Sunlight is a major cause of damage to a number of materials, including plastics, textiles, coatings, and other organic materials. The type of damage, such as loss of physical properties, chalking, cracking, peeling, fading, and color change. For durable materials, like most coatings and plastics, short-wave UV is the primary cause of polymer degradation. However, for less durable materials, like many dyes and pigments, longer wave UV, and even short-wave visible light, can cause significant damage.
For many manufacturers, it is crucial to understand the effects of prolong sunlight exposure to your products.
Accelerated weathering testers are designed to simulate natural sunlight, and are widely used for research and development, quality control and material certification. These testers can provide fast, repeatable and reproducible results. The QUV Accelerated Weathering Tester and the xenon arc are the most commonly used accelerated weathering and light stability testers. These testers are based on two completely different approaches.
Xenon arc testers, such as the Q-SUN® Xenon Test Chamber, reproduce the entire spectrum of sunlight including ultraviolet (UV), visible light and infrared (IR). The xenon is essentially an attempt to reproduce sunlight itself. While on the other hand, QUV testers do not attempt to reproduce the full spectrum of sunlight, but, rather, just the damaging effects of sunlight.

In this case study, learn about how outdoor exposure and climate changes causes polymer degradation through the extensive weathering test results and graphs of an actual test done for architectural application.
Starting a new lab is an exciting venture, full of promise, creativity, and new discoveries. It’s also not the easiest thing to accomplish. Considerable deliberation goes into starting a lab, including mountains of paperwork and countless decisions that you need to make. Here are some factors to consider when starting a laboratory that can help it become more productive, efficient, and above all, successful.
Due to its significant impact on consumer preferences for food items, ensuring exact consistency in color is crucial. The color of food is closely linked to the biological, chemical, and
