The average fibre length is 2.5 microns, which is within a size category determined by medical research studies as being devoid of pathogenic potential. It is a bluish-while powder with a specific gravity of 1.8 and a dry bulk density of 30G500 ml/ 100 g. The material has an electropositive charge and is capable of absorbing 3290 of its weight in oil. The mineral components impart 2 important properties; the lap shear strength of prismatic laths, and fibre reinforcement. The ore consists of 85% lizardite and 15% chrysotile.It has a number of uses, particularly as filler for plastics and paper. In the plastics industry, it is used in phenolic and polyester molding compounds and gelcoats as reinforcing filler. It can also be used in vinyl flooring, vinyl acetate, epoxy adhesives, acrylic, melamine, mylar, polypropylene and polyethylene. It is an extender of cellulose fibres in paperboard, construction, and cover paper. It can be used in newsprint and other printing papers for improvements in print quality and opacity. The pulp and paper industry utilize the absorption property of the product or pitch control. Other general uses include refractory compounds for steel production, welding rod flux coatings, texture and rust Proof Paints, stains and primer paints, friction materials, asphalt paving, sealants, grease, and wood preservatives.
