Description
The 3M 7000034850 Scotch 23 rubber splicing tape is a premium, 30 mil self fusing Ethylene Propylene Rubber (EPR) tape supplied on a removable polyethylene liner for easy handling. Specially made for electrical splice and termination applications up to 69 kV, this highly conformable rubber splicing tape provides primary insulation in cable jointing and repair. It resists temperatures to 194°F with an emergency overload capability to 266°F, and meets ASTM and RoHS requirements. The special polyester liner prevents sticking during unwind, improving application speed and uniformity. For higher continuous temperature applications consider the related 3m scotch 130c product series as an alternative.
Product Features and Benefits
Self fusing EPR formulation
3m scotch 130c Ethylene Propylene Rubber backing fuses to itself to form a homogeneous insulating mass without adhesive, ensuring reliable primary insulation for cable splices..
30 mil premium thickness for heavy duty insulation
Scotch 23 rubber splicing tape is thick 0.76 mm (30 mil) construction and provides robust dielectric strength suitable for medium voltage splice insulation up to 69 kV.
High conformability and special liner
High conformability permits tight wrapping over irregular profiles and terminations while the polyester liner prevents sticking up during unwind for consistent application.
Thermal & standards performance
Rated to 194°F (90°C) with emergency overload to 266°F (130°C) and halogen free per IEC 612492-21; ASTM D4388 Type III compatible and RoHS compliant. Specified shelf stability (5 years) simplifies inventory management for field and shop use.
Frequently Asked Questions
How do I use 3M 23 rubber splicing tape?
Wrap the self fusing EPR tape with recommended overlap and tension to build required insulation thickness and allow the tape to fuse to itself.
Is 3M 23 rubber splicing electrical tape suitable for 69kV splices?
Yes, Scotch 23 is specified for primary insulation on cable splice and termination applications up to 69 kV per ASTM D4388 Type III.
What temperature limits apply to Scotch 23 rubber splicing tape?
Continuous operating temperature is 194°F (90°C) with an emergency overload rating of 266°F (130°C).
How does Scotch 23 differ from other rubber splicing tapes and how to use rubber splicing tape correctly?
Scotch 23 is thicker (30 mil) and self fusing with a non sticking liner for clean application; apply with consistent overlap and tension to avoid voids.
