Description
Scotch® Cable Jacket Repair Tape 2234 provides a cost effective and efficient means of covering and protecting damaged sections of cable jacket, thereby extending the life of the cable and reducing down time. The outer layer of the tape is composed of vulcanized CSM rubber to provide outstanding chemical and environmental resistance. The inner layer is composed of flame-retardant mastic and acts as a moisture barrier which provides excellent adhesion to a variety of jacket materials.
Features
- Insulates and protects damaged cable jackets
- Flame retardant
- Good adhesion to cable jacket materials
- Excellent abrasion resistance
- Resistant to heat, oil, ozone, UV and other environmental effects
- Maintains flexibility to -22°F (-30°C)
