Material Notes:
GAR-DUR® plastic parts are made from ultra high molecular weight (UHMW) polymer having a molecular weight of 4.2 million and greater. Garland Manufacturing Company has been processing UHMW resin for over 45 years. This true UHMW polymer is excellent for resisting abrasion and corrosion while contributing a low coefficient of friction. Fabricated Gar-Dur® parts have helped companies improve performance, reduce downtime, eliminate the need for lubrication, replace steel parts and lower their operating costs.Applications: GAR-DUR® machined parts are being used in mining, pulp and paper operations, refrigeration, chemical plants, material handling industries, and automotive assembly plants to name just a few.Advantages: GAR-DUR® is designed to function in corrosive and chemical environments, in extreme cold and where abrasion resistance is a desirable factor. It is durable, has a very low coefficient of friction and high impact resistance, it is much quieter than metals, and it won't absorb fluids.Information provided by Garland Manufacturing.
