a fabric backing and with reinforcement of fiberglass and non woven(Code GL)


Widely used in waterproofing engineering such as roof, basement , water conservancy, dam,tunnel, supermarket and workshop etc.
