Ultraviolet light flame retardancy

There is the possibiUty of a chemical reaction between a plastic and a colorant at processing temperatures. Thermal stabiUty of both the polymer and colorant plays an important role. Furthermore, the performance additives that may have been added to the resin such as antioxidants, stabilizers, flame retardants, ultraviolet light absorbers, and fillers must be considered. The suitabiUty of a colorant in a particular resin must be evaluated and tested in the final apphcation after all processing steps to ensure optimum performance. 

In recent years, a new and emerging class of clay-filled polymers called Polymer-Clay Nanocomposites (PCN) was developed. Properties such as superior mechanical strength, reduction in weight, increased heat-resistance and flame retardancy, improved barrier properties against oxygen, carbon dioxide, ultraviolet light, moisture and volatiles, as well as conservation of flavor in drinks and beverages are achievable with these novel composites [17-21].
