How to Maximize the Property Advantages of Delrin® Acetal Homopolymer Over Acetal Copolymer: A Guide for Design Engineers
DuPont™ Delrin® acetal homopolymer resin - also called Delrin® POM-H - is one of the most crystalline engineering thermoplastics available. Delrin® is a highly adaptable material that bridges the gap between plastics and metals and offers unique properties. It is specified for high load mechanical applications and precision parts, where strength, stiffness, stability and reliability are important. Applications range from gears, safety restraint components, door system and conveyor systems components to medical delivery devices, ski bindings, zip fasteners and many other applications across a wide range of products and industries.
When compared to acetal copolymers, Delrin® homopolymer combines higher fatigue and creep resistance with overall higher toughness and higher tensile strength and stiffness, allowing for thinner and lighter part design, and the potential for reduced part production cost.
This white paper describes the differences between Delrin® homopolymer and acetal copolymer in detail and explains how to make the best use of the higher level of mechanical performance of Delrin® homopolymer over that of acetal copolymer in order to extract the most value for all stakeholders.
