Rubber additives calcined kaolin clay JYCK96

Rubber additives calcined kaolin for rubber with super whitness,very low residue,fine particle size,satisfying opacity

The JY-CK96 series of kaolin based pigments are produced through delamination,calcination and classification.The well-controled processes ensure the JY series has no coarse particles and maintains an absolute minimum of mesh residue,so the end user can acheive a high Hegman grind.The JY-CK95/96 series pigments also have  high brighthness, strong hiding power and superior dispersibility,and it is widely applied in rubber. Its main benefits are:             It's the best extender of titanium dioxide with excellent opacity that can improve efficiency  and cut costs by partly replacing titanium dioxide .             It offers superfine particle and with excellent anti-setting property.It is inert to most acids and alkaline at ambiente temperature and offers good anticorrosive capabilities.
