SBS是三嵌段聚合物,常温下呈强韧的高弹性体,高温下呈接近线聚合物的流体状态。其主要物理性能如下:①抗拉断裂强度>2.94MPa;②直角撕裂强度>9.8kN/m;③断裂伸长度>30%;④耐热度;80℃/45°角/5小时不流淌;⑤低温柔度:-20℃无裂纹;⑥不透水性:0.098MPa/1800秒合格;⑦紫外老化: 50℃±2℃(1000瓦)200小时不龟裂。SBS改性沥青柔性油毡,具有纸胎油毡不可比拟的优点。高温不流淌,低温不脆裂,耐疲劳、抗老化、韧性强、弹性好,防水性能优异,施工简便,环境适应性广,冬季亦可施工,有效防水年限可达15年以上。适用于屋面、墙体、厕浴间、地下室、冷
SBS is a triblock polymer that exhibits a strong, high elasticity at room temperature and a fluid state near the polymer at high temperatures. Its main physical properties are as follows: 1 tensile strength at break> 2.94 MPa; 2 right-angle tear strength> 9.8 kN/m; 3 elongation at break> 30%; 4 heat resistance; 80°C/45° angle for 5 hours without flowing ;5 Low temperature flexibility: -20°C without cracks; 6 Water impermeability: 0.098MPa/1800 seconds qualified; 7UV aging: 50°C±2°C (1000W) 200 hours without cracking. SBS modified bitumen flexible linoleum has advantages that are unmatched by the paper tire felt. High temperature does not flow, low temperature is not brittle, fatigue resistance, anti-aging, toughness, good elasticity, excellent waterproof performance, easy construction, wide environmental adaptability, winter can also be construction, effective waterproof period of up to 15 years. Suitable for roofs, walls, toilets, basements, cold
