Background
During world war ii, navy once engaged in their largest shipbuilding projects, using thousands of kilometers of rubber-coated cable. However, due to the lack of supply of rubber, and the tendency to burn in the emergency, the fire spreads throughout the hull. The naval finally selected plasticized PVC as a flame retardant insulated cable for shipboard cables.
Polyvinyl chloride was used for the first time in household cables in 1939.
BFGoodrich corporation produced commercially in 1946 a polyvinyl chloride blend comprising PVC, a soft polymer/PVC and nitrile rubber blend.
