Zehui deep-rooted for more than 20 years, how to push the high-purity magnesium hydroxide to the forefront of the rubber industry

Over the past two decades, Jiangsu Zehui Magnesium Base has been deeply engaged in the field of high purity magnesium hydroxide, and has successfully pushed this high-performance material to the forefront of the rubber industry by virtue of continuous technological innovation and market insights. As a benchmark enterprise in the domestic magnesium hydroxide industry, Zehui has not only made remarkable achievements in the research and development and production of high-purity magnesium hydroxide, but also played an important role in promoting the sustainable development of the rubber industry. The deep integration of the excellent performance of high purity magnesium hydroxide and the rubber industry will bring unprecedented changes and opportunities for the industry.

High purity magnesium hydroxide plays multiple key roles in the rubber industry:

1. Improvement of Flame Retardant Properties

Heat-absorbing effect: High-purity magnesium hydroxide will decompose when heated, and this process absorbs a large amount of heat, which effectively reduces the temperature of the surface of the rubber material, thus slowing down the burning speed.

Water vapor dilution: The water vapor produced by decomposition can dilute the flammable gases produced when the rubber burns and reduce the speed of flame propagation.

Barrier effect: The magnesium oxide generated by decomposition forms a protective film on the surface of rubber, which can isolate oxygen and prevent further combustion processes. This property is particularly important in critical applications such as wire and cable, rubber seals, etc. and can significantly improve the fire safety of products.

2. Enhancement of physical and mechanical properties

Tensile strength and bending resistance: By adding appropriate amount of high purity magnesium hydroxide, the key indexes of tensile strength and bending resistance of rubber products can be significantly improved. This is mainly due to the good dispersion and combination of magnesium hydroxide in the rubber matrix, forming a more compact network structure and improving the overall strength of the material.

Abrasion resistance and hardness: The addition of high purity magnesium hydroxide also improves the abrasion resistance and hardness of rubber, making rubber products more durable.

3. Facilitation of the vulcanization process

Acid receptor: In the process of rubber vulcanization, high purity magnesium hydroxide can act as the receptor of acid, effectively neutralizing the acidic by-products produced in the vulcanization process. This effect not only accelerates the speed of vulcanization and improves the production efficiency, but also improves the physical and mechanical properties and chemical stability of the vulcanized rubber.

Zehui not only focuses on the deep cultivation of magnesium hydroxide but also actively deepens the cooperation, and now establishes close cooperation with many large domestic rubber industry manufacturers to jointly promote the application and development of high purity magnesium hydroxide in the rubber industry. Zehui believes that through our unremitting efforts and continuous innovation, high purity magnesium hydroxide will play a more important role in the rubber industry and contribute more to the sustainable development of the industry.
