Title: Manufacture of foaming vinyl sheath wire/cable
Inventor: MIZUNO KOICHI
IPC: B29K105/04
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To increase the bubble fraction of a sheath layer and provide excellent insulation performance with a satisfactory state of insulation-resistance foaming cells, by applying to a sheath an ethylene-vinyl acetate copolymer mixed with azodicarbonamide as foaming agent. SOLUTION: Azodicarbonamide as foaming agent is mixed, as master batch having an ethylene-vinyl acetate copolymer as base resin, into a vinyl chloride resin composition. One to 50% of the master batch is suitable as the mixing rate of the azodicarbonamide. The mixing rate of the azodicarboxylic acid amide relative to the soft vinyl chloride resin composition can be adjusted according to the bubble fraction of a sheath and suitably is 0.001 to 0.5%. Because the azodicarboxylic acid amide is used as the master batch mixed into the ethylene-vinyl acetate copolymer, foaming efficiency is improved and the amount of the azodicarboxylic acid amide used can be limited to a small value. Electrical adverse effects of a decomposition product of the azodicarboxylic acid amide on an insulator can be reduced.
