Polymer resins may contain a broad variety of additives in order to yield improved properties or to reduce the cost of the final product. Such additives may stabilize the polymer during high processing temperatures, reduce mechanical degradation as a result of prolonged exposure to UV light, or improve a material's flame-resistant properties.
As part of a material's selection or improvement process, Cambridge Polymer Group can work with your team to better understand your required material properties, manufacturing process constraints, and end-use environment. Strategies for bridging the gap between current and target performance specifications can include modifications to both the base polymer(s) in your system as well as to the additive packages.
Additionally, CPG can analyze existing polymer systems to characterize their additive package—both the identity of the additives as well as their relative concentration or weight fraction in the formulation. Such analysis may be performed on samples to identify evidence of additive degradation, heterogenous distribution, identify potential formulation changes, or for the purpose of resin equivalency studies.
CPG can assist in the characterization of polymer additives and additive packages including all commonly employed systems:
