Waterproofing Membrane

Waterproofing SAM930 self-adhesive polymer modified bituminous membrane with polyester reinforcement CE Certificated China well known trade mark "Yuhong" Brand It consists of high strength polyester as reinforcement and polymeric modified bitumen which is self-adhere at normal temperatures. On its upper surface is such isolation material as polyethylene film, fine sand or aluminum foil and on the lower surface is peelable silicon-coated isolation film or buckle paper as anti-sticking isolation material. Specification: (1) According to the physical properties, it can be classified into type I and type . (2) According to the upper surface material, it can be classified into polyethylene film(PE) type, fine sand type(S), and aluminum foil(AL) type. Dimension; Area: 10m215m2 Width:1000mm thickness: 2mm 3mm. Physical Property: The product meets the industry standard JC 8982002 Self-adhesive polyester modified bituminous sheet material using polyester reinforcement for waterproofing.
