HY-X-55
Product Description
HY-X-55 is a dry produced 1250 mesh calcined kaolin powder material. The chemical composition is anhydrous aluminum silicate. Pure texture, low impurity content, kaolin content >98% are their basic properties. Low heavy metal, stable color and suitably application make it popular in medical butyl rubber packaging materials. It has a good reinforcing performance for butyl rubber products with fine particle size, narrow distribution and low 325 mesh sieve residue. It can improve the stability and corrosion resistance of medical butyl adhesive materials due easy to disperse, good processing performance, strong chemical stability and almost no reaction with any chemical reagents or drugs at room temperature. It is also used in paint industry.
