Avoid inhalation of these fumes. Ovens and process equipment should be vented and adequate ventilation provided in the working area. For further information refer to the Lineplus PTFE material safety data sheet. STORAGE AND STABILITY
TENFIL TF400 is stable for one year if stored in original unopened container at temperatures between +4°C - +35°C
(39,2°F – 95°F).
