- Regulatory compliance needs
- Cost considerations
POM Q & A
Q: What's the difference between POM and nylon?
A: POM offers better dimensional stability and creep resistance, while nylon has higher impact strength.
Q: Can POM be used for food contact applications?
A: Yes, certain FDA-approved grades are suitable for food processing equipment.
Q: What temperature range can POM withstand?
A: Typically -40°C to 100°C (-40°F to 212°F) for continuous use.
Q: Is POM recyclable?
A: Yes, POM can be recycled, though specialized processes are required.
Q: How does moisture affect POM?
A: POM absorbs minimal moisture (0.2-0.3%), but drying before processing is recommended.
