Product Detail
TPO waterproof membrane,Polyolefin thermoplastics waterproof material 1>Weather resistance and durability; 2>Excellent weld TPO waterproof membrane,Polyolefin thermoplastics waterproof material

Description

TPO is a waterproofing sheet, consisting of thermoplastic polyolefin compound resin materials as the base stock, reinforced with polyester mesh fabric. There have two kinds of thickness: 1.2mm and 1.5mm.

Where to use

1>Various roofing waterproof projects, such as industrial and civil buildings, public constructions;

2>Mechanically attached waterproofing system.

Advantages

1>Weather resistance and durability;

2>Excellent weld ability;

3>No any crisp agents to prevent materials brittleness;

4>Intermediate enhanced polyester mesh fabric to have high tensile strength, fatigue resistance and penetrating resistance suitable for mechanically attached roofing systems;

5>Excellent the same high and low temperature resistance as rubber materials which can keep  flexible at -50° C and keep mechanical strength in high temperature;(-60° C----130° C)

6>Excellent chemical resistance to acids, bases, and restaurant exhaust emissions;

7>Dimension stability;

8>White-based light-color and smooth surface with high reflection, energy saving and anti-dust functions;

9>Use heat welding for the seam areas to form a reliable seamless waterproof layer.
