At present, global magnesium oxide is mainly used in medicine, food, plastics, paints, coatings, rubber, cables, feed, ceramics and other fields. Hebei Messi Biology Co., Ltd. pointed out that China’s magnesium oxide consumption structure and demand market in 2024 are mainly the following:
(1) Plastic field
Magnesium oxide is widely used to fill polyvinyl chloride (PVC), polyethylene (PEA, polypropylene (PP) and other resins. In plastic processing, it can reduce the shrinkage rate of resins and control the degree of elasticity. It can also improve the dimensional stability of plastic products, improve the processing performance of plastics, improve the heat resistance of plastic products, and reduce the cost of plastic products.
(2) Papermaking field
As a filler for papermaking, magnesium oxide has high opacity and glossiness, and has uniform particle size and strong color retention. It can replace the previous talc and kaolin, greatly reducing the production cost of paper.
(3) Coating field
Magnesium oxide can greatly reduce the cost of coatings in coatings. It is the main body color. It can enhance the deposition and permeability of primers on the surface of the base layer and improve the coating Improve the water resistance and mechanical strength of materials, and improve the chemical resistance, gloss, brightness, color and other properties of coatings.
(4) Rubber field
As one of the earliest and largest fillers used in the rubber industry, magnesium oxide is filled in large quantities in rubber products. It can not only increase the volume of the products, but also save expensive natural rubber or synthetic rubber, thereby reducing costs.
Compared with developed countries, the current application of magnesium oxide in China is mainly primary products, while the real value of magnesium oxide application is its deep-processing products. At present, the production and application of high-end ultrafine magnesium oxide in the world are mainly concentrated in the United States, Western Europe and Japan, while China’s ordinary magnesium oxide products are in excess and there are few high-value-added products, which cannot meet the needs of the world market and the high-end market in China, resulting in a large number of high-priced imported ultrafine magnesium oxide products. Hebei Messi Biology Co., Ltd. stated that ultrafine high-purity magnesium oxide will be the biggest demand of the magnesium oxide industry in the future.
