SBS modified pitch waterproofing sheet

SBS modified pitch waterproofing sheet A. Introduction SBS elastomer modified pitch waterproofing sheet uses polyester cloth or glass fiber as its substrate ,adopting the SBS modified additives,surfacing with materials such as PE membrane,fine sand,colour sand,shale piece. We utilize the most advanced production equipment and technique which can disperse the SBS high polymer to the enforcem net structure. Thereby the waterproofing sheet has excellent performances, such as tensile strength,good ductility,resistance to high and low temperature,anti-ozone-aging ,resistance to temperature deviation. The whole performances exceeds the requirements of GB18242. The durability of the product is more than 20 years. Besides SBS elastomer modified pitch waterproofing sheet,we also produce pitch compound fetous pitch waterproofing and its whole performance can meet the demand of JC/T690. B.
