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)

Technical Specifications

Tensile strength at yield: ~65 MPa
Elongation at break: ~25%
Flexural modulus: ~2,600 MPa
Impact strength (Izod notched): ~75 J/m
Hardness (Rockwell M): ~80
Service temperature (continuous): -29°C to 85°C
Service temperature (intermittent): up to 93.3°C
Water absorption (24hr): <0.25%
Coefficient of friction (vs steel): ~0.2
Colour: Black (carbon black pigment)
