Delrin (Nylon) Custom CNC Machining Canada

Delrin, also known as acetal or polyoxymethylene (POM), is a high-performance thermoplastic polymer known for its exceptional strength, stiffness, and dimensional stability. Manufactured through a polymerization process that converts formaldehyde into polymer chains, Delrin is produced in the form of pellets, which are then processed into various shapes using methods like injection molding, extrusion, or machining. Delrin is commonly used in applications requiring high strength and low friction, such as in gears, bearings, bushings, automotive components, and electrical insulators. Its low coefficient of friction and high wear resistance make it ideal for precision parts in demanding industries like automotive, aerospace, and industrial machinery.

The advantages of Delrin include its excellent mechanical properties, such as high tensile strength, stiffness, and resistance to fatigue, making it suitable for load-bearing applications. It also offers outstanding chemical resistance, particularly to fuels, solvents, and lubricants, and has a low friction coefficient, which minimizes wear and extends the lifespan of components. Additionally, Delrin is highly resistant to moisture absorption, maintaining its strength and dimensional stability even in humid conditions. However, Delrin also has some disadvantages: it can be difficult to weld and is not as impact-resistant as some other plastics like polycarbonate. Additionally, while it performs well in many environments, it can degrade under exposure to high temperatures and certain chemicals. Despite these drawbacks, Delrin remains a popular choice in industries where high performance, durability, and precision are essential.
