PETG deformation in high-temperature sterilization
Sorun Belirtisi
PETG products deform severely in high-temperature steam sterilization at 121°C or in hot water.
Neden Analizi
The PETG heat deflection temperature is about 70-80°C, far below the sterilization temperature, and the low crystallinity cannot withstand high temperature.
Çözüm
Switch to a heat-resistant copolyester such as Tritan; PETG is only suitable for low-temperature sterilization (ethylene oxide, etc.); mark the use temperature limit.
Temel Çıkarım
PETG is not suitable for high-temperature steam sterilization.
