Delrin Acetal Copolymer Rod - Black 30mm Diameter x 300mm Long, Grade A
Black Delrin Acetal Copolymer Rod – 30mm x 300mm | Grade A
This Grade A Black Delrin Acetal Copolymer Rod is one of the most versatile engineering plastics available. Renowned for its excellent load-bearing qualities, low moisture absorption, and outstanding machinability, it delivers consistent performance across mechanical, electrical, automotive, and industrial applications. Black Delrin offers the same high-performance properties as natural white, with added UV stability from the carbon black pigment.
Key Benefits
- High tensile strength and stiffness – outperforms many polymers on impact resistance, enabling thinner and lighter part design
- Low coefficient of friction – ideal for sliding, wear, and bearing applications
- Excellent creep resistance – maintains dimensional stability under sustained load
- Low water absorption – resistant to a wide range of solvents and chemicals
- Good electrical and dielectric properties – suitable for insulators and electronic components
- Easy to machine – produces a clean, precise finish; ideal for spur gears and precision parts
- UV stable – carbon black pigment provides improved resistance to UV degradation vs natural grade
- Wide service temperature range – -29°C to 85°C continuous (intermittent to 93.3°C)
