Barium sulfate is superior to most other filling powders and has characteristics such as low cohesion, low light dispersibility, and fine particles. Barium sulfate is particularly suitable for pigment topcoats, varnishes, spray paints, etc. It has chemical resistance and weather resistance. It is inert, insoluble in organic mediators such as water, acid, and alkali, and its excellent glossiness and particle fineness enable the topcoat to be maintained during long-term exposure. Barium sulfate is recommended for topcoats to increase surface hardness and color stability.

Sericite powder has fine and smooth feeling, stable chemical performance, strong adhesion, good dispersion, uniform mixing with water and glycerin, silky luster, UV resistance and other excellent characteristics, and is a high-quality raw material for various cosmetics in the beauty cosmetics industry. Due to its delicate texture, elasticity, suitable glossiness, high whiteness, and minimal or no heavy l elements such as lead and mercury, it can meet the special requirements of some high-end beauty cosmetics.
Sericite, with its unique fine scale structure and silk luster, can significantly improve the optical properties of plastic products, improve the air tightness, rigidity, heat resistance and dimensional stability of plastic products when it is used as a reinforcing filler in the plastic industry, which is also the difference between sericite and other inorganic fillers.
In the rubber industry, sericite is a good filler or extender, which can reduce the rubber content of materials and thus reduce production costs. Sericite has a unique sheet structure, which can effectively improve the damping performance of rubber. Its good compression resistance, tensile resistance, light resistance, fire resistance, weather resistance, heat resistance, acid resistance and electrical insulation physical and chemical properties can improve the mechanical properties, heat resistance, aging resistance and other functions of rubber products with sericite added, and can be used in the development of special rubber products.
1.National Bureau of Statistics: From January to March, the national real estate development investment of 2597.4 billion yuan, decreased by 5.8 percent year-on-year; among them, residential investment of 197.67 billion yuan, decreased by 4.1 percent. 2.National Bureau of Statistics: CPI rose moderately, while the price for industrial producers fell year-on-year 3.National Bureau of Statistics: National industrial capacity utilization rate was 74.3 percent in Q1 4. National Bureau of Statistics: Promoting a higher level of dynamic balance between supply and demand, and improving the healthy development of industry
Ultra fine sericite powder is a new type of functional filler, which is widely used in the field of paints and coatings. Because sericite powder is in the form of fine flakes, smooth crystal surface, large diameter thickness ratio, high whiteness, stable chemical performance, light weight, smooth, insulation, and radiation resistance, it is a good filler for various high-grade paints, rust prevention, fire prevention, and anti-corrosion coatings. Due to the ed structure of sericite, the dye particles enter the lattice of sericite, which can keep the paint film from fading for a long time.
Polypropylene fiber woven bags have widely replaced jute woven sacks and become the most important basic packaging materials for grains, industrial raw materials, fertilizers, food, mineral sand, and coal. Their forms have long evolved from traditional pillow ladder style to barrel and column style. Due to its low density, light weight, conformability, and easy storage, it has even replaced some small containers.
Polypropylene is a non-toxic, odorless, and tasteless milky white high crystalline polymer that is not toxic. Polypropylene is non-toxic, odorless, with low density, and superior strength, stiffness, hardness, and heat resistance to low-pressure polyethylene. It can be used at around 100 ℃. It has good dielectric properties and high-frequency insulation, and is not affected by humidity, but becomes brittle at low temperatures, is not wear-resistant, and is prone to aging.
Color masterbatch, also known as color variety, is a new type of polymer material specific colorant, also known as pigment preparation. Color masterbatch is composed of three basic elements: pigment or dye, carrier, and additive. It is an aggregate obtained by uniformly attaching a super constant pigment or dye to a resin, and can be called a pigment concentrate. Therefore, the coloring power of color masterbatch is higher than that of the pigment itself.
Polypropylene plastic (PP) is another excellent resin variety developed after nylon. It is a high-density, side chain free, high crystalline polymer with excellent comprehensive properties. When not colored, it appears white, translucent, waxy, and lighter than polyethylene. The transparency is also better than polyethylene, and it is harder than polyethylene. characteristics of Polypropylene plastic (PP) are high heat resistance, toughness, shock resistance, and good acid and alkali resistance. At room temperature, Polypropylene plastic (PP) is insoluble in organic solvents and will not dissolve even after long-term immersion in organic solvents.
Is polypropylene (PP) a food grade material?Not all polypropylene in polypropylene is food grade, and the polypropylene material involved in the food industry is food grade.
Polypropylene (PP) is a semi crystalline thermoplastic. Polypropylene has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid alkali corrosion. Polypropylene has a wide range of applications in the industry and is one of the commonly used polymer materials. Australian coins are also made of polypropylene.
When purchasing PVC boards, you should carefully observe the surface of the board to ensure flatness and no color difference. If there are slight cracks or scratches found on the PVC board, even if the merchant explains and offers discounts, they cannot purchase to avoid buying counterfeit products.
