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。
In succession to the development of industrial production technologies of SBS and SIS above 10000 tons, the Synthetic Rubber Division of Baling developed successfully the production technology of thermoplastic rubber SEBS owning the intellectual property. 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℃,最高時使用溫度達(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 at 149℃,Under oxygen surround. The decomposing point is higher than 270℃.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.
