Fillers are also called fillers and extenders. Some fillers are also body pigments. Micro-button fillers have good hiding power and are often used in the coating industry.

Fillers can be used in a variety of polyurethane products, such as polyurethane coatings, sealants: polyurethane slurries, special elastomers and polyurethane foams. Melamine plant fiber polymerization, saponin polyol, etc., organic fillers can be used in polyurethane foam; calcium carbonate kaolin (ceramic clay, porcelain clay), molecular sieve powder talc powder wollastonite titanium dioxide j barite powder (barium sulfate)', etc. Fine inorganic powders can generally be used as fillers for polyurethane sealants, polyurethane soft foam polyurethane elastomers, adhesives, polyurethane coatings, etc.

Generally refers to materials that are filled in other objects. In chemical engineering, packing refers to the inert solid materials installed in the packed tower, such as Pall rings and Raschig rings. Its function is to increase the gas-liquid contact surface and make them mix strongly with each other. In chemical products, fillers, also known as fillers, refer to solid materials used to improve processing performance, mechanical properties of products and/or reduce costs. Among them, fillers that can significantly improve the strength of products, such as long fibers and whiskers, are often called reinforcing materials, and carbon black is called reinforcing filler. Solid materials and calcium carbonate are often added as fillers in pharmaceutical tablets, cosmetics and detergents, but their purpose is to adjust dosage and concentration rather than improve performance, so they should be called diluents. Although plastic plasticizers, rubber oil extenders and spinning oils can improve performance and affect costs, these liquid materials are customarily regarded as processing aids.

In the polymer chemical industry, fillers (fillers) are the most commonly used additives. Almost all plastics (including thermoplastic and thermosetting plastics), natural rubber and coatings use a large amount of fillers. For example, adding wood powder, clay or calcium carbonate when manufacturing plastics can not only improve the mechanical properties of the product and increase the hardness, but also reduce costs; using graphite, magnetic powder or mica as fillers can improve the electrical conductivity, magnetic flux and resistance of the plastic. Thermal properties; adding carbon black or silica (white carbon black) to rubber can significantly improve the physical properties of the product; adding titanium dioxide (titanium dioxide) to the spinning solution can shading and dyeing. In the coating industry, white or colored fillers (such as titanium dioxide, talc, calcium carbonate, barium sulfate, etc.) are often added to improve the optical, physical and chemical properties of the coating. Fillers (fillers) for this type of use are called extender pigments or Exhibit color material.
