RAW MATERIALS RANGE GUIDE
Glass bubbles are low density hollow glass microspheres that have a high strength-to-density ratio, decreasing density and increasing buoyancy of a material making it a cost effective and water resistant additive for many different applications. Glass bubbles can be used in oil drilling fluid to increase drill lubricity and reduce wear.
Glycols are used as lubricants in water-based muds, also having the added benefit of increasing shale stability. Bisley supplies Polyethylene Glycol and others upon request.
Graphite has a low coefficient of friction and is used as a torque reducer in water-based drilling muds. Bisley supplies amorphous, natural and synthetic graphite.
