Product Application
Magnesium stearate is an indispensable component in numerous industrial applications such as polymers, polyvinyl chloride (PVC), pencil leads, tablets and cosmetics. It has chemical stability and can be used as a lubricant, anti-sticking agent, mold release agent and heat stabilizer. Therefore, it is of vital importance in many industries.
PVC product stabilizer
In addition to its function as a lubricant, magnesium stearate also serves as a heat stabilizer in the polyvinyl chloride (PVC) industry. When processing polyvinyl chloride, magnesium stearate can provide thermal stability for combustible materials from fuses to imaging equipment, preventing the material from volatilizing and degrading.
Dispersants and lubricants for polymer functional materials
Magnesium stearate has two major functions in the polymer industry: as a dispersant and a lubricant. It helps to disperse the materials better. It can reduce the friction between the machine and the materials. This can enhance stability and improve the quality and functionality of polymer products.
Functional additives for cosmetics and pharmaceutical tablets
Magnesium stearate, as a lubricant and anti-sticking agent, is commonly used by manufacturers in the production of tablets. It can prevent the powder from sticking together when the manufacturer presses the capsules. It can also improve the appearance of the pills and enhance production efficiency.
In the production of cosmetics, magnesium stearate is widely used as a thickener, lubricant and anti-caking agent. You can find it in powder compacts, eye shadows, blushes and other products. It can enhance the texture of cosmetics. This can make the product softer, smoother and easier to apply. It can also improve the stability and overall feel of the product.
