Low friction coefficient LSZH jacket material, easy for on-site construction of fiber optic cable:
Waterproof and UV-resistant: Green environmental protection materials with a special molecular structure are used to ensure ultra-low water absorption. Special ultraviolet absorber, so that the product has a good anti-ultraviolet function.
If the cable is used in some special areas, such as areas with a lot of rainy seasons or areas with high humidity, mold tends to grow on the cable material. While ATP's raw materials LSZH can effectively prevent the growth of Mildew.
Formulation technology of Low Friction LSOH:
Low-smoke halogen-free flame retardant polyolefin cable material is usually composed of polyolefin blend resin plus flame retardant filler aluminum hydroxide, magnesium hydroxide, and some appropriate amount of antioxidant added to improve heat resistance life. Sometimes in order to reduce the amount of smoke generated during combustion, some smoke inhibitors are added, such as vanadium, nickel, molybdenum, iron, silicon, nitrogen compounds. The flame retardant mechanism is: when burning, the flame retardant fillers aluminum hydroxide and magnesium hydroxide will release crystal water and absorb a lot of heat; at the same time, the dehydration reaction will generate a lot of water vapor, which can dilute the flammable gas, thereby To prevent combustion, in addition, a layer of non-melting and non-combustible oxide hard shell will be formed on the surface of the material, blocking the channel for the reaction between the polymer and the external thermal oxygen, and finally the material is flame-retardant and self-extinguishing.
The balance of LSOH flame retardancy and physical and mechanical properties:
Low-smoke halogen-free flame retardant polyolefin cable material should have good flame retardancy, aluminum hydroxide and magnesium hydroxide in the formula must have a large filling amount, usually more than 150 parts, and a large number of inorganic flame retardants Filling will inevitably lead to significant deterioration of the material in terms of physical and mechanical properties, electrical properties and extrusion process properties. In order to solve the balance of its flame retardancy and physical and mechanical properties, so that the material can fully meet the technical requirements of the final use, the commonly used methods are: on the one hand, the polyolefin material is modified and grafted to improve the extreme, On the other hand, the surface of inorganic flame retardants is chemically modified, usually treated with a coupling agent.
