But brother, this heat-resistant temperature has a lot to do with various materials and additives, but in reality our materials are mostly mixtures. In addition, you are dealing with different membrane and plate profiles.
General crystalline resins, such as PE, PP, PA, etc. You can keep their shape below the melting point, but you can't guarantee their performance, depending on how high your requirements are, but they can be used for a long time below the glass transition temperature. Amorphous resins such as PVC and PS are used at higher temperatures.
The heat resistance of the resin is approximately
PE (up to 80 degrees), PP (about 70℃, up to 120℃), polystyrene (about 60-80 PS after long-term use), PVC plasticizer can reach 120 degrees, and ordinary PVC soles are estimated to be 80 degrees.
PA is an engineering plastic with high temperature, which can reach 100℃ after long-term use, generally above or around 150℃.
PMMA (organic glass) 60-80℃,
ABS-40℃ to 100℃
PC -60~ 120℃
Melamine MF is used at high temperature, but the exact number is not very certain, and it may decompose at 300 degrees.
