Stabilizers weathering

Silicone rubber tubes are mainly utilized in medical and food technology e.g. as transfusion tubes, catheters and tubes for drinks. Silicone cables are widely utilized in applications for which thermal stability, weathering resistance and chemical resistance are required e.g. baking ovens, hot lamps and electrical connections for electrical motors and transformers. 

Any plastic constituent in addition to the function it serves must have heat stability, UV light stability, weather resistance, low solubility in terms of extraction, compatibility with other constituents and good dispensability. Where plastics have to be sterilised by irradiation, certain constituents may be degraded, or even continue to degrade after irradiation. Certain antioxidants are degraded by gamma irradiation.

Outstanding properties such as thermal stability, weathering resistance, low temperature flexibility, low surface tension, hydropho-bicity and surface activity of silicone resins and their combinations with other resins made them a commercially important category of binders for high performance coatings. 

Despite their dull color, red iron oxide pigments find applications in different architectural and industrial coatings due to their excellent thermal stability, weather fastness, solvent resistance, chemical resistance, cost effectiveness and high hiding power.

The use of fluorinated structures in polymeric networks is veiy attractive due to their peculiar characteristics, connected to the presence of fluorine, such as chemical and thermal stability, weathering resistance, low surface tension, hydrophobicity and oleophobicity, optical and electrical behaviour [32]. It seemed interesting to employ fluorinated structures in UV-curable systems in order to combine the properties of these molecules and the advantages of the UV-curing technology, giving rise to eured products with outstanding properties.
