Täiteaineteks

Täiteaineteks, often translated as "fillers" in English, refers to substances added to materials to modify their properties, reduce costs, or improve processing. These substances are typically less expensive than the primary material and are incorporated in significant quantities. The specific type of filler used depends heavily on the base material and the desired outcome.

In the plastics industry, common fillers include calcium carbonate, talc, and glass fibers. Calcium carbonate is frequently used to increase stiffness and reduce the cost of polymers like PVC and polypropylene. Talc, a mineral, can enhance heat resistance and dimensional stability in plastics. Glass fibers are added to plastics to significantly improve strength and impact resistance, creating composite materials.

In the construction sector, fillers are used in products like concrete, mortar, and paints. Sand and gravel are classic examples of aggregate fillers in concrete, providing bulk and strength. In paints, extenders like barytes and kaolin are used to increase opacity, improve flow properties, and reduce the amount of more expensive pigments.

The use of täiteaineteks is a widespread practice across various manufacturing disciplines. Careful selection and precise control over the amount of filler are crucial to achieve the intended performance characteristics without negatively impacting the material's overall integrity or functionality. Understanding the interaction between the filler and the base material is key to successful application.
