Elastomer (SBS) Modified Bituminous Waterproof Sheet Material

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.
