The method of usage
In the use process, in order to ensure the heat shrinkable sleeve can complete contraction in place, the use of forced air oven
thermostat, and the shrinkage temperature control in 125℃. In particular, when the heat shrinkable sleeve is put into the oven, oven
temperature has a downward trend, to reach the set temperature requires a certain amount of time. At the same time, the heat
shrinkable sleeve to achieve the ultimate shrinkage temperature also needs a certain time by hot air circulating in the oven.
Therefore, we must make oven reach the set temperature and keep the temperature for 3 minutes, heat shrinkable sleeve can
complete contraction in place
