HEAT-SHRINK RING TERMINALS

$0.01

The insulation of HEAT SHRINK RING (SR) and BUTT (SB) consists of a special double layer, high-density polyethylene and polyolefin adhesive. After crimping, the insulation is heated to shrink the outer polyethylene layer and to melt the inner polyolefin liner. This action squeezes out gas while filling all voids resulting in a sealed connection.

Description

APPLICATIONS
Automobile, water pump, vessel, home appliance (washer, kitchen), anti-vibration, anti-dust applications.
APPLIED WIRE
Most wires are acceptable except when insulated with silicon rubber, fiber glass, teflon (FET, TFE etc.) and fluororubber.
HEATING TO SHRINK
  • Apply heat of 120°C on the insulator. Do not apply flame directly. Do not make excessive shrinkage, as such, by electric furnace of 140°C, for over 5 minutes.
  • Apply heat from the center of the butt moving towards the end while rotating the butt.
  • Application of heat is sufficient when the inner adhesive melts and slightly protrudes from the outer insulator.
NOTE
  • Keep out of direct sun light and hot places to avoid premature shrinkage.
  • Do not make excessive shrinkage to avoid breakage on the insulator.
