Ancor's adhesive lined tubing is superior to conventional heat shrink tubing.Cross Linked polyolefin tubing is much stronger than PVC tubing and will not burn like PVCHeat activated adhesive lining provides impervious seal to saltwater, oil, acids, and sunlight as well as providing strain reliefHighest shrink ratio—shrinks to 1/3 of original sizeShrinks at 257F / 125COperating temperature range of -40C to 110CUL 224Tech Tip: Properly Shrinking Heat Shrink TubingTo properly shrink heat shrink tubing, start by selecting a heat source that will apply the appropriate temperature. Heat shrink tubing will state the shrink temperature, while heat tools are rated based on flame temperatures. Once a heat tool is selected, apply heat gradually to avoid shrinking the tubing inconsistently or burning the tubing. Additionally, continually moving the heat source along the length of the tube will reduce the likelihood of burning the tubing during installation.
