There are two cases of shrinkage test of heat shrink tubing.

1.85 ° C Heat Shrink Tubing Test Method:

Cut two sections of 10 cm length heat shrink tube, placed boiling water 1 to 2 minutes to remove. Measure the horizontal and longitudinal lengths with tooltips. Respectively: length / 10, draw shrinkage.

(This method applies to PVC heat shrink tubing and PET heat shrink tubing and part of the 105 ℃ heat shrink tubing)

2.105 ℃ heat shrink tubing test method:

Cut two sections of 10 cm length heat shrink tube, placed 180 ℃ high temperature oven out. Measure the horizontal and longitudinal lengths with tooltips. Respectively: length / 10, draw shrinkage.

Product color: black, transparent, red, white, yellow, blue, green, etc., according to customer requirements other colors;

Features: excellent environmental protection, insulation, stable performance, low shrinkage, shrink fast and so on;

Features: Heat shrink tubing with a special function of heat shrinkage, heating above 98 ℃ can shrink, easy to use. It has the advantages of excellent flame retardant, environmental protection, insulation, softness, stable performance, low shrinkage temperature and fast shrinkage. The product has high temperature resistance and no shrinkage. It can play the role of anti-counterfeiting and beautification packaging, Covering the items can play insulation, moisture, corrosion, dust and other aspects of the effect;

Applications: Heat shrink tubing is widely used in electrolytic capacitors, inductors, all kinds of rechargeable battery monomer, combination of packaging, all kinds of curtain rod, shower rod, hanging rod, mop bar, broom handle, tool rod, telescopic rod, Garden tools, braces and other tubular objects covered. And can be used for low-voltage indoor bus copper, connectors, wiring harness logo, insulation coating. High efficiency, low investment in equipment, comprehensive cost is small. For lighting, LED pin wrap, and guitar, packaging bottle of the package.
