Data Sheet Scotch 2242 Linerless Electrical Rubber Tape Heat Resistance Passes Product Description Applications ASTM D4388 Scotch 2242 Electrical Tape is an Primary insulation for cable splices economical, general purpose, rubber and terminations UV Resistance Passes tape. The tape is a highly ASTM D4388 conformable, linerless EPR (Ethylene Moisturesealing and insulating Propylene Rubber) based electrical electrical connections Flame Resistance Passes insulating tape. The tape is designed IEEE Std 271974 ANSI for use in splicing and terminating Bus bar insulation C37.20C 74 wires and cables rated up to 90C. The tape will meet industry Moisturesealing of cable ends Electrical Properties specifications for flame retardance and has the necessary physical and Motor leads Dielectric Strength electrical properties to provide ASTM D4325 750 V/mil immediate moisture seals and Wire and cable jacket repair Original (29.5 KV/mm) voidfree buildup.
