Precautions for Purchasing Heat Shrinkable Tubes

When it comes to heat shrinkable tubes, many people are familiar with them. The heat shrinkable tubes can be seen in all kinds of fishing rods, lamps, wires and cables used in daily life. They are made of various materials, have good flexibility, and are very comfortable to hold. Of course, it is also used in other fields, such as garden tools, low-voltage indoor busbar copper bars, connectors, and wire harness signs.


1. Precautions for purchasing heat shrinkable tubes


The purchase of heat shrinkable tubes is naturally to choose good quality product, and the issues to be paid attention to should be considered. First of all, it should be noted that the tube has various materials, such as PVDF material, EVA material, PET material, silicone and other materials. When selecting, it should be selected according to the actual use situation.


Secondly, pay attention to the characteristics of different materials. Heat shrinkable tubes have a special function of shrinking when exposed to heat, so those that cannot shrink when heated are not called heat shrinkable tubes.


The heat shrinkable tube can shrink when heated to a certain temperature, which is more convenient to use and has high temperature resistance; PET material is better than PVC and EVA, with better heat resistance, electrical insulation, mechanical properties and other advantages such as non-toxic, easy to recycle and more environmentally friendly; PVDF material has the advantages of softness, low temperature shrinkage, insulation, corrosion resistance, wear resistance and so on. Finally, pay attention to the after-sales service of the manufacturer, and the after-sales service should be meticulous and thoughtful, so that the purchase will be more worry-free.


In addition, select high-quality manufacturers. Hont Electrical Co.,Ltd was established in 1997, mainly responsible for the production and sales of nylon cable ties and other cable accessories, with a factory area of 45,000 square meters, with an annual export volume of more than 30 million US dollars. HONT cable ties are now sold to 140 countries and regions. We have cooperated with major cable tie distributors in EU, NA, SA countries for more than 10 years. The company invests a lot of money in product research and development every year, mainly for product development and related certification. At present, it has more than 10 patents for innovative application products, which only HONT can provide. We have passed product certifications such as UL, CE, ROHS, REACH, factory ISO9001 system certification. As a BSCI member, we can accept BSCI inspection.


2. Application of heat shrinkable tube in high frequency cable joint


High frequency cables are an important part of the power carrier channel. The quality of the cable joints will directly affect the quality of the power carrier communication. After the advent of the shrink tube, it has brought new life to the joint processing of high frequency cables. The use of heat shrinkable tube as the outer sheath has the advantages of simple operation, great sealing performance, aging resistance and tensile strength. It is widely used to test the insulation resistance and loop resistance of the processed cables. All indicators should meet the standards. Otherwise, they should be disassembled and remade.
