Microlab deploys the State-of-Art Accelerated Weathering Equipments
Sort by Properties
Xenon weathering test chambers use Xenon-arc lamps that produce light wavelength range that covers UV, Visible Light and IR. This exactly simulates the exposure to direct sunlight or filters of window glass sunlight as well as rain or dew. Product degradation study can be done at various controlled conditions of varying Irradiance, Temperature and Humidity. This helps to optimize the composition and quality of the product. Xenon cabinet and Bench Xenon are used for these testing.

ASTM D 2565: Xenon-Arc Exposure of Plastics Intended for Outdoor Applications.
UV Weathering Test
UV weathering is an accelerated ageing exposure of plastics to sunlight. The polymer degradation and lifetime can be predicted by accelerating the exposure at different duration, temperature and humidity.
Also it is possible to simulate the natural conditions of sunlight and rain on the same day which creates thermal shock on the materials. This helps to imagine the behavior of the material under various natural conditions.
UV Weathering chamber and Bench UV are used for these testing.
Temperature-Humidity Cyclic Ageing
Accelerated degradation of plastics is caused by combined action of temperature and humidity. The severity of these two factors will depend on the geographic location and need to be taken into account when designing the materials.
The conditions of temperature, humidity and time can be varied and run on a cyclic ageing to simulate the actual climatic condition at which the material will be used.
The temperature can be cycled from -60 degC to 150 degC, with a humidity control from 20% RH to 98% RH.
