APP modified bitumen membrane

APP modified bitumen membrane

APP modified bitumen membrane is made by saturating the base in bitumen, or thermoplastics (such as APP,APAO,APO), then covering double faces with thermoplastic elastomer (SBS) and last finishing the upward face with fine sands, mineral slates(or grains) or polythene membrane etc. while downward face with fine sands or polythene membrane.

Characteristic:

 Good impermeability; Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack; SBS modified bitumen membrane is specially being applied in the cold area with low temperature, while APP modified bitumen membrane is applied in the hot area with high temperature; Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering; Construction is convenient, the melt method can operate in four seasons, joints are reliable

Specification:

Applicable scope:

Suitable for civil building roofing, underground, bridge, parking, pool, tunnel in the line of waterproofing and dampproof, especially for the building under high temperature. According the roofing engineering stipulation, APP modified bitumen membrane could be used in the Grade Ⅰ civil building and industrial building which has special waterproofing requirement.
