A cetal resins (polyoxymethylene or POM) are engineering thermoplastics based on formaldehyde polymerization technology. A cetal resins have high tensile strength, stiffness, resilience, fatigue endurance, a low coefficient of friction against metals, a cetals and other plastics and moderate toughness. The A cetal sheet has high resistance to organic solvents, excellent dimensional stability, a low coefficient of friction and outstanding abrasion resistance among thermoplastics.
A cetals' resistance to creep is excellent. Moisture, lubricants and solvents have little effect on this property, which is important in parts incorporating self-threading screws or interference fits. Good electrical properties qualify these materials for electrical applications requiring long-term stability. A cetal copolymers retain much of their toughness through a broad temperature range and are among the most creepresistant of the crystalline thermoplastics. A low moisture absorption characteristic permits molded parts to serve reliably in environments involving humidity variations.
