Ideal Thermo-Shrink ; 2:1 Ratio thin wall heat shrinkable tubing in black color is made of high strength/excellent resilience polyolefin to electrically insulate/protect in-line components, disconnect terminals and splices. It is use to bundle 14 - 8 AWG size wires for very flexible light-duty harnesses. Tubing measures 1/4 Inch diameter x 6 Inch. It has highly flame-retardant property to resist electric shock and is flexible for convenient operation. Tubing starts to shrink at a temperature of 70 deg C. It has 30% eccentricity and 0+/-5% longitudinal shrinkage properties that makes elongation/shrinking easier. Tubing operates within temperature range of -55 to 135 deg C. It can be elongated up to 350% of the original size after aging at 175 degree C for about 168 hours. Tubing has dielectric strength of 20 kilo-Volts/mil and tensile strength of 14 MPa. It can be elongated up to 600% of the original size. Tubing is UL listed and is RoHS compliant. Also known as -Ideal 46-316 Thermo-Shrink 21 Ratio Thin Wall Heat Shrinkable Tubing 1/4 Inc
