Stabilizer compositions having a stabilizing amount of at least one co-active agent; an ultraviolet light absorber chosen from an ortho-hydroxy benzophenone, and/or an ortho-hydroxyphenyl benzotriazole; and a hindered amine light stabilizer, are provided herein, along with masterbatch concentrates containing same, and processes for using same for stabilizing polymeric organic materials to protect against light and thermal degradation due to exposure to UV irradiation.

Stabilizer compositions and methods for using same for protecting polymeric organic materials from UV light and thermal degradation

Stabilized compositions having an organic material to be stabilized and a resin masterbatch system provided as closed end pellets are provided herein, along with processes for producing stabilized articles.

Stabilized compositions and process for producing same

Resin masterbatch compositions are provided as closed end pellets having a core including at least one additive and an outer layer comprising a polymer encapsulating the core, in which the thickness of the outer layer if from 0.001 mm to 1 cm. A stabilized composition is prepared from an organic material to be stabilized and the resin masterbatch composition. A process for producing the resin masterbatch composition includes co-extruding in tubular form a core material encapsulated by an outer layer, wherein the core material comprises at least one additive, and the outer layer comprises a polymer, to form a filled tube; passing the filled tube into a sealing device that cuts the filled tube into multiple discrete segments seals and simultaneously seals each end of each discrete segment, thereby forming closed end pellets; and cooling the closed end pellets.

Encapsulated stabilizer compositions

A process for producing a stabilized molded article including: combining a stabilizing amount of a thermal and ultraviolet (UV) light stabilizer composition with an organic material subject to degradation induced by light, heat or oxidation to form a stabilized organic material; and forming the stabilized organic material into a molded article, wherein the stabilizer composition comprises an ortho-hydroxyl tris-aryl-s-triazine compound; a hindered amine light stabilizer compound; a hindered hydroxybenzoate compound; an acid scavenger; a phosphite compound; a hindered phenol antioxidant compound; and a thioester compound.

Processes for producing molded articles stabilized against ultraviolet light and thermal degradation

Stabilizer compositions for stabilizing materials against degradation due to thermal and ultraviolet light exposure are disclosed herein. In some instances, the stabilizer compositions include an ortho-hydroxyl tris-aryl-s-triazine compound; a hindered amine light stabilizer compound; a hindered hydroxybenzoate compound; a phosphite compound, an acid scavenger and/or thioester; and a hindered phenol antioxidant compound.
