Delrin Machined Parts
A Guide to Delrin - CNC Milled & Turned Parts: Properties, Applications and Design Considerations
What is Delrin®?
Delrin is a brand name for an Acetal homopolymer made solely by DuPont™. Together with Acetal copolymers, Delrin is an engineering plastic known for being amongst the strongest and stiffest of all thermoplastics.
Main Attributes of Delrin®:
- Dimensional stability before, during and after machining
- Low moisture absorption
- Good chemical resistance to fuels and solvents
- Low friction and high wear resistance
- Wide operating temperature range (-40°C to 120°C)
- Good compressive strength
- Good shock resistance
- Easy to machine
Delrin in comparison to Acetal Copolymers:
- Higher flexural modulus at room temperature
- Higher impact strengths at room temperatures and low temperatures
- Tensile strength is approximately 10-15% higher than comparable copolymers
- Slightly higher continuous use temperature than copolymer (95°C vs. 90°C)
- Lower thermal expansion rate
- Better wear resistance
