Stabilization systems for polymeric materials in pellet form |
abstract |
A stabilizing system for stabilizing polymeric materials against ultraviolet light and thermooxidative deterioration is provided in which the stabilizing system is in pellet form. The pellet is formed from a substantially dry homogeneous mixture of at least one stabilizer and an agent which will prevent melting of the stabilizer. The stabilizer compound makes up about 50 % to about 98 % by weight of the mixture. The stabilizers are antioxidants (such as phosphites and hindered phenols) or hindered amine UV light stabilizers, or combinations thereof. The melt preventing agent may be a compound derived from a fatty acid or a fatty alcohol, or a fatty acid or a fatty alcohol, or a combination of fatty acids or fatty alcohols which makes up about 3 % - 10 % of the homogeneous mixture. The fatty acids, fatty alcohols, and the compounds derived therefrom preferably have a low melting point in the range of 50-100 °C and preferably between 50 °C and about 80 °C. The melt preventing agent may alternatively be a lubricating agent having a small particle size (e.g., less than 100ν) which makes up about 2-50 % by weight of the homogeneous mixture. |
