REPL RIMTU Medium Wall Heat Shrink Tubing (Uncoated)
Product overview
REPL RIMTU Medium Wall Heat Shrink Tubing (Uncoated)
REPL RIMTU Medium Wall Heat Shrink Tubing (Uncoated) are unlined heatshrinkable tubes used for environmental sealing of plastic and paper insulated cable joints rated up to 1kV.
RIMTU Part Numbers: 9/3, 12/4, 22/6, 30/8, 40/12, 52/16, 63/19, 80/22, 100/30, 120/ 34, 140/40, 160/50, 180/60.
These tubes are made from thermally stabilised, cross linked and weather resistant polymeric material and have a nominal shrink ratio of 3:1 and an unlimited. The tubes can be supplied in a coated form – hot melt adhesive lined (RIMTA) depending on the application.
