Acetal Rod (POM C) | Natural | Cut to Size | Delrin Copolymer Round Bar | Food Safe

Premium Natural Acetal Copolymer (POM C) round bar, cut to length. Natural is the most widely specified grade for food contact, pharmaceutical, and precision engineering applications. Naturally self-lubricating with exceptional dimensional stability, high strength, and excellent machinability. FDA and EU 10/2011 food compliant. A reliable metal replacement for demanding mechanical applications.

Note: Supplied without protective film.

Product Highlights

• Material: Acetal Copolymer (POM C) -- also known as Delrin, Polyoxymethylene
• Colour: Natural (off-white / ivory)
• Form: Solid Round Bar / Rod
• Surface Finish: Smooth
• Temperature Range: -50°C to +100°C (long term continuous use)
• Food Compliance: FDA approved and EU 10/2011 compliant. Suitable for direct food contact applications.
• Length Tolerance: +/-3mm — if tighter tolerances are required, please contact us before ordering

Properties

• Self-Lubricating: Naturally low coefficient of friction with excellent sliding and wear resistance. Ideal for moving parts without the need for additional lubrication.
• High Strength & Stiffness: Tensile strength of 66 MPa and tensile modulus of 3,000 MPa. Capable of withstanding significant mechanical loads -- a true metal replacement.
• Excellent Machinability: One of the easiest engineering plastics to machine. Produces clean chips, holds tight tolerances, and does not gum up cutting tools.
• High Dimensional Stability: Moisture absorption of just 0.80% at saturation. Parts hold their shape and tolerances even in wet or humid conditions.
• Chemical Resistance: Resistant to solvents, oils, fuels, and alkalis (pH 4-13). Superior to Acetal H (Homopolymer / Delrin) in chemical and hot water environments.
• Impact Resistant: Unnotched impact strength shows no break under test conditions. Maintains toughness down to -50°C.
• Low Risk of Centreline Porosity: Copolymer structure eliminates the voids and bubbles found in homopolymer grades -- critical for high-precision machining and turning.

Applications

• Food Processing & Pharmaceutical: FDA and EU compliant. Industry standard for food processing machinery, pharmaceutical equipment, and hygienic environments where colour traceability is required.
• Precision Turned Components: Shafts, spacers, plugs, bushings, and custom turned parts. Machines and turns to a fine surface finish with tight tolerances.
• Bearings & Wear Parts: Self-lubricating properties make it ideal for plain bearings, wear guides, slides, and conveyor components.
• Gears & Cams: High stiffness and dimensional stability make it ideal for gears, cams, ratchets, and locking mechanisms.
• Automotive & Fuel Systems: Excellent resistance to fuels, oils, and solvents. Used for valve bodies, pump parts, and fuel system components.
• Electrical & Electronic: Good electrical insulation. Used for insulating spacers, housings, and connector components.
• General Engineering: A cost-effective metal replacement across a wide range of structural and mechanical applications.
