Features
1. Spunbonded polyester fiber membrane integrated advantage properties of spunbonded polyester substrates and SBS modified asphalt, wonderful integrated properties.
2. It could form waterproof layer, which has high strength and good property to stand against water pressure
3. High tensile strength and elongation rate, strong adaptability for substrate shrinking distortion and cracks
4. Good high and low temperature resistance, could keep its functions at -50 and be used in cold or hot areas, especially in cold areas;
5. Resistance to puncture, pressing and rubbing, tearing, and wearing
6. Good resistance to corrosion, mildew and weathering
7. Good construction performance, with firm and enduring joints.
8. No alkali glass fiber membranepretty high tensile strength, wonderful high and low temperature resistance, resistance to damnification, corrosion, mildew and weathering; good construction performance.
Application Range
It could be widely used in all kinds of waterproof engineering projects in all fields, especially in the following types of engineering projects:
1. All kinds of building roofs engineering projects, exposed, non-exposed, heat preservation, non-heat preservation, planting building roofs and roof parking lots;
2. All kinds of underground waterproof or dampproof engineering projects;
3. Bridge surfaces of subways, tunnels, concrete roads, sewage treatment and garbage burying projects
4. water spraying pools, swimming pools, penstocks, water pools, and so on.
