Ostar 60S
Product description
Ostar 60S is a kind of highly active kaolin powder material treated by special process, and its chemical composition is anhydrous Aluminium silicate.Applied to wires and cables,It helps to improve the volume resistivity,reduce the parameters of the medium,absorb the acid and maintain good moisture resistance,as to extend the working life of them.Ostar 60S has moderate fineness, high activity, and can also be applied in the cement industry, significantly improving the early and late strength of ordinary cement and special cement.
