High Transparency, Shorter Production Times, and Lower Energy Costs

New SIPERNAT® grades for the silicone rubber industry: clear advantages and expansion of Evonik’s product line. 

SIPERNAT® specialty silica is made by Evonik Industries, an industrial group based in Essen, Germany. This product line includes precipitated silica, aluminum silicates, and calcium silicates, which are added as reinforcing filler to various silicone rubber products.

The product line has now been enlarged to include two new specialty silica: SIPERNAT® 288 and SIPERNAT® 268. They were specially developed for customers who manufacture highly transparent end products (e.g., keyboards for mobile telephones, computers, remote controls, etc.). Reduced yellowing and outstanding mechanical properties distinguish SIPERNAT® 288 and SIPERNAT® 268. Both products can be processed quickly and dispersed easily, which reduces production times and lowers energy costs. These new SIPERNAT® products are intended for use in high-temperature vulcanized silicone rubber, liquid silicone rubber, and two-component room-temperature vulcanized silicone rubber.

SIPERNAT® 288 and SIPERNAT® 268 are manufactured by Evonik Wellink Silica (EWS) in Nanping, China. For further information, visit
