The shrinkage test of heat shrinkable casing is divided into two cases.
1.85 degree C heat shrinkable casing test method:
Cut two section 10 centimeters length heat shrinkable tube, put boiling water for 1~2 minutes to get out. Use the tool ruler to measure the transverse and longitudinal length. Respectively: the length is /10, and the shrinkage rate is obtained.
(this method applies PVC heat shrinkable casing and PET heat shrinkable casing and some 105 centigrade heat shrinkable sleeves)
2.105 centigrade heat shrinkable casing test method:
Cut two section 10 cm length heat shrinkable tube and put it at 180 centigrade high temperature oven. Use the tool ruler to measure the transverse and longitudinal length. Respectively: the length is /10, and the shrinkage rate is obtained.

Product features: excellent environmental protection, insulation, stable performance, low shrinkage temperature, fast shrinkage and so on.
Product features: heat shrinkable casing has a special function of heat shrinkable. It can shrink over 98 degrees centigrade, and it is convenient to use. Has excellent flame retardant, insulation, environmental protection, soft, stable performance, low shrinkage temperature, has the advantages of quick shrinkage; resistant to high temperature performance, no two contraction. Can play a role and beautify the anti-counterfeiting packaging, and coated articles can play insulation, moisture-proof, dustproof and anti-corrosion, etc. effect;
Scope of application: heat shrinkable tube is widely used in electrolytic capacitors, inductors, various rechargeable battery monomer, combination packaging, all kinds of curtain rod, shower curtain rod, a hanging rod, a mop rod, a broom handle, tool rod, a telescopic rod, garden tools, bar tubular articles covering. It can be used for low indoor bus copper bar, wire harness connector, identification, insulation coating. High efficiency, less investment in equipment and less comprehensive cost. It is used for the coating of the lamp, the LED pin, and the package of the guitar and the packing bottle.
