Sabit Plastoflex is the ultimate Waterproofing Membrane. The multilayered design consists of 250gr/m2 non-woven polyester core, impregnated and coated on both sides with APP (Atactic Polypropylene Polymer) modified bitumen, and finally finshied with heat fusible polyethylene film on both surfaces. Sabit Plastoflex modified bituminous waterproofing membrane are produced from a blend of special grade thermoplastic polymers and bitumen….. This combination gives the proven waterproofing qualities of bitumen plasticity, excellent resistance to heat, ageing & weathering, and ease of application by torch welding. the polyester core gives the membrane high tensile strength, elongation and superior lap joint strength.
