Application
1. ZC-120P is a versatile inorganic chemical which are used for
reinforcement of rubber seals, battery separators, rubber sacs,
belts and tyres industries etc.
2. ZC-120P possesses a high reinforcing potential and imparts to
rubber compounds as the lower specific surface.it can improve high
shore hardness, tensile strength, tear resistance and abrasion
resistance, less deformation under compression, extended products
life.
3. In order to achieve optimum rubber technical data the addition
of activators like glycols, amines or other alkaline accelerators
is necessary.
