Delrin is a remarkably strong and durable plastic originally formulated as a cheaper alternative to metal castings. First introduced by the DuPont chemical company in 1960, Delrin acetal homopolymer, also known as polyoxymethylene (POM) or acetal, is a synthetic polymer and thermoplastic known for its rigidity and resistance to wear. In industrial or mechanical applications, Delrin components serve as reliable and less expensive alternatives to metal parts. Delrin has a low coefficient of friction and high-wear resistance which make it perfect for high-contact components like gears, rollers, or bearings. Furthermore, Delrin components have high resistance to warping or shifting over time regardless of their environment. And due to its natural water and moisture resistance, it is often used in applications subject to wetness (pumps or valves for example). And with its natural resistance to most chemicals and abrasive solvents, Delrin components are known to last much longer than comparable parts built of other plastics.
Delrin is an excellent thermoplastic for injection molding applications and Delrin machining and Delrin fabricating can be accomplished with relative ease compared to other hard plastics. In contrast to other hard plastics, however, bonding Delrin is rather difficult under normal circumstances. However advances in Delrin fabrication techniques have made bonding fairly commonplace for Delrin fabricators. As far as Delrin distribution and sales, it is available for purchase in rods and sheets of varying thicknesses. A crystalline plastic, Delrin is white in its original state, though other colors are available as well. For more on Delrin fabrication applications, contact the experts at JC Finley.
