heat resistant plastic

A Guide to Heat Resistant Plastics: Types, Properties, and Selection

Plastic parts are often used in environments where temperature is not stable. Some are close to motors, some sit inside electrical enclosures, and some need to keep their shape during repeated heating. In these cases, ordinary plastics may soften, deform, or lose performance too early. That is why heat proof plastics are important. They are
