Self-adhesive polymer modified bitumious waterproofing membrane using polymer modified bitumen adhesive material as main material(internal could have reinforcement),double or single coated with silicone oil isolating membrane or isolating paper as antiseize
II. Product Categories:
Reinforcement: no reinforcement (N) polyester (PY)
Top surface of N type: polyethylene (PE), polyester (PET), double sides adhesive without film (D).
Top surface of PY type: polyethylene (PE), sand(S), double sides adhesive without film (D).
Performance of Material: I & II. Thickness of 2.0mm of PY only have I type.
III. Product features:
The construction of the membrane is concise and environmental: without firing, remove the isolation can adhesive at the basic tightly, it's environmental and economic.
2. Good elongation and elasticity, so it could adapt to deformation and cracking of basic well.
3. The membranes adhesive performance with basic is excellent, can avoid running water.
4. The self-healing is strong. the adhesive layer can heal automatically to protect waterproof layer in the case of puncturing.
IV. Applicable scope:The waterproof membrane is suitable for industrial and civil roofing, basement, indoor, municipal engineering, reservoirs, swimming pool, subway, road and tunnel. It also used in wood and metal roofing especially suitable for oil depot, chemical factory, textile mill, granary etc.
