Polyvinyl chloride (PVC) – thermoplastic material
PVC stands for ‘polyvinyl chloride‘. The applications of this thermoplastic in the plastics industry are diverse. There are different types of PVC used in the wire and cable industry. National (VDE) and international (IEC) standardization authorities have specified PVC parameters for the various PVC compounds.
The properties of standardized PVC compounds for the cable industry are defined under the following VDE standards, for example:
PVC – insulation mixture EN 50363-3, VDE 0207-363-3
PVC – jacket mixture EN 503-163-4, VDE 0207-363-4-1
PVC that hardens after polymerization is not suitable for insulating and protecting wires and cables. The necessary mechanical, thermal and electrical levels can only be achieved with the addition of complements such as:
– filler material
– abrasive additives
