道桥用改性沥青防水卷材

产品简介Product introduction

道桥用改性沥青防水卷材，是以热塑性弹性体SBS或聚烯烃聚合物APP(APAO)改性材料为主，辅以各种助剂制成的改性沥青浸涂聚酯胎基，上表面撒以细砂、矿物粒（片）料或覆以聚乙烯膜，下表面覆以细砂、聚乙烯膜而制成的道桥专用优质防水卷材。

It takes TPE SBS or APP (APAO) modified material as main material and adds various additives to produce modified asphalt. Then dip-coat it over polyester base, spray fine sand or mineral dust (piece) over the upper surface or cover the upper surface by polyethylene film, and spray fine sand over the bottom surface and cover it by polyethylene film. It is excellent waterproof roll material dedicated for roads and bridges.
