Question<\/strong>: How can I calculate the optimal inner diameter of a heat-shrinkable sheath?
Answer<\/strong>: There are several ways to identify the optimal internal diameter to be used to cover a given object:
1) The general principle used is that the internal diameter is chosen in such a way that after vacuum shrinking, it is 20% less than the object to be covered.
2) Having established the diameter of the object to be covered, the width of the flattened heat-shrinking sheath can be determined by applying the formula 1.57079 x diameter.
3) Having established the width of the flattened heat-shrinking sheath available, the diameter of the object to be covered can be determined using the formula 0.6366 x sheath width.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Question: What measures should be implemented to correctly cut heat shrink sheaths?
Answer: When cutting a heat shrink sheath, you have to make sure that the ends are cut with extreme precision. Inaccurate and irregular cutting may cause the heat shrink sheath to break during the shrinking phase.<\/p>\n<\/div>\n<\/section>\n<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Question<\/strong>: What are the most effective methods to use for shrinking a heat shrinkable sheath?
Answer<\/strong>: Heat shrink sheaths must be shrunk starting from one end, the most critical end, and then proceed slowly towards the opposite end. This method avoids the formation of air bubbles between the inner wall of the heat shrink sheath and the object it covers.
To obtain an optimal shrinkage result, it is advisable to use equipment made for this specific operation, such as hot air guns or tunnels.<\/p>\n

In the event that the object to be covered is made of metal or a good heat conductor, the ideal solution is to pre-heat the object to avoid “cold areas”, so as to allow perfect and soft adaptation of the heat-shrinking sheath.<\/p>\n

In order to avoid overheating of the heat shrink sheath, ensure there is regular heat distribution. Excessive overheating of the material during the shrinking process can cause bubbling, discoloration and in some cases even breakage of the heat shrink sheath.<\/p>\n<\/div>\n<\/section>\n<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Question<\/strong>: Can heat-shrinkable sheaths be stored outside warehouses?
Answer<\/strong>: For proper storage of heat-shrinkable sheaths, it is necessary to ensure that they are stored in a cool, dry, clean place but above all far from direct heat sources. The correct storage temperature is 0 – + 40\u00b0C max with a relative humidity of >75%.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
