Specifications
SBS modified asphalt membrane
Flexibility at low temperature
High tensile strength and elongation
Easy to applicate
SBS modified bitumen roll waterproofing membrane
Feature
1) High Impermeability ,high tensile strength, high extension coefficient good dimensional stability, adopting shocking well to substratum contraction deformation and crack.
2)puncture resistance,tear resistance, corrosion resistance, mildew resistance, good weather ability.
3Good property of resistance high and low temperature. SBS is suitable for the lower temperature environment but APP for the higher temperature environment.
4)Perfect durability, long life span up to 30 years.
5)Either heating and melting method or cold adhesive method, either single or multiple layer.
6Neither dripping in high temperature nor breaking in low temperature, no pollution to environment and convenient installation.
