—Filament polyester filler base sheet material:
·The combination of filament polyester filler base and SBS modified bitumen forms an excellent comprehensive performance and high quality waterproof sheet material;
·High strength waterproof layer and strong water pressure resistance;
·Good performance of breaking resistance, tearing resistance, fatigue resistance, corrosion resistance, mould resistance and weather resistance;
·High tensile strength, high elongation, high adaptive capacity to base shrinkage deformation and fracture;
·Good resistance performance of low and high temperature: It could still work under -20℃ , be applicable to cold and hot regions, especially in chilly region;
·Good workability: It can be constructed by heat fusion method in the four seasons of the whole year and hot-joint is reliable and durable.
—Alkali-free glass fiber filler base sheet material:
·Combination of economical filler base and high performance SBS modified bitumen.
·Higher tensile strength, excellent resistance to high and low temperature.
·Good performance of corrosion resistance, mould resistance, weather resistance and good workability.
—Glass fiber reinforced polyester filler base sheet material:
·It is safe and eco-friendly by using mechanical mounting of construction.
·The product has better dimensional stabiliy.
