1. Polyacetal, also commonly known as acetal or polyoxymethylene (POM), is a formaldehyde-based, semi-crystalline engineering thermoplastic which contains the functional group of a carbon bonded to two -OR groups.
2. It is 100% recyclable. POM is known as polyformaldehyde, polymethylene glycol and polyoxymethylene glycol.
3. Polyoxymethyene resins demonstrate well-balanced properties ranging for mechanical to physical and flammability performance.
4. The key benefits of POM resins include:
· Excellent mechanical properties over a temperature range upto 140°C, down to -40°C
o High tensile strength, rigidity and toughness (short-term)
o Low tendency to creep (as compared to nylon) and fatigue (long-term). Not susceptible to environmental stress cracking
· High degree of crystallinity and excellent dimensional stability
· Excellent wear resistance
· Low coefficient of friction
· Good resistance to organic solvents and chemicals (except phenols) at room temperature
· Low smoke emission
· High gloss surfaces
· Low moisture absorption
