Product Description

Elastomer (SBS) Modified Bituminous Waterproof Membrane

Elastomer (SBS) Modified Bituminous Waterproof Sheet Material is a thermoplastic and elastic

modified bituminous dipping and coatingmaterial made out of Stylene-Butadiene-Stylene (SBS),the filler base is polyester felt, glass fiber felt and glass fiber reinforced polyester felt, it is a kind of rollable sheet water proof materials with the surface cover of the isolating materials like polyethylene film, fine sand and mineral slice (or particle) etc.

Advantages

1. Spunbonded polyester fiber membrane integrated advantage properties of spunbonded polyester substrates and SBS modified asphalt, wonderful integrated properties.
2. It could form waterproof layer, which has high strength and good property to stand against water pressure;
3. High tensile strength and elongation rate, strong adaptability for substrate shrinking distortion and cracks;
4. Good high and low temperature resistance, could keep its functions at -50degree and be used in cold or hot areas, especially in cold areas;
5. Resistance to puncture, pressing and rubbing, tearing, and wearing;.
6. Good resistance to corrosion, mildew and weathering;
7. Good construction performance, with firm and enduring joints;.

Properties
"Yuhong" brand waterproof membrane of elastomer (SBS) modified asphalt is a kind of windable sheet waterproof material, which adopts styrene-butadiene-styrene (SBS) modified asphalt as a dipping and covering modifier, whose upper surface is coated by PE film, fine sand, mineral granules or aluminum foil, copper foils or other isolating materials.
