Rubber grade. Kaolin is classified by particle size as hard or soft, with hard clays having a slightly smaller particle size which yields a stiffer uncured compound resulting in a higher tensile strength and abrasion resistance when cured. The pH required is 4.5-5 since fillers with an excessively acidic pH accelerate the curing.
