Photoaging testing is the process of simulating the aging of a product under various factors (light, water, heat) involved in real-world usage conditions, and conducting corresponding condition enhancement experiments. At the same time, based on usage requirements, it reasonably predicts the product's service life.

Material aging includes fading, loss of gloss, decreased strength, cracking, peeling, powdering, and oxidation.

The aging experiment mainly targets polymer materials (plastics, coatings, adhesives, and rubber). Common aging methods include artificial natural climate aging, ultraviolet aging, light aging, humid heat aging, and thermal oxidative aging.

Product scope

Can conduct photo aging tests on electronic, instrumentation, automotive interior and exterior components, as well as components, structural parts, assemblies, and complete machines for aerospace products
