The main difference in material properties between SBS modified asphalt waterproofing membrane and APP modified asphalt waterproofing membrane is that SBS modified asphalt waterproofing membrane has better low-temperature performance (low-temperature flexibility) and is suitable for use in cold regions; The APP modified asphalt waterproofing membrane has good high temperature performance (heat resistance) and is suitable for use in hot areas. The price difference between the two types of rolls is not significant.

Most of the modifiers for self-adhesive polymer modified asphalt waterproofing membranes are SBS elastomers, which have lower high-temperature performance (heat resistance) and mechanical properties than SBS modified asphalt waterproofing membranes. However, the advantage of this type of membrane is that it ensures the adhesion between the membrane and the base layer, providing both waterproof and sealing functions.
