PTFE Overheating Degradation
Sorun Belirtisi
PTFE shows yellowing, carbonization, or smoke release, chemical resistance and mechanical integrity decrease, a safety hazard.
Neden Analizi
Sintering temperature exceeding 380℃ causes thermal degradation; local hot spots in ovens, molds, or heaters; prolonged exposure above the recommended temperature upper limit; above 380℃ releases toxic fluoride gases.
Çözüm
①Precisely monitor sintering temperature not to exceed 380℃; ②Avoid prolonged exposure to the temperature upper limit; ③Use calibrated thermocouples and uniform heating equipment; ④Ventilation protection for high-temperature operations.
Temel Çıkarım
PTFE's 380℃ is a double red line of performance and safety; local hot spots are more dangerous than average temperature; toxic gas protection is an occupational health requirement.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
