Sidistar与沉淀法白炭黑的区别—加工性能
沉淀法二氧化硅
• 难分散,粘度提高明显,混入速度慢,加工性能极差
• 需要用硅烷偶联剂进行表面处理
Sidistar
• 易分散,混入速度快,降低门尼粘度,极易加工
• 无需使用硅烷偶联 埃肯R300可以提高各种橡胶的抗疲劳效果、降低生烟、提高动态性能、改善硬度、拉伸/撕裂强度等硫化胶性能。纤维用埃肯抗疲劳剂
Sidistar R300&R320&R320U是采用独特工艺生产的二氧化硅无机材料,外观呈灰色或灰白色,无定型球状结构,平均粒子大小在150Nm,由于这种结构Sidistar呈现了与普通白炭黑截然不同的用途:Sidistar可被分散为初级形态的亚微米级球形结构在体系中通过其特有的滚珠效应从而有效减少内摩擦,改善胶料流动性和填料分散性能,同时可以维持甚至改善硬度、拉伸/撕裂强度等硫化胶性能。当 SIDISTAR 用量增加, 能够有效提高硫化制品耐疲劳性能。
耐疲劳剂:
用途: 降低生热, ***提高产品耐疲劳和屈挠性能
推荐应用: 减震制品, 传动带, 胶囊, 轮胎带束层,胎侧,胎面
用法 : 3-8 phr, 因 SIDISTAR 补强性能不强, 需要与炭黑或普通白炭黑并用, 以取得良好的物性. 混炼初期加入
• R300 是以初级粒子形式分散的
• 滚珠效应***降低填料之间的内摩擦 , 减少生热 , 大幅度提高疲劳寿命 效果好的埃肯碱性白炭黑它在磁性、催化性、光吸收、热阻和熔点等方面与常规材料相比显示出特异功能,因而得到人们的极大重视。

The flame retardancy of the material will be increased when SIDISTAR® is used in combination with fillers like aluminium trihydrate or magnesium hydroxide. The amount of plasticizer can be reduced to further improve the fire behaviour. Thermal ageing and oil resistance are not negatively affected. SIDISTAR® acts by its physical properties particle size and spherical particle shape, it reduces internal friction and improves filler dispersion. It can be used in many different polymers and in combination with all kinds of fillers and plasticizers. 纤维用埃肯抗疲劳剂
