Acetal Sheet Description
Acetal, also known as polyoxymethylene (POM), is a high-strength, low-friction engineering plastic with excellent wear properties in both wet and dry environments. Acetal is chemically resistant to hydrocarbons, solvents, and neutral chemicals. Easy to machine, acetal makes an outstanding choice for applications that require complex, tight tolerances.
Acetal resins are engineering thermoplastics based on formaldehyde polymerization technology. Acetal resins offer high tensile strength, stiffness, resilience, fatigue endurance, and a low coefficient of friction against metals, acetals, and other plastics. Its superior creep resistance makes acetal a good choice when dimensional stability is needed.
Overview
Acetal copolymers retain much of their toughness through a broad temperature range and are among the most creep resistant of the crystalline thermoplastics. A low moisture absorption characteristic permits molded parts to serve reliably in environments involving humidity variations. Acetal sheets outperform other materials like nylon in high-moisture environments or when submerged. These sheets have a naturally slippery surface and are commonly used to create precision parts like gears, bearings, and bushings.
