Non Exposure Homogenous PVC Membrane
Service life of 20 years for exposed use;
High puncture and rooting resistance, especially suitable for planting roof system;
Introduction of Non Exposure Homogenous PVC Membrane
It is a new polymer waterproof membrane which is made from polyvinyl chloride resin, and mixed with plasticizer, filler, antioxygen, ultraviolet absorber and other auxiliaries. Hongyuan adopts automatic mixing of raw material, double-screw extruder and delicate three-roller calender equipment in the PVC membrane production. berry PVC waterproof membrane features dimensional stability and high tensile strength, being a best choice for many civil and industrial projects.Berry PVC waterproof membrane mainly falls into two categories: Homogeneous & Reinforced, each with different thickness specifications. Reinforced PVC waterproof membrane employs a fabric reinforced layer in the middle, it enhances the breaking and tear strength.
Features of Non Exposure Homogenous PVC Membrane
- Excellent performance in aging resistance, service life of 20 years for exposed use, and 50 years for non-exposed application
- High puncture and rooting resistance, especially suitable for planting roof system
- Easy installation and hot-air welding seam, environment friendly
- High tensile strength and elongation, size stability
- Good plasticity, convenient for detailing and coners installation
- Inherently fire resistant
- Smooth surface, unfading and stain resistance
