Contact AmandaThe composition of rubber and plastics in cured, compounded products can give researchers a view at the predicted life of the material. While certain polymers may have superior elasticity, for example, they may have inadequate ozone resistance in a given application. Through the identification of polymer types and blends, our team can compare performance criteria before specifying a material for use.
Some common techniques used determine the polymer type and polymer blends present in a compound include:
Other common methods are noted in ASTM D3677.
Smithers experts can recommend the optimal testing technique for identifying polymer blends and polymer types based on the investigation that is required.
