Buy Acetal Online: Explore the Different Acetal Grades

thyssenkrupp Engineered Plastics offers Acetal plastic, a thermoplastic made from POM (polyoxymethylene) resin. Known for its excellent dimensional stability and ease of machining to close tolerances, Acetal exhibits unique properties such as minimal moisture absorption, high tensile strength, and low creep. These physical characteristics remain consistent across various environments and temperatures up to 180ºF. Alongside its exceptional abrasion resistance, Acetal plastic stands as one of the most widely utilized engineered plastics available. It is often preferred for replacing parts traditionally machined from metals.

Features and Benefits of Acetal

• Excellent for general purpose parts in wet environments
• Machines well to tight tolerances
• Homopolymer and Copolymer versions available to fit different applications
• Filled versions available
• Available in FDA and USDA compliant grades

thyssenkrupp Engineered Plastics offers two primary versions of Acetal: homopolymer and copolymer. Chemically, these materials are approximately 90% identical; however, each variety offers its own unique benefits.

Acetal Homopolymer

• Rigid
• Thermoforms easily
• Can be used in a wide variety of applications
• Impact resistant
• Good chemical resistant
• Low moisture absorption
• Stiffer than acetal copolymers with higher flexural modulus at ambient temperature and in elevated temperature applications
• Higher impact strengths at both ambient temperature and low temperatures
• Roughly 10-15% higher tensile strength and copolymers 
• Higher continuous use temperature than copolymers (203°F vs. 194°F)
