The stability and safety of power transmission and signal transmission are crucial in modern urban construction and industrial development. As the "blood vessel" of energy and information, the performance of cables is directly related to the normal operation of production and life. However, traditional cables are prone to producing large amounts of thick smoke and toxic halogen gases in extreme situations such as high temperatures, short circuits, or fires, which not only hinder escape and rescue, but also pose serious hazards to human health and the environment. How to balance the efficient conductivity and safety and environmental protection characteristics of cables. Professional and efficient low smoke halogen-free magnesium hydroxide cables have emerged, becoming a benchmark product for technological innovation in the industry.
1、 Industry pain point: Safety hazards of traditional cables
Although ordinary PVC cables are low-cost, they release toxic gases such as hydrogen chloride and smoke when burned. According to statistics, 80% of casualties in fires are caused by suffocation or poisoning caused by toxic smoke. In addition, traditional flame retardants often contain halogens, which can delay combustion but cannot solve the problems of smoke and toxicity. With the tightening of global environmental regulations (such as the EU RoHS directive and the Chinese GB/T 19666 standard), the market has put forward higher requirements for the flame retardancy, low smoke, and non-toxic properties of cables.

2、 Technological breakthrough: Magnesium hydroxide empowers cable upgrade
The core innovation of professional and efficient low smoke halogen-free magnesium hydroxide cables lies in the use of high-purity magnesium hydroxide (Mg (OH) ₂) as a flame retardant. Magnesium hydroxide decomposes and absorbs heat at high temperatures (decomposing into magnesium oxide and water at 340 ℃), which can effectively reduce the combustion temperature. The water vapor produced by its decomposition can also dilute combustible gases, achieving dual flame retardancy. Compared to traditional materials, magnesium hydroxide has three major advantages
Absolutely environmentally friendly and halogen-free: free of halogen elements such as chlorine and bromine, only non-toxic water and magnesium oxide are released during combustion, fully meeting international environmental standards.
Ultra low smoke density: The smoke generation is only 1/10 of that of PVC cables, and the light transmittance exceeds 60% (tested according to IEC 61034), ensuring clear visibility during a fire
Efficient flame retardant and temperature resistant: oxygen index ≥ 32 (GB/T 2406 standard), can withstand extreme environments from -40 ℃ to 105 ℃, suitable for high safety scenarios such as subways and hospitals.
3、 Performance Test: Data Witness Strength
The cable specific magnesium hydroxide produced by magnesium magnesium industry, a leading enterprise in flame retardants, has shown excellent performance in multiple key indicators according to a third-party testing report
Flame retardancy: Passed UL 94 V-0 level vertical combustion test, self extinguishing within 1 second of ignition;
Smoke density: far superior to the national standard requirement of 200;
Toxicity index: CO/CO ₂ release level below 0.1, meeting theater level safety requirements;
Electrical performance: The conductor resistance and insulation strength are better than the GB/T 12706 standard, and the transmission efficiency is improved by 15%.
Choosing magnesium hydroxide flame retardant for special cables and cables in the magnesium industry is not only a technological upgrade, but also a reflection of corporate social responsibility:
Whole life cycle cost optimization: Although the initial cost is 20% higher than PVC cables, the service life is extended by more than 50% and maintenance costs are reduced by 30%.
Green certification premium: Priority procurement for construction projects that have passed relevant certifications, helping developers increase brand premium
Policy compliance and worry free: Meet the mandatory environmental protection requirements for public facility cables in the revised draft of China's Fire Safety Law in advance.
