boron nitride for cosmetics

Boron Nitride For Cosmetics is widely used as an additive in make-up cosmetics, which is moist and has a good pearlescent effect. Boron Nitride For Cosmetics has the advantages of non-abrasion, low wear, dimensional safety, good lubricity, fire resistance and easy processing. The coefficient of friction of Boron Nitride For Cosmetics is as low as 0.16. The friction coefficient of Boron Nitride For Cosmetics does not increase at high temperature, and boron nitride has higher temperature resistance than molybdenum disulfide and graphite. Boron Nitride For Cosmetics can be used up to 900℃ in oxidizing atmosphere and 2000℃ in vacuum. Boron Nitride For Cosmetics has poor lubricating properties at room temperature, so it is often mixed with graphite fluoride, graphite and molybdenum disulfide as a high-temperature lubricant. The Boron Nitride For Cosmetics is divided into two specifications according to different grades, BNR-01 and BNR-02.The chemical composition of the product should meet the requirements in the following table (mass fraction).

Boron Nitride products are synthesized from boric acid and melamine at high temperature. Boron Nitride has the advantages of less impurities, high purity, good crystallinity, and adjustable particle size. For different industries, Boron Nitride is mainly divided into: boron nitride for ceramics, Boron Nitride for thermal conductivity, Boron Nitride for cosmetics and Boron Nitride for lubrication. Boron Nitride is used as polymer additives such as functional plastics, epoxy resins, silica gels, polyimides, polyurethanes, nylons, etc. The main function of Boron Nitride is to enhance thermal conductivity, insulation, friction resistance, corrosion resistance, and reduce dielectric constant and dielectric loss. The Boron Nitride is divided into two specifications according to different grades, BNR-01 and BNR-02.The chemical composition of the product should meet the requirements in the following table (mass fraction).
