Thermoplastic polyolefin (TPO) waterproof membrane

TPO waterproof membrane is a thermoplastic polyolefin (TPO) material that combines ethylene propylene (EP) rubber and polypropylene with polymer technology as the base material, and is composed of polyester fiber mesh fabric as the carcass reinforcement , And the use of professional processing technology made of sheet curlable waterproof material. The material has both the long-term weather resistance and durability of ethylene propylene (EP) rubber and the weldability of polypropylene. A polyester fiber fabric sandwiched between two layers of TPO material can enhance its physical properties and increase its breaking strength , Anti-fatigue and anti-penetrating ability. The TPO on the upper surface of the reinforced layer has a highly reflective light-colored smooth surface mainly white, which is beneficial to environmental protection and construction safety because it does not contain chlorine.

Product description


The TPO coil material uses polymerization technology to combine ethylene propylene rubber and polypropylene. It combines the excellent weather resistance and durability of ethylene propylene rubber with the weldability of polypropylene.

Special formulation technology, no need to add any plasticizers that can make the material brittle, it can have high flexibility, and will not produce the phenomenon of general polyolefin materials becoming brittle due to the migration of plasticizers, maintaining long-term waterproof function .

A layer of polyester fiber fabric is sandwiched to provide high tensile performance, fatigue resistance and puncture resistance of the coiled material. It is suitable for mechanically fixed roofing systems.

Excellent high and low temperature resistance, still maintaining flexibility at -40 ℃, and maintaining mechanical strength at higher temperatures.

Chemical resistance, acid, alkali, salt, animal oil, vegetable oil, lubricating oil corrosion, resistance to the growth of algae, mold and other microorganisms.

Heat-resistant aging, good dimensional stability.

Light color mainly white, smooth surface, high reflectivity, energy saving effect and pollution resistance.

There is no chlorinated polymer or chlorine gas in the ingredients. No chlorine gas is released during welding and use, which is harmless to the environment and human health.

The lap joint adopts hot welding to form a high-strength sealing layer.

Scope of application

It is mainly suitable for industrial and civil buildings, public buildings and other permanent key roof waterproofing projects.

H-homogeneous coils are mainly used as flooding materials.

The L-backed coiled material is suitable for roof waterproofing systems where the base layer is fully sticky or air-laid.

P-reinforced coiled material is suitable for roofing waterproof systems with mechanical fixation or air-laid pressure items.



According to the composition of the product, it is divided into homogeneous coil (code H), coil with fiber backing (code L), and reinforced coil in fabric (code P).

1. Homogeneous thermoplastic polyolefin waterproof membrane: thermoplastic polyolefin waterproof membrane without internal reinforcement or backing material.

2. Thermoplastic polyolefin waterproof membrane with fiber backing: Thermoplastic polyolefin waterproof membrane composited on the lower surface of the coil with fabric such as polyester non-woven fabric.

3. Thermoplastic polyolefin waterproof membrane reinforced in fabric: thermoplastic polyolefin waterproof membrane reinforced with polyester or glass fiber mesh cloth in the middle of the coil.
