Severe equipment corrosion by PFA
Fenómeno del problema
The corrosive gas HF causes damage to equipment and molds
Análisis de la causa
PFA has trace decomposition of HF at the upper limit of the processing window
Solución
Adopt fluorine-corrosion-resistant Hastelloy/Monel alloys
Conclusión clave
The corrosiveness of PFA determines that equipment materials must have the highest level of fluorine resistance requirements
