3、ymer of vinyl chloride andvinyl acetate.1.2 This insulation is recommended for use in power andcontrol circuits at temperatures not higher than 75C. At athickness of 15 mils (0.38 mm), application is limited tovoltage ratings below 300 V, and to dry locations. At athickness of 30 mils, the applicati
