| Abstract: | Core material thickness of polyethylene polypropylene composite waterproofing sheet plays important roles on production cost, waterproofing properties and service life. This article studies the influences of core material thickness on room temperature tensile properties, tear strength, alkaline resistance, hot air aging properties and artificial weathering properties. The results show that the increasing of core material thickness will improve the above properties. |
