PVC PVC waterproofing membrane
product description
A polyvinyl chloride (PVC) resin is added to a processing aid such as a plasticizer, an anti-UV agent, an anti-aging agent, a stabilizer, and the like, and a molded polymer waterproofing membrane is produced by an extrusion method. This product adopts a unique product formula, the product life is far beyond the general waterproof material, the entire waterproof system has a long service life, the roof is more than 30 years, the underground is more than 50 years, and it is widely used in construction and civil engineering.
Features
(1) High tensile strength, high elongation, and strong thermal dimensional stability.
(2) The low temperature flexibility is good, and the adaptability to the ambient temperature is good.
(3) Good puncture resistance and impact resistance, and excellent resistance to root puncture.
(4) Convenient construction, width over 2m, good integrity, less overlap, more economical, and high controllability of construction quality.
(5) Strong chemical resistance and suitable for special occasions.
Specification model
Mark | for class H (homogeneous), class L (fiber backing) and class P (fabric reinforcement)
