New Material Designed to Meet Global Needs
Thanks to our unique technology to control the shape and composition of titanates, Otsuka Chemical has developed a new series of compound materials. These titanates are primarily used in automotive brake pads as friction modifiers. We continue to expand usage globally as well as design cutting edge new grades offering improved friction characteristics.

Advantages
TERRACESS, used as a friction modifier, can improve μ stability, wear resistance, fade property, and NVH.
These benefits are based on physical or mechanical properties caused by the titanates chemical structure and shape, and chemical reactions occurring at the friction interface caused by the chemical properties of the titanates.
By controlling these different properties we have created many grades with various characteristics. So we can always supply a suitable filler for our customer.
