Self-adhesive Polymer Modified Bitumen Waterproofing Membrane Suitable For Flat Roofs And Sloped Roofs
Product Appearance
Felt Surface Condition: The base material shall be fully impregnated, no unimpregnated areas. The surface shall be flat, and no holes, edge defects, cracks or lumps are allowed. When unrolling the coil any product temperature between 4℃ and 50℃, there shall be no cracks or adhesions exceeding 10mm in outside the 1000mm length from the core. No more than one such defect is allowed. No than one joint is allowed, and the length of the shorter section shall not be less than 1000mm. The joint be cut neatly and extended by 150mm.
Physical Performance
Self-adhesive polymer modified bitumen waterproofing membrane uses self-adhesive polymer modified bitumen as the base material, adopts fiberless carrier (for non-exposed) or polyester carrier as reinforcement, takes polyethylene film, polyester film, fine sand surface materials or no film (double-sided self-adhesive), and is a self-adhesive waterproofing sheet with-adhesive release layer.

Product Features
This waterproof roll has rubber elasticity and excellent elongation, which adapt well to the deformation and cracking of the base layer; it does not require adhesives or heating to melt, just tear off the isolation layer and it can bond to the base layer. The construction is convenient and the construction speed is fast This roll has excellent adhesion to the base layer, and the adhesion is often greater than its force (fracture outside the bonding surface); it has self-healing property, that is, when the roll encounters puncture or embedding of hard objects it will automatically heal together with these objects, so it can still maintain good waterproof performance. This roll has excellent durability, acid resistance, alkali resistance and chemical resistance (except for the surface part of aluminum foil rolls), and has excellent aging resistance in various environments.
