Scotch Rubber Splicing Tape 23 Data Sheet February 2017 Description Scotch Rubber Splicing Tape 23 is a highly conformable, self-fusing EPR (Ethylene Propylene Rubber) based, high-voltage splicing tape. It is a non-vulcanizing, shelf- stable tape with excellent electrical properties. Scotch 23 tape can be used as an insulation for low-voltage applications as well as an insulation for splices up to 69,000 volts. For RoHS information, please visit www.3M.com/ROHS Agency Approvals & Self Certifications Tape Features Can be used to splice and terminate cables whose emergency overload temperatures can reach 266F (130C) Based on Ethylene Propylene Rubber (EPR) Physical and electrical properties are unaffected by the degree of stretch Self-fusing tape Excellent electrical properties A special polyester liner which will not stick to the tape upon unwind Compatible with all solid dielectric cable Insulation: 1. Polyethylene (high and low density) 2. Cross-linked Polyethylene (XLP) 3. Polyvinyl Chloride (PVC) 4. Butyl Rubber 5. Ethylene Propylene Rubber (EPR) 6. Oil-based rubber Applications Primary electrical insulation for splicing cable from 600 volts through 69,000 volts on all solid dielectric cables Primary insulation for building stress cones on cables up to 35,000 volts on all solid dielectric cables Jacketing on high-voltage splices and terminations Moisture sealing electrical connections Bus bar insulations End sealing high-voltage cables 1 of 5 3M Scotch Rubber Splicing Tape 23 Typical Properties Not for specifications.

Scotch Rubber Splicing 23 tape may be applied in either the stretched or unstretched condition without resulting in loss in either physical or electrical properties. The tape is split resistant, crack resistant, slip resistant and flag resistant when exposed to various environments (indoor or outdoor). It is compatible with synthetic cable insulations. Scotch 23 Tape has a dissipation factor of less than 5% at 266F (130C), and a shelf life of 5 years. 2 of 5
