熱塑性橡膠SEBS

　　SEBS Thermoplastic elastomer

　　熱塑性橡膠SEBS產品耐老化性能優良，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℃，最高時使用溫度達到149℃，在氧氣氣氛下其分解溫度大于270℃。SEBS有優異的耐老化性能，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.

　　主要牌號有:YH-501、YH-502、YH-503、YH-561、YH-602

　　注:*20%甲苯溶液 ^10%甲苯溶液

　　< SEBS通過與聚丙烯、環烷油或氫化環烷油、白油等混合可生產邵A0-95度的彈性體，此類彈性體有優異的表面質感和耐候抗老化性能，可廣泛用于軟接觸材料如手柄、文具、玩具、運動器材的握手、密封條、電線電纜、牙刷柄及其它包覆材料等。

　　< SEBS通過化學改性或共混于增韌尼龍（PA6）、聚碳酸脂（PC）聚苯醚（PPO）聚脂（PET、PBT）、聚丙烯（PP）作塑料共混的相容劑等。

　　< SEBS可用作工程塑料的相容劑，如作PE與PS相容劑。

　　< SEBS與聚丙烯、白油阻燃劑等共混可用于生產電線電纜的護套或外表皮。

　　< SEBS通過與碳五等石油樹脂配合可用于生產高檔粘膠劑、密封劑。

　　< SEBS具有耐老化性能，可直接用于潤滑油粘度指數穩定劑。
