Reef: charts A & B PVC Compounds Characteristics As Insulating & sheathing Material.
These charts summarize, Some of pertinent characteristics of PVC insulating and Sheathing compounds in order to help on ensuring the correct use of the material from a variety of compound which are now being specified in the international standards and to guide the users to select an appropriate cable design where in most suitable materials combinations has been used to meet specific environmental and installation conditions to guarantee trouble free services through out intended service life of product. However these chats are neither complete in listing all PVC compounds nor in providing all the related properties for very specific application and while anticipating all possible hazards, one has to contact the manufacturer.

1. Above indicated performance characteristics are dependent on, other properties & colour of compound.
2. Resistance to chemical and solvent are only for guidance, it is advisable in specific case to consult the manufacturer.
3. 105 oC in certain conditions.
4. Resistance to general purpose mineral oils, but are mot intended for continuous immersion in oil.
