HIGHLIGHTS

Exposure to sunlight and some artificial lights can have adverse effects on the useful life of polyolefin products. UV radiation can break down the chemical bonds in a polymer. This process is called photo-degradation which causes cracking, chalking, color changes and loss of such physical properties as impact strength, tensile strength, elongation and others.; UV Stabilizer Masterbatches are used to prevent the formation of free radicals, thus protecting the polymer chain from breaking. As a result, mechanical properties of the polymers are retained even after exposure to sunlight (outdoor application).; UV light is normally defined as wavelength of light within the region of 280-400nm, while visible light is within 400-800nm. UV light is then subdivided further into UV-A (the lower wavelengths, region around 310nm) and UV-B (slightly higher wavelengths region at around 350nm).; Sunlight intensity and composition varies according to latitude, atmospheric effects like humidity etc. So, it is important that the additive (or usually a combination of additives) is selected to suit the exact application, also taking into account the location that the final product will be used in and the required life span. Other factors that affect the choice of UV stabilization package include product dimensions, type and color of pigments present and application-specifics such as food or pesticide contact.
