Insulating materials are substances that prevent the flow of electricity. They have a high resistivity, typically ranging from 10 to 10 Ω·m. How do insulating materials fare in terms of flame resistance?

Flame Retardancy of Insulating Boards refers to the ability of insulating materials to resist combustion when exposed to flame or to prevent the continuation of combustion after leaving the flame. As the application of insulating materials expands, the requirement for their flame retardancy becomes increasingly significant. People are improving and enhancing the flame retardancy of insulating materials through various means. The higher the flame retardancy, the better the safety.

With the rapid growth of the national economy and the swift development of the power generation, substation, and electromechanical industries, the demand for insulating tubing materials in China has surged. This has significantly accelerated the development of laminated insulation boards in our country. Currently, some products have reached a high level, particularly the composite insulating paper, which has strong competitiveness in the international market and has made China one of the world's leading producers of insulating materials. Insulating materials are widely used in various fields such as electrical appliances, electronic information, automotive, and aerospace industries, and accordingly, the development of insulating paints, papers, tubes, and boards has also been remarkable. Moreover, in recent years, the innovative applications of insulating materials have gradually become one of the key drivers for China's implementation of sustainable energy solutions.

In recent years, the domestic insulating materials industry in our country has developed rapidly, especially exhibiting a notable cost advantage when compared to overseas manufacturers. As the technical capabilities of domestic insulating materials producers continue to improve, their share in the international market has been increasing, and their competitive edge has gradually enhanced. On a global scale, the producers of laminated insulating materials are primarily manufacturers of insulating laminates. Not only does our country's insulating materials hold a significant advantage internationally, but they have also further boosted the exports of insulating paints, papers, and other insulating materials, propelling the development of foreign trade.
