      1. When shrinking the heat-shrinking sleeve, use equipment made for this specific operation such as, for example, guns or hot air tunnels.<\/li>\r\n \t
      2. Shrink the sleeve starting at one end, the most critical part, and then proceed slowly to the opposite end. This method avoids the formation of air bubbles between the inner wall of the heat shrink sleeve and the object it covers.<\/li>\r\n \t
      3. In the event that the object to be covered is made of metal or a good heat conductor, it is advisable to preheat the object to avoid “cold areas”, so as to allow a perfect and soft adaptation of the heat-shrinking sleeve.<\/li>\r\n \t
      4. In order to avoid overheating of the heat shrink sleeve, ensure there is regular heat distribution. Excessive overheating of the material during the shrinking process can cause bubbles, discoloration and in some cases even breakage of the heat-shrinking sleeve.<\/li>\r\n<\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

        \n\t\t\t\t\t\t\t\tThe use of heat-shrinkable sheaths with internal thermal-fuse adhesive<\/b> is mainly recommended in the following applications : \n
          \n
        1. When the part to be protected is located in a very humid environment due to the presence of water, snow or other particularly severe atmospheric agents. The internal thermal-fuse adhesive, which melts during the heating and shrinkage phase, completely envelops the object to be protected, making it watertight.<\/li>\n
        2. When there is a need to improve the sealing between the electric cable and its connector, or between several electric cables and the multi-polar flying connector. This use of heat-shrinkable sheaths with an internal thermal-fuse adhesive is quite useful in minimizing any interruptions in the electrical connections between devices, which in some cases, and especially in certain sectors, can be particularly damaging.<\/li>\n<\/ol>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

            MEDIUM THICKNESS POLYOLEFIN HEAT SHRINK SLEEVE<\/strong><\/p>\n

            The medium thickness TTPAMS sleeve is a flexible<\/strong> heat shrinkable sleeve with internal adhesive. The inner surface of the sleeve is coated with a hot-melt adhesive that melts around the object during shrinkage, in<\/strong> order to protect it from any infiltration of water or moisture. The high shrinkage ratio makes this sleeve suitable for protecting<\/strong> particularly irregular<\/strong> objects due to high dimensional differences. Ideal in all applications where a high degree of protection is required. Furthermore, the high thickness of the wall, after shrinking, makes this sleeve particularly suitable for uses where high mechanical protection<\/strong> is required.<\/p>\n
