elastomer (sbs) modified bituminous waterproof sheet material -九游会真人

product introduction:

hls-110 elastomer(sbs) modified bitumen waterproof membrane is saturating the membrane base with modified bitumen, thermoplastic elastomer (styrene butadiene-sbs), reinforced with polyester or fiberglass, with fine sand, mineral slate(or grains)or polythene membrane on top.

execution standard:nation standard gb 18242-2008 “styrene butadiene styrene (sbs) modified bituminous sheet material”
  • advantages
  • performance

1.high strength waterproof layer and strong water pressure resistance;
2.high tensile strength, high elongation, high adaptive capacity to base shrinkage deformation and fracture;
3.good resistance performance of low and high temperature: it could still work under -20℃, be applicable to cold and hot regions, especially in chilly region;
4.good performance of breaking resistance, tearing resistance, fatigue resistance, corrosion resistance, mould resistance and weather resistance;
5.good workability: it can be constructed by heat fusion method in the four seasons of the whole year and hot-joint is reliable and durable.
