Töltelékanyagokat

Töltelékanyagokat, commonly referred to as fillers, are substances added to other materials to reduce the cost, improve workability, or enhance certain properties of the final product. They are widely used across various industries, including plastics, rubber, paints, coatings, adhesives, and even food products. The choice of filler depends heavily on the base material and the desired outcome.

In the plastics and rubber industries, fillers are often mineral-based, such as calcium carbonate, talc, or kaolin clay. These inorganic fillers can increase stiffness, improve tensile strength, reduce shrinkage, and lower the overall cost by replacing more expensive base polymers. For example, calcium carbonate is a common filler in PVC pipes and profiles, while carbon black is a crucial filler in rubber tires, providing reinforcement and abrasion resistance.

In paints and coatings, fillers like silica, barytes, and mica are used to control gloss, improve opacity, enhance rheological properties, and reduce the amount of expensive binders and pigments. They can also contribute to the durability and weather resistance of the coating.

In food applications, fillers are used to add bulk, improve texture, or act as carriers for other ingredients. Examples include starch in processed meats or cellulose in low-calorie products. The use of fillers in food is strictly regulated to ensure safety and prevent misrepresentation of the product's composition. The term "töltelékanyagok" in this context refers to any material added to increase volume or reduce the concentration of primary ingredients.
