We sincerely invite you to attend the Plast Eurasia Istanbul 2024 to be held at Türkiye! This exhibition will showcase the latest products, technologies and industry trends, and is a great opportunity to learn about industry dynamics, exchange and cooperate.

The surface modification of magnesium hydroxide is to improve its compatibility and dispersion in the polymer base material, thereby improving the mechanical properties and flame retardant efficiency, while reducing environmental pollution and optimizing the overall performance of the product. Here are seven main reasons why surface modification of magnesium hydroxide should not be ignored:

In recent years, fire accidents caused by polymers have attracted great attention from all walks of life, and the research and development of flame-retardant polymers has become a hot topic. At present, organic flame retardants used in the market have hazards such as large smoke production and toxic smoke, which are subject to legal restrictions in Europe, the United States, Japan and my country. Therefore, inorganic flame retardants have received great attention.

Magnesium hydroxide (Mg(OH)₂) is a white crystal or powder with weak alkalinity and hygroscopicity. The part soluble in water is completely ionized, and the saturated solution concentration is 1.9 mg/L (18°C). Its preparation methods include brucite grinding method and chemical synthesis method (such as calcium hydroxide method, ammonia method, sodium hydroxide method).

In plastic filling modification, the performance parameters of calcium carbonate have an important impact on the quality and processing technology of the final product.

Calcium carbonate (CaCO₃), as an indispensable filler in the plastics industry, has become a key component in plastic products with its excellent performance and economy. It not only improves the performance of plastics, but also effectively reduces production costs, so it plays a vital role in the field of plastic processing.
