Scotch 2242 Linerless Electrical Rubber Tape Product Description Scotch 2242 Electrical Tape is an economical, general purpose, rubber tape. The tape is a highly conformable, linerless EPR (Ethylene Propylene Rubber) based electrical insulating tape. The tape is designed for use in splicing and terminating wires and cables rated up to 90°C. The tape will meet industry specifications for flame retardance and has the necessary physical and electrical properties to provide immediate moisture seals and void–free buildup. Tape Features:

  • Linerless, self–bonding, insulating tape
  • Ethylene propylene base
  • Flame retardant
  • Physical and electrical properties unaffected by degree of stretch
  • Uniform tape unwind from roll
  • Small roll size (OD)
  • Five year shelf life
  • Stable over wide application temperature range
  • W eather Resistant

Applications

  • Primary insulation for cable splices and terminations
  • Moisture–sealing and insulating electrical connections
  • Bus bar insulation
  • Moisture–sealing of cable ends
  • Motor leads
  • W ire and cable jacket repair Data: Physical and Electrical Properties Physical Properties Color Black Thickness 30 mils ASTM D–4325 (0.762 mm) Tensile Strength 250 psi ASTM D–4325 (1.72 MPa) Ultimate Elongation 1000 % ASTM D–4325 Operating Temperature 90°C ASTM D–4388 (194°F) Emer gency Overload 130°C ASTM D–4388 (266°F) Thermal Resistivity 300°C 3M Transient cm/watt Ozone Resistance Passes ASTM D–4388 Heat Resistance Passes ASTM D–4388 UV Resistance Passes ASTM D–4388 Flame Resistance Passes IEEE Std 27–1974 ANSI C37.20C 74 Electrical Properties Dielectric Strength ASTM D–4325 750 V/mil Original (29.5 KV/mm) ASTM D–4325 750 V/mil 24 hrs in H2O (29.5 KV/mm) ASTM D–4325 730 V/mil 96 hrs @ 23°C (28.7 KV/mm) 96% RH Volume Resistivity ASTM D–4325 Original >1015 ohm–cm Aged 96 hrs >1014 ohm–cm @ 23°C 96% RH Dielctric Constant ASTM D–4325 3.5

The high–voltage corona resistant tape must be supplied without a liner and based on ethylene propylene rubber and be capable of emergency operating cable temperature of 130°C. The tape must be capable of being applied in either stretched or unstretched conditions without resulting in loss in either physical or electrical properties. The tape must not split, crack, slip or flag when exposed to various environments (indoors or outdoor). The tape must be compatible with all synthetic cable insulations and have a shelf life of five years. The tape must be flame retardant. Engineering/Architectural Splicing and terminating solid dielectric cables shall be done in accordance with drawings engineered by the splice material manufacturer such as the 2047 Series available from the 3M company. Installation Techniques Scotch 2242 Electrical Tape should be applied in successive half–lapped level wound layers until desired buildup is reached. This tape should be applied like any rubber tape: that is, the side of the tape wrapped inside the roll should be applied ouside on the splice. (Tacky side up.) This will help prevent the roll from getting progressively further away from the work area. To eliminate voids in critical areas, highly elongate 2242 Tape. Stretch tape in these critical areas just short of the breaking point; doing so will not alter its physical or electrical properties. In less critical areas, less elongation may be used. Normally

2242 Tape is stretched 3/4 of its

original width in these critical areas. Always attempt to half–lap to produce a uniform buildup. Shelf Life Scotch 2242 Electrical Tape has a 5–year shelf life (from date of manufacture) when stored under the following recommended storage conditions. Store behind present stock in a clean dry place at a temperature of 70°F and 40 to 50% relative humidity. Good stock rotation is also recommended. Availability Scotch 2242 Electrical Tape is available in 3/4 in. by 15 ft, and 1–1/2 in. by 15 ft rolls from your electrical distributor.
