Kraton(美國科騰)SEBS KRATON G1651 HUKRATON? G1651 H苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物Kraton Polymers LLC產(chǎn)品說明：Kraton G1651 H is a clear, linear copolymer based on styrene and ethylene/butylene with a polystyrene content of 33%. It is supplied from North America in the physical form identified below.Kraton G1651 HU - supplied as an undusted powderKraton G1651 HS - supplied as a dusted powderKraton G1651 H is used as a base material for themoplastic elastomer (TPE) compound formulations for a variety of applications. It is also used as a modifier of thermoplastics and bitumen. The inherent stability of SEBS polymers suggests the use of G1651 H in applications that must withstand weathering and high processing temperatures.KRATON G1651 H 物性表基本信息添加劑抗氧化性特性共聚物抗氧化性耐氣候影響性能良好耐熱性，高用途復(fù)合塑料改性外觀清晰/透明形式粉狀加工方法壓縮模塑物理性能額定值單位制測(cè)試方法比重0.910g/cm3ASTM D4025Antioxidant Additive 10.030 到 0.10%內(nèi)部方法Polystyrene Content31 到 35%內(nèi)部方法Total Extractables%內(nèi)部方法揮發(fā)物%內(nèi)部方法熔體流動(dòng) - 230°C/5kgNo FlowASTM D1238補(bǔ)充信息額定值Styrene/Rubber ratio33/67硬度額定值單位制測(cè)試方法肖氏硬度 (邵氏 A, 10 秒, 模壓成型)60ASTM D2240彈性體額定值單位制測(cè)試方法抗張強(qiáng)度 (屈服)> 27.6MPa內(nèi)部方法伸長率 (斷裂)> 800%內(nèi)部方法
