Product introduction

The particle size of superfine magnesium hydroxide is between 100nm and 1000nm. As an important chemical product and intermediate, it has been widely used in ceramic materials, environmental protection, medicine and other fields. Recent studies have shown that because of its high decomposition temperature, good thermal stability, non-toxic, smoke-free and smoke suppression (most of its properties are better than aluminum hydroxide), it is widely used in transportation, construction, electronics and electrical, chemical and other fields, especially in the application of flame retardants, and plays an important role in national economic construction, safety and environmental protection.

Product characteristics

When using magnesium hydroxide as flame retardant, there are the following disadvantages: first, the flame retardant efficiency is relatively low. Therefore, higher addition amount is required; Second, its surface naturally presents the nature of "hydrophilic and oil repellent", which is highly concentrated in organic matter. It is difficult to disperse uniformly in the polymer. If magnesium hydroxide without surface treatment is used as filling material, other properties of polymer materials (such as mechanical properties and processability) will be seriously affected. Therefore, in order to maintain the excellent performance of polymer materials and reduce the adverse effect of magnesium hydroxide as an additive on the product performance as much as possible, it is usually necessary to superfine magnesium hydroxide. After ultra-fine treatment, magnesium hydroxide can improve its dispersion in the polymer, change its natural "hydrophilic and oil repellent" surface properties, reduce the impact of magnesium hydroxide on the processing and mechanical properties of polymer products, and even improve the properties of the polymer.
