The ageing of materials exposed to sunlight is a natural process. It is mainly caused by ultraviolet (UV) radiation.
Over time, sunlight can change a material’s appearance and properties. This may cause discolouration, loss of strength, cracking and surface degradation.
This issue mainly affects materials used outdoors, including plastics, paints, textiles, metals and wood. Therefore, accelerated ageing and UV weathering tests are used to assess their resistance to solar radiation.
These tests also help predict how materials will perform and how long they will last in real-world conditions.
Common applications of our UV ageing and solar simulation machines for analysing the resistance and durability of materials and products.
What types of deterioration can we recreate?
Sunlight contains ultraviolet (UV) radiation. This is primarily responsible for the deterioration of exposed materials.
UV radiation breaks down the molecules within materials. As a result, it affects their structure and can cause several forms of damage. These include discolouration, loss of elasticity, cracking and increased fragility.
To simulate the ageing of materials caused by sunlight, we have designed accelerated ageing chambers. In this way, the effects of prolonged solar exposure can be studied in a controlled environment.
These chambers reproduce extreme weather conditions, such as high temperatures and UV radiation. Therefore, they accelerate the ageing process and make it possible to evaluate the resistance of materials over time.
The study of material ageing under sunlight is important in many industries. For example, it is used in the automotive sector, construction and the manufacture of outdoor products. This type of testing helps predict the behaviour and durability of materials under real outdoor exposure conditions.
In addition, it is useful when developing new material formulations. These formulations can offer greater resistance to solar ageing and weathering. Furthermore, the tests support the study of material protection and conservation techniques.
