GP - PVC Polyvinyl Chloride (PVC) Waterproof Membrane

Polyvinyl Chloride (PVC) waterproofing membrane is a high-quality, polymer waterproof sheet material. It is a polymer waterproofing membrane produced by the extrusion method, in which plasticizers, anti-ultraviolet agents, anti-aging agents, stabilizers and other processing aids are added to the PVC resin.

The internally - reinforced and stiffened Polyvinyl Chloride (PVC) waterproofing membrane is a thermoplastic PVC membrane. This membrane uses polyester fiber fabric or glass fiber as the reinforcing rib. Through a special extrusion - coating process, the polyvinyl chloride plastic layers on both sides and the polyester or glass - fiber reinforcing rib in the middle are combined into one to form a high - molecular - weight membrane.

Product Classification

●H (Homogeneous Membrane): Polyvinyl chloride waterproof membrane without internal reinforcement material or backing material.

●L (Fiber - backed Membrane): Polyvinyl chloride waterproof membrane with a fabric such as polyester non - woven fabric laminated on the lower surface of the membrane.

●P (Fabric - reinforced Membrane): Polyvinyl chloride waterproof membrane with polyester or glass - fiber mesh fabric used for reinforcement in the middle of the membrane.
●G (Glass - fiber - reinforced Membrane): Polyvinyl chloride waterproof membrane in which chopped glass fibers or glass - fiber non - woven fabrics are added. It has no obvious effect on the mechanical properties such as tensile properties, but only improves the dimensional stability of the product.

●GL (Glass - fiber - reinforced and Fiber - backed Membrane): Polyvinyl chloride waterproof membrane in which chopped glass fibers or glass - fiber non - woven fabrics are added, and a fabric such as polyester non - woven fabric is laminated on the lower surface of the membrane.

Product Characteristic

●High tensile strength and small dimensional change rate after heat treatment.

●Convenient for construction, and the welding is firm and reliable.

●Strong resistance to chemical corrosion, suitable for special occasions.

●It has good plasticity, making it convenient and quick to handle the details at corners and edges.

Implementation Standard
