SEBS Thermoplastic elastomer
熱塑性橡膠SEBS產(chǎn)品耐老化性能優(yōu)良,廣泛用于高彈性制品、包履材料(工具手柄)、聚合物改性、膠粘劑與密封劑、醫(yī)療器械、電線電纜的填充料等。
SEBS is of excellent aging resistance and used for highly elastic products, packing material (tool handles) polymer modification,adhesives,sealant,meddical treatment equipment and fillers of wires and cables.
SEBS具有較好的耐溫性能,其脆化溫度≤-60℃,*時(shí)使用溫度達(dá)到149℃,在氧氣氣氛下其分解溫度大于270℃。SEBS有優(yōu)異的耐老化性能,在人工加速老化箱中老化一星期其性能的下降率小于10%。SEBS有優(yōu)良的電性能,其介電損耗在一千赫為1.3×10,一兆赫為2.3×10;體積電阻是一分鐘9×10Ω-cm,二分鐘2×10Ω-cm。SEBS具有良好的溶解性能和共混性能,其溶解度參數(shù)在7.2-7.6之間。
SEBS is of good temperature endurance with brittle temperature lower than-60℃and highest service temperature at149℃,Under oxygen surround. The decomposing point is higher than270℃.SEBS has excellent aging resistance and the drop rate of its performance is less than 10% after being aged in the artificial aging accelerator for one week.
SEBS is also very good at electrical property Its dielectric loss is 1.3×10 at 1KHZ and 2.3×10 at 1MHZ; its volume resistance is 9×10Ω-cm one minute and 2×10Ω-cm two minutes. SEBS has good solubility and co-mixing capacity with solubility between 7.2~7.6.
