PVC is often used for electrical cable jacketing due to its excellent electrical insulating properties and dielectric constant. PVC is commonly used in low voltage cable (up to 10 KV), telecommunication lines, and electrical wiring.
Basic formulation for the production of PVC insulation and jacket compounds for wire and cable is generally composed of the following:
PVC
Plasticizer
Filler
Pigment
Stabilizers and co-stabilizers
Lubricants
Additives (flame retardants, UV-absorbers, etc.)
Below is an example of a very basic starting point for a PVC wire coating formulation:
Formulation PHR
PVC 100
ESO 5
Ca/Zn or Ba/Zn Stabilizer 5
Plasticizers (DOP, DINP, DIDP) 20 – 50
Calcium Carbonate 40- 75
Titanium Dioxide 3
Antimony Trioxide 3
Antioxidant 1
