CAS號:40372-72-3

別名:si-69、硅69、雙[Y-(三乙氧基硅)丙基]-四硫化物、4,4',15,15-四乙氧基-3,16-二氧雜-8,9,10,11-四硫雜-4,15-二硅雜十八烷、雙[-(三乙氧基硅)丙基]-四硫化物、3,3’ -四硫雙(丙基三乙氧基硅烷)

分子式:(C2H5O)3Si(CH2)3-S4-(CH2)3Si(OC2H5)3

EINECS號:254-896-5

用途:si-69是一種已經在橡膠工業中得以成功應用的多功能團有機硅橡膠、輪胎助劑。其作用在于提高橡膠的彈性模量和抗拉強度,顯著改善橡膠的耐磨性能和壓縮性能,同時降低橡膠粘度,節約加工耗能。JH-S69最適用于在含雙鍵聚合物或其共混物中采用含羥基填料的橡膠配方。適用的填料包括白炭煙、硅酸鹽、白堊等;適用的橡膠包括天然橡膠(NR)、丁苯橡膠(SBR)、異戊二烯橡膠(IR)、丁二烯橡膠(BR)、丁腈橡膠(NBR)和三元乙丙橡膠(EPDM)等。

包裝:5L、10L、25L、200L PE塑料桶或1000L IBC桶包裝。
