Product Details

★Product Description

Thermoplastic polyolefin (TPO) waterproofing membrane is a kind of ethylene resin as the base material, the use of advanced polymerization technology and a specific formula made of sheet thermoplastic rubber elastic waterproof material, is popular in the United States and Europe in recent years, a new material, the ingredients do not contain plasticizer, there is no plasticizer migration and brittle. It has the comprehensive characteristics of high tensile strength, good wear resistance, strong UV resistance, smooth surface, high reflectivity and pollution resistance. Easy to process, can be welded, convenient construction, completely recycled, green new waterproof material.

☆Features:

Using advanced polymerization technology and special formula, without any plasticizer, to maintain long-term weather resistance;

With high tear strength, breaking strength and puncture resistance;

Through thermal welding can form stronger than the coil seam, welding seam surface is smooth, continuous and uniform;

The gray and black bottom reinforced coil has high reflectivity. The coil does not contain chlorinated polymer and chlorine gas, which is conducive to environmental protection and construction safety.

★Product types and specifications

According to the classification of products, it is divided into: homogeneous non-composite coil (code H), composite coil with fiber backing (code L), and reinforced coil in fabric (code P)

Length: ≥ 20 m Width: 2.0 m

Thickness: 0.5mm 1.0mm 1.2mm 1.5mm 2.0mm

Color: black, white, green, etc., can be customized according to customer requirements (two-color coil can also be customized).
