(Polyoxymethylene)
Acetal polymers are semi-crystalline. They offer excellent inherent lubricity, fatigue resistance, and chemical resistance.
Acetals suffer from outgassing problems at elevated temperatures, and are brittle at low temperatures. Glass filled, and added lubrication grades are available, flame retardant grades are not.
| Max Temp. | Chemical Resistance | Tensile Strength | Flexural Modulus | Impact Strength |
| 180°-300° F | Excellent | 6,000-22,000 psi | 120,000-170,000 psi | .8-2 ft-lb/in notched izod |
Pros
High tensile strength with rigidity and toughness
Good impact and solvent resistance
Glossy molded surface
Low static and dynamic coefficients of friction (slippery)
Many grades have FDA and NSF approvals on food and water contact
Replace die-cast metal components
Cons
Difficult to bond
Poor resistance to acid and bases
Subject to UV degradation
