The heat resistance of different materials varies depending on their chemical composition and structure. The following are the heat resistance properties of some common materials:
- Metal: Metal usually has good heat resistance, depending on the type of metal and alloy composition. For example, aluminum alloys usually have high thermal conductivity and heat resistance and are suitable for high temperature environments.
- Plastic: ABS: ABS plastic begins to soften at about 70-80 degrees Celsius, so it may be deformed in high temperature environments. PLA: PLA filament at lower temperatures, about 50-60 degrees Celsius, so it is not suitable for high temperature environments. PETG: PETG has a high heat resistance, can maintain structural stability at higher temperatures, usually can withstand 70-80 degrees Celsius temperature. PC: PC is an engineering plastic that has high heat resistance and can maintain structural integrity at higher temperatures, and common PC plastics can withstand temperatures above 90 degrees Celsius.
- Acrylic: Acrylic usually has good heat resistance and can withstand relatively high temperatures, but may soften or deform at extremely high temperatures.
- Wood: The heat resistance of wood is usually poor, easy to heat deformation and carbonization, so it is not suitable for high temperature environment.
I think that when selecting materials, it is necessary to consider their heat resistance according to the actual application environment and requirements. If you need to use in a high temperature environment, you should choose a material with good heat resistance, such as metal or specific engineering plastics. If it is only used in a general room temperature environment, common ABS, PLA and other plastics can also meet most needs.
