Acetal Round Bar - White 80mm Diameter x 100mm - Grade A POM-C

Grade A white Acetal copolymer (POM-C) round bar, 80mm diameter cut to 100mm long. Acetal is one of the most versatile engineering plastics — combining high stiffness, low friction, and excellent dimensional stability in a material that machines to a superb finish. Ideal for precision components where tight tolerances are required.

Key Properties

• High tensile strength and stiffness
• Low coefficient of friction — self-lubricating
• Excellent dimensional stability and creep resistance
• Good chemical resistance to solvents, fuels, and oils
• Low moisture absorption (<0.2%) — stable in wet environments
• Service temperature: -29°C to 85°C continuous, 93°C intermittent
• Easy to machine, drill, turn, and mill to tight tolerances
