UV Stabilizer Masterbatch

Why Use UV/Light Stabilizer Masterbatches?

Exposure to sunlight and some artificial lights can have adverse effects on the useful life of plastic products. UV radiation can break down the chemical bonds in a polymer. This process is called photodegradation. It ultimately causes cracking, chalking, colour changes and the loss of physical properties. To counteract the damaging effect of UV light, UV stabilizers are used to solve the degradation problems associated with exposure to sunlight.

UV stabilizers can be categorized by two general classifications - ultraviolet light absorber (UVA) and hindered amine light stabilizers (HALS). HALS are extremely efficient stabilizers against light- induced degradation of most polymers. They do not absorb UV radiation, but act to inhibit degradation of the polymer. Significant levels of stabilization are achieved at relatively low concentrations. HALS high efficiency and longevity are due to a cyclic process wherein the HALS are regenerated rather than consumed during the stabilization process. UV light is normally defined as being within the region of 280-400nm, while visible light is found within 400-800nm. UV light is then subdivided further into UV-A (the lower wavelengths, peaking around 310nm) and UV-B (slightly higher wavelengths peaking at around 350nm). Sunlight intensity and composition varies according to latitude, atmospheric effects etc. so it is important that the additive (or more normally the combination of additives) is selected to suit the exact application. It is therefore important to identify where in the world a final product will be used and the required life span. Other factors that affect the choice of UV stabilisation package include product dimensions, type and colour of pigments present and application information such as food or pesticide contact.

The addition level of AddKan UV Stabilizer Masterbatches depends on the thickness of article, intensity of Sun/UV light, period of exposure and life expectancy required in these conditions.

AddKan UV Stabilizer Masterbatches are available for specialised applications like green house films. They have UV stabilizers which are resistant to pesticides. Depending upon customer needs we can supply UV stabilized Colour Masterbatches also.
