The temperature of commonly used soda-calcium glass is 270~250℃, and the can can be sterilized at 85~105℃. Medical glass, such as safety parts and salt bottles, should be sterilized at 121℃ and 0.12mpa for 30min.
As for the use of high borosilicate glass and glass-ceramics higher temperature, heat resistant cooking utensils and tableware, thermal shock resistance in 120℃ above, low fire cooking utensils for the rapid cooling and heat resistance in 150℃ above, open fire glass cooking utensils for the rapid cooling and heat resistance can reach more than 400℃.
The use of plastic temperature is relatively narrow, neither low temperature, not to withstand slightly higher temperature, such as polyvinyl chloride (PVC) use temperature of a 20~60℃, thermosetting polyester (PET) for a 30~110℃, polyethylene (PE) for -40~100℃, polypropylene (PP) for a 40~120℃; General plastic lunch box should not be heated in microwave oven, even if the quality of good polypropylene lunch box, heating temperature in 120℃ above that plasticizer precipitation.
