The composition of rubber 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 polymer type identification, researchers can compare performance criteria before specifying a material for use.
Some common techniques used determine the polymer type present in a compound include:
Other common methods are noted in ASTM D3677. Smithers experts can recommend the optimal testing technique based on the investigation that is required.
