Established in 1904, Elkem is one of the world’s leading companies in the environmentally responsible manufacture of metals and materials. Elkem is a fully-integrated producer with operations throughout the silicon value chain from quartz to silicon and downstream silicone specialities as well as speciality ferrosilicon alloys and carbon materials. Elkem consists of four business areas: Silicones, Silicon Materials, Foundry Products and Carbon.
After being acquired by Orkla in 2005, selling off the aluminium and power businesses, and being acquired by China National Bluestar in 2011, Elkem has now returned its main focus to the business areas that started with the invention of the Söderberg electrode in 1917.
With the sustainable and innovative production of silicones, silicon for renewable energy, silicon-based alloys and carbon products, we are looking to strengthen our position in key markets as well as to expand in new parts of the world.

Sidistar®可改善橡胶加工过程中的流变性。
The addition of SIDISTAR® to conveyor belt compounds will not only significantly improve the mixing and processing but also the properties of the final product, especially the dynamic behaviour; Goodrich heat build-up will be reduced and fatigue life (de Mattia test) extended by up to 40% (number of cycles for formation of a crack of a certain length).
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. 一种提高传动带疲劳强度的橡胶助剂埃肯R300。Betachem埃肯降低生热协效剂

埃肯特种白炭黑介绍
产品介绍:
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。
• 沉淀法二样化硅: 细小颗粒的团聚体,无法分散成单个颗粒
• Sidistar: 可以分散成初级(单个)球形颗粒
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
• 无需使用硅烷偶联剂
• 其他 丙烯酸酯橡胶埃肯碱性白炭黑
