Sunlight together with heat and oxygen induces degradation in plastic products, causing detrimental effects on their mechanical, optical and physical properties. The result is breakage, chalking and discoloration. Outdoor weathering too adds up to degradation by exposure to the UV rays that reach the earth’s surface, at wavelengths between 300 and 400 nanometres. Environmental factors like temperature, humidity, oxygen, polluting gases also play an important role.
It gradually corrodes the plastic by making it brittle, dull and faded. Lifeline has innovated UV Stabilizer Additive Masterbatches to overcome this problem and prolong the life and utility of plastic products.
UV Stabilizer Additive Masterbatches protect the polymer from degradation. The protection mechanism may work in different ways as follows
