GB-KR90(Superfine active aluminum silicate) is formed by particular thermal treatment and surface preparation. Its appearance is white super fine powder and particle size is as fine as sub-micron. Its pH value is 6.0-7.0 and it can be applied in natural rubber, rubber polymer and colophony as white active filler.
The rubber with GB-KR90 has high colorability, opacity and extrudability. The product has the same excellent excess weld property and abrasion resistance as carbon white.
The rubber has advantages of good allround performance, electrical property and other properties of thermostability, acid and alkali resistance and chemical solvent resistance, and is a superior filler of tint rubber product as a substitution of carbon white. It's applied in various tint rubber products.
