Note:
(1)Lateral contraction test method is as follows:
A.Take the heat-shrinkable tube sample 100mm into boiling water (98 & plusmn; 2 ℃) for 30 seconds.
B.Remove the cooling, measured with a number of vernier calipers, and calculated as follows. Shrinkage (%) = [(100 - shrink width) / 100] x 100%
(2)Longitudinal shrinkage test method with transverse contraction.
(3)LHigh temperature shrinkage test method is as follows:
A.LTake the heat-shrinkable tube sample 100mm, placed in a thermostatically controlled and hot air circulation of the oven, (180 & plusmn; 2) ℃ for 15 minutes.
B.LRemove the cooling, measured with a number of vernier calipers, and calculated as follows. Shrinkage (%) = [(100 - shrink width) / 100] x 100%
(4)LColor and specifications can be customized according to user requirements |
|
|
3.Precautions
PET thermal casing products in the transport process should avoid direct sunlight and high temperature, away from heat, should be stored in the ambient temperature <30 ℃ ventilation and dry warehouse, storage period of one year.
