Self-adhesive Polymer Modified Polyester Fiber Membrane

Brief Introduction
1. Self-adhesive polymer modified polyester fiber membrane is a kind of self-adhesive waterproof material
2. Embryo substrate: polyester fiber non-woven cloth
3. Dipping material: polymeric modified bitumen
4. Upper surface isolating material: polyethylene film, fine sand or aluminum foil
5. Anti-sticking isolating material: peelable silicon-coated isolating film or buckle paper

Features
1. No toxicity
2. No pollution
3. Environmentally-friendly waterproof material
4. High adhesive strength

Applications:
1. Non-exposed roofing projects
2. Waterproofing for such engineering projects as subway, tunnel, pool and aqueduct
