UV Stabilisers & Absorbers for Blown film

Plastics materials can be susceptible to damage by the action of UV radiation. Sunlight is a powerful source of UV radiation and products such as garden furniture, heating oil tanks, and greenhouse films which are required to spend extended periods outdoors as part of their service life will need protecting against this harmful degradation.

The use of UV stabiliser systems allows parts for prolonged outdoor use, and in different climates with differing levels of UV light exposure, to be designed with a high level of confidence that they adequately fulfil their service life and performance requirements.

Another feature of UV radiation is that it is not only potentially damaging to the polymer but also in packaging applications, to the contents of the packaging. UV radiation not only come from the sun, but can also come from artificial sources, like fluorescent lighting in supermarkets. This could potentially cause undesirable changes to packaged goods e.g. colour change, and odour and flavour loss in foodstuffs. Adding a UV absorber will help protect the pack contents from damage by UV light.
