SM278-11/4"

Daburn Electronics & Cable 44 Richboynton Road Dover, NJ 07849 Daburn SM278 Shrinkable Polyolefin Tubing - Flexible, Dual Wall Description: DAFLEX SM278 is a flexible, large ratio, heat shrinkable tubing with a meltable adhesive liner. When 120°C is applied, the tubing will shrink to 25% of its supplied size (4:1). Longitudinal shrinkage is 10% maximum. As the outer wall shrinks, the inner adhesive liner melts and flows. When cooled, it offers protection for a variety of electrical applications as well as "sealed-in" protection from chemicals and oils. Because of its large shrink ratio and adhesive liner, it offers excellent protection for cable repairs and retrofitting. Operating Temperature: -55°C to +135°C. Meets or exceeds MIL-I-23053/4 Class 3. UL VW-1, CSA OFT (outer wall only). This series is RoHS II, EU Directive 2011/65/EU compliant. Shelf Life is 3 years. Daburn Cat. No. Nom.
