     The development and application of heat shrinkable tubes has brought great convenience and safety to our lives. Therefore, its elasticity is relatively small, and thermal expansion and contraction during operation may cause the interface to produce an odor, so sealing skills are insignificant to prevent moisture infiltration. Heat shrinkable tube is a special polyolefin material, which can also be called EVA material. It has high temperature expansion, soft flame retardant, insulation and anti-corrosion properties. It is suitable for insulation protection with a voltage of less than 600V. When used, the heat shrinkable tube is heated to a high elastic state, a load is applied to expand it, and it quickly freezes while maintaining expansion. making it enter the glass state. This state It became vivid.

     Materials made of decabromo or CPE such as outdoor materials and masterbatch materials are not allowed to be mixed into environmentally friendly heat shrinkable pipe materials without being sorted out and cured: all heat shrinkable materials are batched according to the same formula before production, and the masterbatch is continued. Mixing and granulating make it inconvenient for production in the previous steps. Therefore, the production of masterbatch is the link where cross- contamination is most likely to occur. The following are some points that need to be paid attention to in the masterbatch process. Each bag of material is continuously marked with an environmental protection label; the heat shrinkable tube must meet the requirements of flame retardancy, breakage elongation. etc. In order to meet the performance requirements such as length, tensile strength, and anti-aging, some auxiliary materials used in these pipes such as heat shrink sleeves and heat shrink busbar pipes must not be mixed into environmentally friendly heat shrink pipe materials. A large amount of heat shrinkable material masterbatch is continuously granulated in the same internal mixer. Therefore, the intemal mixer must be cleaned up before it can produce the masterbatch.

     When using the raw materials of environmentally friendly heat shrinkable tubes. the warehouse management personnel must press The list of original and auxiliary information will continue to be checked to ensure that it is correct before release. On the contrary, the recycling and crushing of heat shrinkable materials should be separated from the label, and a single dedicated facility should be provided to cruse environmentally friendly heat shrinkable tube materials: heat shrinkable tubes can be roughly divided into: PVC heat shrinkable sleeves, PET heat shrinkable tubes, and glue-containing heat shrinkable tubes Three types. Among them, PET heat shrinkable tubes have better performance, so they are much better than PVC heat shrinkable tubes in terms of heat resistance, electrical insulation, and mechanical properties. Not to mention, PET heat shrinkable tubes are non-toxic and easy to recycle. , will not cause unnecessary harm to the human body and conditions, and is more in line with the environmental protection requirements advocated.
