Comparison of two bitumen waterproof membranes

As a common material for waterproofing construction of daily buildings, both membranes are suitable for the following areas:

Waterproofing and moisture-proofing of roofs, walls, basements, toilets of key waterproofing projects and industrial and civil buildings; waterproofing of bridges, roads, parking lots, swimming pools, tunnels, cisterns ; Protection of pipelines and anticorrosive layers.

However, the two types of asphalt waterproofing membranes also have obvious differences in the scope of application, the main difference is that they are adapted to different ambient temperatures. SBS waterproofing membrane is particularly suitable for buildings in cold areas, and APP waterproof membrane is especially suitable for waterproofing buildings in higher temperature environments.

The reason why the two have the above-mentioned differences is that the two have different wetting materials.

SBS modified asphalt waterproof membrane is made of SBS thermoplastic elastomer modified asphalt as dip coating material, high-quality polyester felt, glass fiber felt, glass fiber reinforced polyester felt as the base, fine sand, mineral pellets, PE film, aluminum film, etc. are covering materials, and the elastomer-modified asphalt waterproof membrane is made by special mechanical stirring and grinding.

APP modified asphalt waterproof membrane is made of APP or APAO, APO modified asphalt as dip coating material, high-quality polyester felt, glass fiber felt as tire base, and fine sand, mineral pellets, and PE film as covering materials Plastic body modified asphalt waterproofing membrane refined by advanced technology.
