Sepiolite fiber is a kind of natural mineral fiber, which is a fibrous variety of sepiolite mineral, called α - sepiolite. Sepiolite is a kind of layered chain silicate mineral. In the structure of sepiolite, a layer of magnesia octahedron is sandwiched between two silicon oxygen tetrahedrons, forming a 2:1 type layered structure unit. The tetrahedral layer is continuous and the direction of active oxygen in the layer is reversed periodically. The octahedral layer forms a channel arranged alternately between the upper and lower layers. The channel orientation is consistent with the fiber axis, allowing water molecules, metal cations, organic small molecules and so on to enter. Sepiolite has good heat resistance. Sepiolite also has good ion exchange and catalytic properties, as well as corrosion resistance, radiation resistance, insulation, heat insulation and other excellent properties, especially the Si Oh in its structure can react directly with organics to generate organic mineral derivatives.
Sepiolite is also widely used in the fields of purification, superfine processing and modification. Sepiolite can be used as adsorbent, purifier, deodorant, reinforcing agent, suspending agent, thixotropic agent, filler, etc. in water treatment, catalysis, rubber, coating, chemical fertilizer, feed and other industries. In addition, sepiolite has good salt resistance and high temperature resistance, so it can be used as high-quality drilling mud material in oil drilling, geothermal drilling and other aspects.
Sepiolite fiber belongs to mineral fiber, which is obtained from fibrous mineral rock. Its main components are various oxides, such as silica, alumina, magnesium oxide, etc. its main sources are all kinds of asbestos, such as chrysotile, bluestone cotton, etc. mineral fiber includes aluminum silicate fiber, glass fiber, gypsum fiber, carbon fiber, etc.

1. Low resin dosage/high potential for addition: because in any shape, the spherical shape has the smallest specific surface area and the demand for resin for floating beads is also minimal. The accumulation of particles has also been improved. The wide particle size distribution of floating beads allows small microspheres to fill the gaps between larger microspheres. The result... is actually: high dosage, high solid content, lower VOC, and reduced dosage of other components;
2. Low viscosity/improved flowability: Unlike irregularly shaped particles, floating beads are easy to roll between each other. This results in lower viscosity and better flowability for systems using floating beads. Moreover, the sprayability of the system has also been improved;
3. Hardness/Wear Resistance: Drift beads are high-strength and hard microspheres that can enhance the hardness, washability, and wear resistance of coatings;
4. Excellent insulation effect: Due to the hollow spherical structure of floating beads, they have excellent insulation effect when filled in the coating;
5. Gloss control: As a filler, floating beads can reduce gloss and control surges. Even in situations with high requirements for addition, they can eliminate the significant increase in viscosity caused by ordinary matting agents, and the cost is also low;
6. Inertia: Drift beads are composed of inert components, thus possessing excellent durability, weather resistance, corrosion resistance, and chemical resistance;
7. Opacity: The hollow spherical shape of the floating bead slows down and scatters light, resulting in an increase in the covering power of the coating;
8. Dispersibility: Drift beads are dispersed like mineral fillers. Due to their thick walls and high compressive strength, they can withstand the processing of all types of mixers, extruders, and molding machines;
9. Non crystalline silicon pollution: Unlike other fillers, the content of crystalline silicon in floating beads is below a harmless level. This type of floating bead is not considered a carcinogen and does not require special hazard warning signs to indicate it.
10. High solid industrial coatings: low viscosity, high dosage, reduced VOC, improved hardness, controlled gloss, increased wear resistance, sprayability, and reduced cost;
11. Water soluble industrial topcoat: increase solid content, reduce film permeability, improve corrosion resistance, hardness, inertness, wear resistance, control gloss, and reduce costs;
12. Thermal insulation, insulation, and fireproof coatings: High temperature resistance, flame retardancy, and excellent insulation effect;
13 Maintenance Coatings: Chemical and corrosion resistance, durability, wear resistance, low coating permeability,
