PWC421 series Shrink Tubing is a cross linked polyolefin heat shrinkable tubing with an internal meltable sealant. When heated above 110C the tubing will shrink to 25% of its original diameter. As it shrinks, the internal sealant melts and provides a moisture-proof seal for encapsulation of wires, splices, breakouts and components. This tubing is especially of value for applications as a moisture barrier in high humidity and corrosive environments requiring higher shrink ratio.
