Flexible or plasticizer PVC has been used to produce cable and wire insulation and sheathing for more than 50 years. The performance specification for PVC formulations employed for wire and cable coating or jacketing depends upon the nature of the wire and cable and the use to which it is to be put. Typically, wire and cables in automobiles are required to withstand temperatures as high as 150°C due to the heat generated by the passage of electricity through the cable and as low as -40°C to ensure the insulation is preserved if the automobile is subject to extreme weather conditions. Low temperature performance is also required for cables such as outdoor extension cables that are used in cold climates.
Here are two examples:
Softener formulation adjustment can raise the continuous operating
temperature limit to 105°C.
Aluminium trihydroxide (ATH) additive can systematically reduce
flammability and smoke formation. Regulatory authorities such as
the VDE, EN or UL issue standardized property profiles for
insulation and coating compounds.
