(1)Introduction of Commodity Plastomer(APP) modified asphalt waterproofing membrane is modified asphalt waterproofing membrane which adopt polyester felt or fiberglass felt as base, take random polypropylene (APP) or polyolefin polymer (APAO, APO) as modifier. And its double sides are covered by isolated materials .Its name is shortened as APP membrane. Implemented standard: Compulsory national standard GBl8243 2000 (2)Specification: Table 2 Variety of APP Membranes Base Surface material polyester felt glass fibre polyethylene film PYPE GPE fine sand PYS GS mineral grains PYM GM Code: PY polyester base, Gglassfiber base, PE polyethylene film, S fine sand, M mineral grain specification breadth,1000mm. thickness: PY fiber:3mm and 4mm; G fiber:2mm, 3mm and 4mm. area per roll: 15m2(2mm), 10m2(3mm) and 7.5m2(4mm) membrane can be divided into type I and type II according to physical mechanical property. Package: Plastic bag per roll (3)Application It is applicable for construction roof waterproof, underground moisture-resistant, water dam anti-seepage, pond and canal, and anti pollution and anti seepage of chemical and metallurgical engineering. It can be bonded directly with cement and other materials in the solidification process. The construction is simple, and under room temperature. Its useful life is 50 years or more. APP waterproof membrane is suitable for hot area to use.
