Ultra-Machinable Acetal Rods

Made of naturally slippery acetal copolymer, these rods and discs are an economical alternative to Delrin® acetal resin. They offer similar wear resistance and are equally resistant to expanding when exposed to heat and moisture. They can be machined to close tolerances and are often used to make precision gears, bushing, bearings, and rollers.

Ultra-Low-Friction Acetal Rods

A silicone additive gives these rods a self-lubricating surface that reduces friction and extends the life of your parts.

Red—Red is also known as Turcite X; it is more slippery than blue, making it suitable for low-load applications at high speeds.

Antistatic Acetal Rods

When static is a concern, machine your conveyor components, rollers, and other moving parts from these antistatic acetal copolymer rods. These rods have a naturally slippery, wear-resistant surface. They resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. They’re also excellent electrical insulators.
