Abstract: A colorized and tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer in combination with at least one tribological modifier. The tribological modifier may include a fluoropolymer. The polymer composition further contains at least one coloring agent in combination with a color stabilizer. The color stabilizer has been found to dramatically improve color consistency. Polymer articles molded from the polymer composition not only have excellent surface appearance but have excellent low friction characteristics when tested against aluminum.

Abstract: Organopolysulfides such as organodisulfides, organotrisulfides and/or organotetrasulfides are useful stabilizers for polymer compositions, wherein the tendency of a polymer to degrade when exposed to environmental conditions such as heat, light and oxygen may be ameliorated by the incorporation of one or more of such organopolysulfides, optionally together with one or more additional stabilization additives such as a hindered phenol antioxidant, phosp(on)ite stabilizer or hindered amine light stabilizer.

Abstract: The present disclosure relates to reaction products formed from a thermoplastic vulcanizate compositions, articles made therefrom, and methods for making such reaction products. The reaction products may include a thermoplastic vulcanizate, a functionalized polymer, and an inorganic filler. Such reaction products may advantageously exhibit reduced coefficient of linear thermal expansion as compared to a product that is otherwise identical, but which do not contain the functionalized polymer and/or inorganic filler. The reaction product may be used in automotive extruded sealing profiles, such as glass run channel, glass encapsulation, and belt line seals.
