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.
