Stabilization systems for polymeric material in pellet form

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