Application of magnesium carbonate in resin rubber

Hebei Messi Biology Co., Ltd. stated that magnesium carbonate is widely used in various industrial fields such as pharmaceuticals, cosmetics, food, and building materials. There are also examples of its use as a filler for resin rubber. It is recorded that anhydrous magnesium carbonate with a BET specific surface area of ​​1 to 15 m2/g and an average particle size of 1 to 10 μm can be used as a filler for engineering plastics.

food grade magnesium carbonate

Depending on the type of magnesium carbonate, there are cases where transparency is damaged and it cannot be used for applications requiring transparency, or even if transparency is not required, the appearance (aesthetics) is damaged or the colorability is adversely affected. The specific physical properties of magnesium carbonate are related to the transparency when used as a filler. When magnesium carbonate is added to resin (rubber), the transparency is rarely reduced. Therefore, in addition to applications requiring transparency, it can be appropriately used for applications requiring appearance, design, coloring, etc. due to its less impact on appearance and coloring.

When magnesium carbonate is added to rubber, it can improve strength and rigidity while maintaining a high level of transparency. Therefore, magnesium carbonate can achieve both high transparency and high strength and rigidity for a wide range of resins. Such magnesium carbonate can be suitably used as a resin additive [for example, a filler (bulking agent, reinforcing agent) and the like.
