Täyteainehiukkaset, often translated as filler particles or simply fillers, are inert substances added to materials to impart specific properties or reduce costs. They are commonly used in polymers, plastics, paints, coatings, adhesives, and construction materials. The primary functions of filler particles include increasing mechanical strength, improving stiffness, enhancing dimensional stability, reducing shrinkage, and sometimes providing electrical or thermal conductivity. In many applications, fillers are also used to reduce the amount of more expensive base material, thereby lowering the overall cost of the product.

The choice of filler particle depends on the intended application and the desired properties. Common examples include calcium carbonate, talc, kaolin, silica, glass fibers, and carbon black. The particle size, shape, and surface chemistry of the filler can significantly influence its dispersion within the matrix material and its effectiveness in achieving the desired performance characteristics. Surface treatments are often applied to filler particles to improve their compatibility and adhesion with the host material, which is crucial for optimal property enhancement.

The use of filler particles is widespread in various industries. In the automotive sector, they are used in plastics for interior and exterior components to improve durability and reduce weight. In construction, fillers are incorporated into concrete and sealants to enhance strength and reduce cracking. In the electronics industry, conductive fillers like carbon black or metal particles are used to create antistatic materials or thermal management solutions. The development of new filler materials and surface modification techniques continues to expand the possibilities for improving material performance and creating innovative products.
