Acetal (Delrin & Celcon) Balls

Profile

Acetal balls offer predictable mechanical, chemical and electrical properties over a broad temperature range for extended periods of time. They exhibit good fatigue resistance, impact resistance, tensile and shear strength and dimensional stability. They have very low moisture absorption characteristics. Delrin balls maintain a natural lubricity, giving them a low coefficient of friction against metals.

Most resins used for these balls meet FDA, USDA and UL requirements. Other names include polyoxymethylene (POM) and polyacetal.

Delrin is a DuPont product: Celcon is a Hoechst Celanese product.
