Built-in mastic cold shrink tube for electronic industry

Communication With Built-in Mastic Cold Shrink Tube：This cold shrink tubing？（Cold Shrink Tube,Cold-shrink tube） is widely used in the electronics industry for internal blocking of PCB boards to reduce the effects of dust and moisture and to prevent tin sticking and oxidative corrosion. Built-in mastic cold-shrinkable sleeve is a kind of pre-mastic silicone rubber insulating tube with mastic expansion in the extractable support tube, in the use of only need to locate after the extraction of the support tube can be used, the use of its radial pressure to form a wrapping, and the mastic cable with the formation of a tight protection, to play a role in waterproofing, moisture-proof, insulating and sealing.
