What is sbs, app modified asphalt waterproofing membrane
Compared to the use of SBS waterproofing membrane to use a larger range. But each has its own advantages and disadvantages, according to the local environment and the actual situation of the building in combination with the characteristics of two kinds of coil to choose materials. You have to compare the next, I can only tell you SBS waterproofing membrane prices than APP waterproofing membrane high.
Their characteristics and differences: First, SBS modified asphalt waterproofing membrane (polyester tires): SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven , Jute cloth, glass fiber mats were made for the fetal base, the plastic film for the anti-sticking isolation layer, the selection, ingredients, eutectic, invasion, composite molding, curling and other processes processing production. Such as building dragon TJ-242 SBS elastomer modified asphalt waterproofing membrane.
Features: The use of polyester felt (filament polyester non-woven) mechanical properties, water resistance, corrosion resistance is also very good; elastic and low temperature performance has improved significantly, the effective range of (-25 ~ 100) ℃; Excellent fatigue resistance.
Use: for high-level and high-rise buildings of the roof of the single-layer laying and composite use, can also be used for basement and other waterproof and moisture, more suitable for the northern cold areas and structural flexibility of the building waterproof.
Second, APP modified asphalt waterproofing membrane (polyester tires): polyester felt or glass fiber mat for the fetal base, random polypropylene (APP) or polyolefin polymer (APAO, APO) for modified asphalt Dip coating, covered with insulating material on both sides of the waterproofing membrane. Such as building dragon TJ-243 APP plastic modified asphalt waterproofing membrane.
Features: Good elasticity, heat resistance and resistance to UV aging; its softening point above 150 ℃; temperature range of use -15 ℃ ~ 130 ℃; good corrosion resistance, high self-ignition point (265 ℃); Low temperature performance slightly lower than the SBS waterproofing membrane; hot melt is very good, very suitable for hot melt construction.
Scope: Compared with the SBS waterproofing membrane, in addition to the general use of the project, APP modified asphalt waterproofing membrane because of better heat resistance and has excellent resistance to UV aging, more suitable for high temperature hot or ultraviolet radiation Area of ??building waterproof.
