TECHNOLOGY OVERVIEW

Basic Knowledge of Delrin

What is Delrin?

Delrin is a brand name for a type of acetal resin. It is a high-performance thermoplastic with excellent mechanical strength and stiffness. Acetal, discovered by Hermann Staudinger in 1920, was later commercially synthesized by DuPont in 1956. DuPont is the original manufacturer of Delrin. It's a type of plastic derived from hydrocarbon fuels through polymerization. Making Delrin involves generating anhydrous formaldehyde, polymerizing it, and stabilizing the resulting polymer.

Furthermore, it has low friction and exceptional dimensional stability, which is why it is often used in gears, bearings, and machinery components. It can be processed through methods like injection molding and extrusion due to its thermoplastic nature. With applications ranging from automotive parts to consumer goods, Delrin is valued for its resistance to wear, temperature stability, and versatility in manufacturing.

FAQ

Machining Delrin FAQs

Delrin is considered affordable compared to other materials in its category due to its versatile properties and ease of manufacturing.
Acetal is a generic name for a class of thermoplastics, and its chemical name is polyoxymethylene (POM). Delrin is a specific brand of Acetal, produced by DuPont.
Acetal and Delrin are both high-strength thermoplastics based on polyoxymethylene (POM). Acetal is the general name for polyoxymethylene, which is usually composed of two forms: copolymer and homopolymer. Delrin is a brand of Acetal homopolymer produced by DuPont, known for its higher purity, mechanical properties and consistency. Compared with copolymers, Delrin generally has better strength, stiffness, wear resistance and fatigue resistance, but may be slightly less stable than copolymers in certain chemical environments.
DEK can do delrin surface treatment including: As Machined Finish (excellent surface finish fresh) and Bead Blast
Delrin's common CNC machining processes include milling, turning and drilling. These processes can be used to produce a wide variety of shapes and complex components.
