Overview of the Cable Industry
With the continuous growth of the global market and the stable development of China’s macro economy, China’s wire and cable industry has also achieved rapid development. With its excellent product quality and cost performance advantages, the export volume of the wire and cable industry continues to grow, and the export scale of China’s wire and cable industry is steadily expanding. In this regard, we cannot ignore the important role played by magnesium hydroxide.
The Flame Retardant Principle of Magnesium Hydroxide in Cables
Magnesium hydroxide is an excellent environmentally friendly flame retardant that can avoid some safety issues that arise during the use of cables. Its principle is to absorb a large amount of heat through decomposition, and the water generated can isolate air. The magnesium oxide generated after decomposition is a good fire-resistant material, cutting off the supply of oxygen, preventing the flow of combustible gases, and helping to improve the ability of resin to resist flames. Moreover, the thermal decomposition temperature of magnesium hydroxide is as high as 330°C, so its flame retardancy is very superior as a flame retardant. Moreover, it does not produce corrosive halogen gas or harmful gas during use, and has the characteristics of smokeless, non-toxic, non-dripping, non-volatile, long-lasting effect and so on.
The Benefits of Adding Magnesium Hydroxide to Cable Sheath
Ze Hui has found through research that adding magnesium hydroxide to cable sheath also has the following benefits:
The price of magnesium hydroxide is low. Tests have shown that under the premise of achieving the same flame retardancy effect, using Mg(OH)2 costs half as much as using Al(OH)3.
Different manufacturers’ products may also affect experimental results. Since its establishment, Ze Hui Magnesium Base has been committed to researching and producing high-quality, high-content, high-whiteness and high-activity magnesium compound products that are recognized by customers.
