Pvc waterproofing sheet is Polyvinyl chloride (PVC) waterproofing membrane,that is based on polyvinyl chloride resin as raw material, mixed with plasticizers, fillers, antioxidants, UV absorbers and other additives such as a squeeze Into a new type of polymer waterproofing membrane.
It has a green environmental protection, non-toxic, harmless, non-polluting, with long-term plasticity, recyclable size and color, stable long-term weather resistance, anti-ultraviolet and heat aging resistance, excellent low temperature flexibility, from the fire Self-extinguishing, effective resistance to harmful chemical substances, industrial pollutants erosion, wear resistance, seams formed by hot air welding, solid and reliable, with long-term solderability, construction convenience, according to the base surface, duration selection of different construction technology , Good plasticity, suitable for detailed treatment, easy maintenance and low cost, width of 2 meters, less material construction loss, smooth surface, easy to stick ash, easy to clean, conducive to the spread of water vapor (closed moisture can be discharged through the coil Will lead to blisters), anti-ultraviolet and anti-solar radiation, to meet the green building LEED certification requirements, can be directly exposed to use, without protective layer, up to 25 years or more reasonable life.
1, PVC waterproofing membrane tensile strength, elongation, thermal size change rate is small.
2, with good weldability, seam hot air welding and base metal into one.
3, with good water vapor diffusion, condensate easy to release, leaving the grass-roots moisture, moisture easy to discharge.
4, anti-aging, resistant to ultraviolet radiation, chemical resistance, resistance to root penetration.
5, low temperature (-20 ℃) has a good flexibility.
6, long life (roof 25 years, more than 50 years underground), and no environmental pollution.
7, the color of the surface reflection of ultraviolet radiation, PVC waterproof membrane surface absorption of less heat, low temperature.
8, excellent flexibility and stretch, high tensile strength, excellent dimensional stability, high mechanical strength, corrosion resistance, resistance to root system permeability, weatherability and anti-ultraviolet, anti-hail.
9, can be recycled, the waste material can add new materials and small materials to repeat the production and utilization.
