Application
ZC - 165P possesses a high reinforcing potential and imparts to
rubber compounds particularly high shore hardness, tensile
strength, tear resistance and abrasion resistance.
In order to achieve optimum rubber-technical data the addition of
activators like glycols, amines or other alkaline accelerators is
necessary.
