UV Stabiliser and Absorber Masterbatches
Extend the life time of polymers in outdoor use with the addition of UV stabiliser systems, protect packaged products from UV damage using UV absorber systems.
Protecting against damage from UV radiation.
Wells have created a range of UV stabilisers, to protect polymeric materials, and UV absorbers to protect packaged materials from UV light degradation. Wells UV stabiliser and absorber masterbatches can be custom formulated to suit specific applications or polymer types. Combination masterbatches containing both a stabiliser and an absorber are available.
How it works.
A common class of UV stabilisers are the hindered amine light stabiliser (HALS) systems. These work by interrupting the photo-degradation process before it can get destructively underway, thus protecting the polymer and extending the service life of the part. The mechanisms by which they achieve this used include “free radical scavenging” and “peroxide decomposition”.
Wells UV absorber masterbatches contain an active ingredient system which ‘absorbs’ UV radiation. Due to the presence of double bonds within its molecular structure, it is able to absorb light energy in the UV region and re-emit the energy in the IR region. This system prevents UV radiation from passing through the packaging material and reaching the contents inside.
Wells UV stabilisers are used in wide ranging areas including:
Blow moulding – Water butts, Tanks, Planters, Tubs
Injection Moulding – Garden furniture.
Film and profile – greenhouses, pallet covers, pipes
Fibres – nonwovens, artificial grass
Applications: Blown film, Cast Film, BOPP, Sheet Extrusion, Profile Extrusion, Blow Moulding, Injection Moulding, Nonwovens and Fibre
Polymer Carriers Available: PE, PP, PA, PET
UV absorbers are used in many packaging applications:
Packaging films – pallet covers, shrink films
Injection moulded (PP, PS and PET) pots, tubs and lids.
Blow moulded HDPE bottles, jars and drums.
Thermoformed , PP and PET trays
Applications: Blown film, Cast Film, BOPP, Sheet Extrusion, Profile Extrusion, Blow Moulding, Injection Moulding, Nonwovens and Fibre
Polymer Carriers Available: PE, PP, PA, PET’
