What are the functions of magnesium oxide in the rubber industry?

Magnesium Oxide, an excellent partner in the rubber industry! In today's society, rubber products have a wide range of applications, from tires to wires and cables, everywhere. Magnesium Oxide plays a crucial role in the rubber industry.

The world of rubber is rich and diverse, including general-purpose rubber, styrene butadiene rubber, butadiene rubber, and so on. Among these rubbers, magnesium oxide exhibits multiple effects, not only as a promoter but also as an activator, contributing to the improvement of rubber performance. It can significantly increase the crosslinking density of rubber, thereby optimizing its physical properties. Especially for butyl rubber and chloroprene rubber, the activity of magnesium oxide becomes a key indicator. Its high activity greatly enhances the crosslinking degree of rubber, endowing products such as bottle stoppers with superior physical properties.

In addition, the charm of magnesium oxide lies in its great specific surface area and excellent chemical activity. It is an important raw material for high-performance fine inorganic materials, electronic components, inks, and harmful gas adsorbents. Magnesium oxide can also transform high-density fine-grained ceramics or multifunctional magnesium oxide films. Meanwhile, its excellent sintering performance makes it easy to composite with polymers or other materials.

Although the amount used in rubber is relatively small, the influence of magnesium oxide on the degree of vulcanization cannot be underestimated. It enhances the flowability and oxygen resistance of rubber, while also enhancing its tensile strength and impact resistance. In chloroprene rubber, magnesium oxide plays an important role as a curing agent. It can reduce the activity of zinc oxide, delay the curing rate, and effectively prevent early cross-linking. In addition, magnesium oxide also acts as an acid receptor, cleverly avoiding the problems of coking and cyclization. Usually, magnesium oxide is added in the early stages of mixing to maximize its effectiveness.

Magnesium oxide exhibits excellent alkali resistance and electrical insulation in high-temperature environments, as well as high coefficient of expansion and thermal conductivity, as well as good light projection. These characteristics make it shine in fields such as adhesives, plastics, paint, and paper fillers. In the field of medicine, magnesium oxide also has important applications as an antacid and laxative, providing assistance in the treatment of gastric acid overload and duodenal ulcers. In industries such as ceramics, glass, and advanced insulation materials, magnesium oxide also occupies an important position.

In summary, magnesium oxide plays a crucial role in the rubber industry and many other fields, bringing countless conveniences to our lives.
