UVállóság

UVállóság refers to the ability of a material to withstand the damaging effects of ultraviolet (UV) radiation. UV radiation, a component of sunlight, can cause degradation in many substances, leading to changes in their physical and chemical properties. This degradation can manifest as discoloration, loss of strength, embrittlement, cracking, or chalking.

Materials with good UVállóság are essential for products intended for outdoor use or exposure to UV light sources. This includes items like paints, plastics, textiles, coatings, and outdoor furniture. Manufacturers often incorporate UV stabilizers or absorbers into their products to enhance their resistance to UV damage, thereby extending their lifespan and preserving their aesthetic and functional qualities.

The degree of UVállóság is typically determined through standardized testing methods that expose materials to accelerated UV radiation and measure the extent of any resulting degradation. This allows for the comparison of different materials and the selection of those best suited for specific applications where UV exposure is a concern. Understanding and improving UVállóság is crucial for ensuring the durability and performance of a wide range of manufactured goods.
