SAB Kabel

General Information Polyvinylchloride (PVC)

Polyvinylchloride (PVC) - thermoplastic material

The application areas for this thermoplast in the plastics industry are diverse. There are various types of PVC used in the wire and cable industry. National (DIN VDE) and International (IEC) Standards Authorities have specified PVC parameters for the different PVC mixtures. The characteristics of standardized PVC mixtures for the cable industry are defined under the following DIN VDE standards, for example:

  • PVC - insulation mixture VDE 0207 part 363-3, EN 50363-3
  • PVC - sheath mixture VDE 0207 part 363-4, EN 50363-4

PVC that hardens after polymerisation is not suitable for insulating and protecting wires and cables. The necessary mechanical, thermal, and electrical levels can only be reached with the addition of complements such as:

  • softeners
  • stabilisers
  • filler materials
  • slip additives

 

 

Materials

1. SAB-special PVC (Y)

Our special PVC (YA and YM) are used for insulation and sheathing purposes. PVC type YA is used for core insulation and is particularly flexible and has very good electrical characteristics. PVC type YM sheath material has good mechanical characteristics and high flexibility. The temperature range is as follows:

fixed laying:-40°C bis +70°C
flexible application:+ 5°C bis +70°C

 

2. SAB-cold resistant PVC (YK)

Cold resistant PVC shows good flexibility and mechanical strength even at sub-zero temperatures. It can also be exposed to various weather influences. The temperature range is as follows:

fixed laying:-40°C bis +70°C
flexible application:-20°C bis +70 °C

 

3. SAB-heat resistant PVC (YW)

Heat resistant PVC can resist temperatures up to +105°C. The insulation and sheath materials possess good electrical and mechanical values and have very good heat resistance. The highest valid operational temperature on the conductor itself according to DIN VDE 0207 is +90 °C. Any application above this temperature reduces the usable life. The temperature range is as follows:

fixed laying:-40°C bis +90°C
flexible application:+ 5°C bis +90 °C
short time use:bis+105 °C
 

 

4. SAB-oil resistant PVC (YOE)

Our YOE PVC mixtures are oil resistant according to DIN VDE 0281 part 1, mixture TM5. Usually used as a sheath material, it can also be used as insulation. The temperature range is as follows:

fixed laying:-40°C bis +70°C
flexible application:+ 5°C bis +70 °C

 

PVC can be classified as inflammable due to its chemical composition. SAB PVC compounds fulfil the criteria regarding burning characteristics according to EN 60332-1-2 (IEC 60332-1-2), UL, VW1, CSA FT1 and FT2. Halogen is however re­leased during a fire, which is a danger to humans, nature, buildings and machines. In addition, PVC control and data cables are not designed for outdoor use.
