SEBS Thermoplastic elastomer
热塑性橡胶SEBS产品耐老化性能优良，广泛用于高弹性制品、包履材料（工具手柄）、聚合物改性、胶粘剂与密封剂、医疗器械、电线电缆的填充料等。
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具有较好的耐温性能，其脆化温度≤－60℃，最高时使用温度达到149℃，在氧气气氛下其分解温度大于270℃。SEBS有优异的耐老化性能，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有优良的电性能，其介电损耗在一千赫为1.3×10，一兆赫为2.3×10；体积电阻是一分钟9×10Ω-cm,二分钟2×10Ω-cm。SEBS具有良好的溶解性能和共混性能，其溶解度参数在7.2-7.6之间。
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.

● SEBS通过与聚丙烯、环烷油或氢化环烷油、白油等混合可生产邵A0-95度的弹性体，此类弹性体有优异的表面质感和耐候抗老化性能，可广泛用于软接触材料如手柄、文具、玩具、运动器材的握手、密封条、电线电缆、牙刷柄及其它包覆材料等。
● SEBS通过化学改性或共混于增韧尼龙（PA6）、聚碳酸脂（PC）聚苯醚（PPO）聚脂（PET、PBT）、聚丙烯（PP）作塑料共混的相容剂等。
● SEBS可用作工程塑料的相容剂，如作PE与PS相容剂。
● SEBS与聚丙烯、白油阻燃剂等共混可用于生产电线电缆的护套或外表皮。
● SEBS通过与碳五等石油树脂配合可用于生产高档粘胶剂、密封剂。
● SEBS具有耐老化性能，可直接用于润滑油粘度指数稳定剂。
