Calcium carbonate is a white fine crystalline powder, tasteless and odorless. There are two forms, amorphous and crystalline. Crystal type can be divided into rhombic and hexagonal crystal systems (anhydrous calcium carbonate is a colorless rhombic crystal, hexahedrons calcium carbonate is a colorless monoclinic crystal), is columnar or rhomboid, the density of 2.93g/cm3. The melting point is 1339 (decomposed at 825-896.6) and 1289 at 10.7MPa. Insoluble in alcohol, soluble in ammonium chloride solution, and almost insoluble in water. Recently, a customer in Kazakhstan, who operates a factory producing door and window profiles, purchased light calcium carbonate from us.

Iron Oxide Pigment Powder is a kind of pigment with good dispersibility, excellent light resistance, and weather resistance. They are opaque and strongly tinted artificial colors. Iron oxides are reliable colorants for all media, including crafts, plaster, cement, etc.
Iron Oxide Color Pigments mainly refers to iron oxide as the basic material of iron oxide red, iron yellow, iron black, and brown four kinds of pigments, which are given priority to iron oxide red (about 50% of the iron oxide pigments), micaceous iron oxide used as an antirust pigment, and used as a magnetic recording material of magnetic iron oxide also belongs to the category of iron oxide pigments.
Iron oxide is second only to titanium dioxide inorganic pigment, and is also the first color inorganic pigment. In the total consumption of iron oxide pigment, more than 70% is prepared by the chemical synthesis method, known as synthetic iron oxide.
Synthetic iron oxide due to its high synthetic purity, uniform particle size, and wide spectrum, color, inexpensive, and non-toxic, has excellent coloring and application performance, with UV absorption and other properties. They are made by synthesizing natural ingredients, are non-toxic, and responsibly produced.
Many iron oxide pigment quotes from factories focus on the availability of iron oxide pigment powder or powdered iron oxide for various industrial applications. These pigments, widely used in construction, coatings, and ceramics, are highly sought after for their durability and vibrant color. Manufacturers of iron oxide pigment provide different grades and colors, depending on the customer's needs.
Sericite is a kind of natural fine Muscovite.It is a layered structure of silicate.It can be split into very thin sheet, sheet thickness up to 1m (theoretically it can be cut into 0.001m), diameter to thickness ratio is large. The properties of it ar good wear resistance and wear resistance; heat resistant insulation; insoluble in acid-base solution; chemically stable. In addition, sericite is similar to kaolin in chemical composition and structure.It has some characteristics of clay minerals, such as good dispersion and suspension in aqueous media and organic solvents, fine white particles and viscosity.
Key Properties of Sericite Powder:
Smooth and soft texture: Sericite has a silky feel, making it ideal for cosmetic formulations.
Heat resistance: Its high thermal stability allows it to perform well in applications requiring heat resistance.
Good adhesion: It provides excellent adhesion when used in products like makeup or coatings.
Transparency and gloss: Sericite powder adds a subtle sheen and enhances the appearance of surfaces or skin.
Vermiculite is a kind of clay mineral similar to montmorillonite. It is a layered silicate. It is generally formed by hydrothermal alteration or weathering of biotite. It sometimes appears in the form of thick biotite (which is the biotite illusion of vermiculite), and sometimes in the form of soil. When vermiculite is heated to 300â??, it expands 20 times and bends. Vermiculite is a bit like a leech, hence its name. Vermiculite is generally brown, yellow, dark green, with an oily sheen, turning gray when heated.
After roasting at high temperature, the volume of vermiculite slices can rapidly expand 6-20 times, and the specific gravity after expansion is 60-180kg/m3, which has strong thermal insulation performance.
Our customers in Taiwan, China, who specialize in wholesaling horticulture and refractory materials, recently acquired expanded vermiculite from our inventory.
Rubber particles are mainly processed through all kinds of scrap rubber, including scrap rubber, tourist sole, scrap material, cable skin, rubber scrap, car cushion belt, car tire and other scrap rubber raw materials.
There are two kinds of rubber partickes,black rubber particles and color rubber particles. And the color rubber particles are divided into green rubber particles, red rubber particles, blue rubber particles, white rubber particles, brown rubber particles, yellow rubber particles and other color rubber particles.
The black rubber particles are typically made from recycled car tires and are widely used in sports fields, playground surfaces, and construction materials due to their durability and shock-absorbent properties.
Colored rubber particles, on the other hand, come in a variety of hues, including green, red, blue, white, brown, and yellow. These colors are achieved through specialized dyeing processes, making them ideal for decorative and functional applications such as playgrounds, running tracks, and landscaping projects. The aesthetic appeal and versatility of colored rubber particles have led to increased demand in urban design and recreational areas.
Silica fume, also known as microsilica, is a byproduct of the production of silicon and ferrosilicon alloys. It is an ultrafine powder consisting of spherical particles, typically about 100 times smaller than the average cement particle. This fine powder is rich in silicon dioxide (SiO) and is highly reactive when mixed with cement, making it a valuable additive in construction materials.
Features of Silica fume:
1, With good insulation: due to the high purity, low impurity content, stable performance, excellent electrical insulation performance, silica fume makes the cured product has good insulation performance and arc resistance performance.
2. It can reduce the peak exothermic temperature of the curing reaction of epoxy resin, reduce the linear expansion coefficient and shrinkage rate of the cured substance.
3, Corrosion resistance: silicon powder is not easy to react with other substances, and most of the acid, alkali can not react chemically.Its particles evenly covered on the surface of the object, with strong corrosion resistance.
