täyttöainetta

Täyttöainetta is a Finnish term that translates to "filler" or "filling material" in English. It refers to a substance used to add volume, bulk, or weight to a product or material. The specific nature of täyttöainetta depends heavily on its application. In industrial contexts, it can be used to reduce the amount of more expensive primary materials in plastics, paints, adhesives, or construction materials like concrete and plaster. These fillers are often inert minerals or powders, such as calcium carbonate, talc, or silica, and can also impart desired physical properties like increased strength, stiffness, or improved processing characteristics.

In the food industry, täyttöainetta might refer to ingredients added to processed foods to increase their volume and reduce the proportion of more costly components like meat or fat. Examples could include starches, flours, or water. Regulatory bodies often oversee the use of such additives to ensure they are safe for consumption and that consumers are not misled about the product's composition.

The term can also extend to cosmetic or medical applications. For instance, in cosmetics, "täyttöainetta" might refer to ingredients that fill in fine lines or add volume to skin. In a medical context, it could relate to substances used to fill voids or augment tissues, such as in dermal fillers. The common thread across all these uses is the addition of a substance to increase bulk or fill a space, often for economic or functional reasons.
