PVC Architectural Roof Membrane

PVC architectural roof membrane is a single-ply roofing material composed of polyvinyl chloride resin combined with plasticizers, stabilizers, and UV inhibitors. This formulation produces a flexible sheet with controlled thickness (1.2 mm to 2.0 mm) and width (up to 2.05 m). The membrane is manufactured via calendering or extrusion processes, resulting in a homogeneous structure with welded seams that form a continuous waterproofing layer. The material exhibits tensile strength ranging from 10 MPa to 15 MPa and elongation at break between 200% and 300%, accommodating structural movement and thermal expansion. Surface treatments include anti-aging coatings and embossed finishes to reduce glare and improve slip resistance.
