Thermoplastic Polyolefin (TPO) Waterproofing Membrane

Product Overview

TPO waterproofing membrane is a new - type environmentally friendly waterproof material developed by using advanced polymerization technology to organically combine ethylene propylene rubber and polyolefin. It is composed of a thermoplastic polyolefin - based polymer waterproof membrane made of ethylene propylene rubber and polyolefin as the main raw materials, and a reinforcing material layer made of glass fiber mesh or polyester felt, and is processed by advanced extrusion technology into a sheet - like flexible waterproof material. This material has excellent low - temperature flexibility, high - temperature resistance, aging resistance, and good dimensional stability. The surface is a special high - polymer - modified layer, which can significantly improve its weather resistance, crack resistance, puncture resistance, and dirt resistance. The surface of the TPO on the reinforced layer has a high - emissivity light - colored surface mainly in white, which is smooth, has high reflectivity, and does not contain harmful substances for environmental protection and construction safety.

Product Features

TPO is a new - type waterproof material formed by organically combining ethylene propylene rubber and polyolefin using advanced polymerization technology, and is a thermoplastic elastomer - based flexible waterproof membrane with both long - term durability and short - term flexibility.It has excellent low - temperature flexibility and can maintain flexibility at - 40 °C, showing good crack resistance, puncture resistance, and weather resistance.With a special formula and process, without adding any plasticizer to change the brittleness temperature, it has high flexibility and will not produce the phenomenon of general thermoplastic materials softening and deforming due to temperature rise, with stable performance.There is a layer of glass fiber reinforcement structure inside, providing excellent dimensional stability, creep resistance, puncture resistance, suitable for mechanically fixed waterproofing systems.It has excellent high and low temperature resistance, maintaining flexibility at - 40 °C and not melting at 130 °C.It has good chemical stability, resistant to acid, alkali, salt, grease, microorganisms such as bacteria, molds, and algae growth.It has good weather resistance, ozone resistance, and UV resistance, with a long service life and good stability.With light - colored surfaces such as white as the main color, smooth, high reflectivity, with effective energy - saving and anti - fouling effects.It is an environmentally friendly product, does not contain plasticizers, and the production process has no harmful gas emissions, which is harmless to the environment and human health.The joints are welded by hot air, and a high - strength and dense sealing layer can be formed.

Classification

It is classified into three types according to the product:

 

Raw material roll (code No. 1): TPO waterproofing membrane roll material without a reinforcement layer, which is a thermoplastic polyolefin waterproof membrane roll material made by using thermoplastic polyolefin as the main raw material and processed by extrusion.Glass fiber - reinforced thermoplastic polyolefin waterproofing membrane: A thermoplastic polyolefin waterproofing membrane roll material with a glass fiber mesh as the reinforcement layer in the middle of the roll material.Polyester felt - reinforced thermoplastic polyolefin waterproofing membrane: A thermoplastic polyolefin waterproofing membrane roll material with a polyester felt as the reinforcement layer in the middle of the roll material.

Scope of Application

This product is suitable for waterproofing of non - exposed roofs and exposed roofs in building external walls, and waterproofing of deformed building basements. It is especially suitable for waterproofing of light steel structure roofs and large - scale concrete structure roofs. It can also be used for waterproofing of roofs and underground projects with high requirements for environmental protection and service life.
