halogen-free environmentally friendly flame retardant heat s
The halogen-free of halogen-free environmentally friendly flame retardant heat shrink tube does not mean that it does not contain halogen elements, but refers to the content of halogen elements in electronic products that meet relevant regulations. Halogens include fluorine F, chlorine Cl, bromine Br, iodine I, and astatine At. The standard content of each country and region is slightly different. The material of the heat shrinkable tube polyolefin halogen element must meet the relevant standards to become halogen-free environmentally friendly flame retardant heat shrink tube.
After talking about halogen-free, let's talk about the flame-retardant performance of this halogen-free environmentally friendly flame retardant heat shrink tube. This kind of heat-shrinkable tube used to be a widely used flame-retardant material. It is a flame-retardant mixture with excellent flame-retardant properties composed of halogen-containing polymers or a combination of halogen-containing flame retardants. In fact, it is difficult to find a kind of The real halogen-free flame retardant flame retardant, now we use the emerging phosphorus-based halogen-free flame retardant, microencapsulated red phosphorus flame retardant to achieve the desired flame retardant effect, as long as it can meet the relevant regulations halogen-free environmentally friendly flame retardant heat shrink tube.
With the advancement of science and technology and the development of society, people pay more and more attention to green products and advocate the protection of the natural environment. The European Union and other developed countries have formulated strict environmental protection regulations. The RoHS directive clearly requires the elimination of lead, cadmium, slip agents and composite antioxidants in electronic and electrical products, as well as heavy metals such as mercury, hexavalent chromium, and polybrominated biphenyls (PBB). Environmental substances. It is precisely because of this series of regulations that, as one of the indispensable parts of electronic and electrical products, heat shrinkable tubes must comply with the corresponding environmental protection regulations at home and abroad, and their various material element indicators. The market for halogen-free environmentally friendly flame retardant heat shrink tube is gradually being opened, and it has gradually taken up the leading position in the market that originally belonged to the cheap product of PVC heat-shrinkable tubing and has become the main hot-selling product in the market.
The halogen-free environmentally friendly flame retardant heat shrink tube of Suzhou Feibo Cold & Heat-shrinkable Products Co., Ltd. is rich in colors and specifications, but one thing needs to be added. Flame-retardant heat-shrinkable tubing has many different flame retardant grades, you are buying Be sure to clarify the requirements with the customer service staff. Some of them need to be customized, otherwise we generally default to package and ship conventional products.
