RC-90
(Active Alumina Silicate in Rubber)

.Product's application
RC-90(super fine active aluminum silicate), with the appearance of white powder,is mainly applied in rubber as an active filler with superior property. It has the properties of superfinely grinding, small distribution range, psrticular surface modification,easy dispersion,low screen residue retained, stable quality, good excess weld and abrasion resistance.It is applicable in nstural rubber, rubber polymer and colophony, Especially in rubber it represents excellent excess weld and abrasion rwsistance. It is applicable in natural rubber, rubber polymer and colophony, Especially in rubber it represents excellent excess weld and abrasion resistance. RC-90 has high tension at break, tear strength, extension modulus, excellent abrasion resistance and the similar excess weld capacity with currency carbon black and can replace it largely. Rubber composition including RC-90 has superior allround performance and the properties of thermostability acid and alkali proof, chemical solvent resistance. With the easy process, low power expenditure and low price, it can be filled largely without any effect on product's property,and it can help to greatly cut product's costs.
