SBS Modified Bitumen Membranes

SBS modified bitumen membrane

SBS-modified bitumen membrane is made by saturating the base in bitumen, or thermoplastic elastomer (such as styrene butadiene-SBS), reinforcing with polyester or fiberglass, finishing the upward face with fine sands, mineral slates (or grains) or polythene membrane, etc.

 

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 mainly applied in a cold area with low temperature, while APP-modified bitumen membrane is applied in a 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.

Applicable scope:

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

 

Storage and transportation instructions

When storage and transportation, Different types and sizes of products shall be stacked separately, and should not be mixed. Storage temperature should not be above 50℃, the height is not more than two layers, and in the course of transportation, the membrane must stand.

The stacking height is not more than two layers. To prevent the tilt or pressure, when necessary cover the felt fabric.

In normal conditions of storage and transportation, the storage period is a year from the date of production.
