Formaldehyde odor and irritation in POM processing

Fenómeno do problema
Strong formaldehyde pungent odor is produced during POM '2079851475616104452.
Análise das causas
POM thermally decomposes at high temperature >210°C, releasing formaldehyde gas, especially when the barrel temperature is too high or residence is too long.
Solução
Strictly control barrel temperature at 190-210°C not exceeding 230°C; shorten residence time; strong exhaust ventilation; use formaldehyde scavenger.
Conclusão principal
POM formaldehyde decomposition is the most prominent environmental and safety issue in processing.
