Waterproof material compound PVC waterproof membrane
1. Good c ombination of high elasticity and tensile strength.
2. Fine resistance to stactic electricity
3. Excellent resistance to ageing and weathering
4. Durable: If the pvc membranes used on exposed surfaces,the effective age can be more than 20 years.If the pvc membranes used on no-exposed surface, it can reach 50 years.
5. Fine flexibility at low temperaure, adaptable to cold conditions.
6. Root-resistance: The pvc membranes can be used on planting roofs.
7. Fine puncture resistance, joint peel srength and joint shear strength
8. Fine UV-resitance, no pollution to environment
9. Easily welding, installing, secure
10. Easy treaments to the delicate parts of corners and edges
11. Convenient maitance with low cost.
