PROCESSING
Because PFA is corrosive in the melt, machinery used to process Hyflon should be lined with corrosion resistant alloys.

HEALTH SAFETY AND ENVIRONMENT
Hyflon® PFA 120X is a very inert polymer and it is not harmful if used and handled according to standard processing procedures.
If handled inappropriately, it may release harmful toxic chemicals. Please refer to the Material Safety Data Sheets for more information on handling and safety.

PACKAGING AND STORAGE
Hyflon® PFA 120X resin is available in 25 kg (55 lbs) and 600 kg (1323 lbs) packaging. Though it has an indefinite shelf life, it is recommended to store it in a clean area, protected from direct sunlight, and possible contamination.
