Electronic grade magnesium hydroxide - Hefei A&H new materials technology co., ltd

Advantage

Excellent dispersibility
Good weather resistance
Efficient thermal conductivity
High thermal stability
High electrical insulation performance

The D120 magnesium hydroxide for chip packaging developed by Hefei A&H New Material Technology Co., Ltd. is mainly used in various fields such as chips, nuclear power plants, rail transportation, medicine, military industry, and mobile phone glass. Its mid to high end products have been monopolized by developed countries such as the United States and Japan, seriously restricting the development of related industries in China, especially in the field of chip production.

At present, the country is vigorously producing and developing chips, among which the high-end magnesium hydroxide used is affected by the international environment and faces the danger of being cut off from foreign supply. Therefore, there is an urgent need for domestic products to effectively replace foreign products.

A leading enterprise in the domestic communication industry came to Hefei to cooperate with us and proposed a demand for our products. The products we provided have been verified by them and are the only ones in China that can meet production needs. They can completely replace foreign products and fill the domestic gap.
