3. SBS Modified Asphalt Waterproof sheet
Definition
SBS modified asphalt waterproof sheet is a kind of waterproof sheet material formed by dipping support with SBS modified asphalt. It is sprayed plastic asphalt on both sides, with sewing fine sand, mineral particles or covering polyethylene film on the upper side and at the bottom.
It belongs to elastomer sheet (thermoplastic plastomer).
Both fiberglass and polyester texture can be used as the support.

17. APP modified asphalt waterproof sheet
Application
It is widely used on all kinds of water proofing and damp proofing projects, especially in areas at high temperature or in strong solar radiation.
Tab 35 and its belowings can be used in multi-layer water proofing
Tabs above tab 35 can be used in unique-layer water proofing and multi-layer water proofing as well as in heat construction
Besides the two kinds of materials, polymer modified asphalt waterproof sheet material also contains other kinds of polymer and supports with different properties and ranges in water proofing.
