SBS polymer modified bitumen waterproof membrane Torchable bitumen board takes SBS (styrene butadiene styrene) thermoplastic elastomer odified asphalt as dip coating material, takes high quality polyester (PY), fiberglass (G) ,fiberglass & polyethylene felt (PYG) as base materials,takes sand (S) ,mineral schist (M) ,polyethylene film (PE) ,etc as surface,which is produced by stirring and grinding with special equipment

APP bitumen waterproof membrane is made in the following way:base materials are firstly dipped into asphalt or thermoplastics(e.g. APP or APAO) and modified asphalt;then both surfaces are coated with elastomer or plastic asphalt; fine sands and mineral grains(pieces) or polyethylene membranes are spread or covered on its upper surface; fine sands or polyethylene membranes are spread or covered on its lower surface.

It has a good waterproof performance and aging-resistant capacity.It does not drip in high temperature,nor does break in low temperature.It is easy to use in construction,with no polluton to enviroment but a long service life.

Diffrence between SBS and APP membrane: 

SBS modified bitumen waterproof membrane is specially suitable to the buildings in cold area and to the buildings of changeable construction.

APP membrane is suitable to areas of high temperature and of strong sun-shine.
