What is the difference between thermosetting and thermoplastic cable?
The terms are used to categorise cable insulation according to its properties, such as its operating temperature, rather than the ingredients from which it is are made.These terms are now used by the IEE Wiring Regulations to describe insulation formerly described, for example, as 'pvc' (a 'thermoplastic' material) or rubber ( a 'thermosetting' material).

What is the purpose of rubber or plastic insulation around appliance cords?
Rubber tends to not burn as easily as plastic. Also, rubber is more moisture-resistant than plastic. If rubber burns, the fumes from burning rubber are safer than fumes from burning plastic. Sometimes rubber is used because the cord tends to remain more flexible with rubber insulation.
