*Profile.*
The UV Accelerated weathering test chamber simulates damage caused by solar ultraviolet light, and the material is subjected to weather resistance test by exposing the sample to light under controlled high temperature. It uses ultraviolet light tubes to simulate the effects of sunlight. In just a few days or weeks, the chamber can reproduce damage that can take months or even years outside, including fading, color changes, tarnishing, chalking, cracking, cracking, wrinkling, blistering, embrittlement, strength reduction, oxidation, etc., can be used to select new materials, improve existing materials, or evaluate changes in material formulations. 4 pieces together (UVA-340 and UVB-313 optional).
