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;

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.
