Acetal is a semi-crystalline engineering plastic known for its high stiffness, low friction, and excellent dimensional stability. It maintains its shape and performance even when exposed to humidity and varying temperatures. Key Properties

Let’s break down exactly what acetals are, how they work, and why you should care about them. acetally

Acetal resin (Polyoxymethylene, Delrin®) is an engineering plastic. It's strong, stiff, and has low friction. You've used it if you've ever handled a zipper, a car door lock, or a gear in a power tool. The polymer backbone is a long chain of repeating acetals: (-O-CH₂-O-CH₂-)ₙ.
