Polymer Chemical Testing

Polymer chemical testing or chemical analysis of polymers is used to identify fundamental polymer chemical structural information such as functional groups, molecular weight, molecular weight distribution and information on branching. Where formulated polymer products are in development, plastics chemical composition testing is required to ensure that a material is suitable for its intended application.

The composition of plastics can be complex. Chemical analysis of plastics can provide valuable information on the additives used and other substances present, which is important when trying to understand material performance. Additives, in particular, can impact the polymer physical properties, stability/stabilization and general durability over the lifecycle of the polymer material. Other substances present include catalyst residues and volatile organic contaminants (VOCs).

Our polymer chemistry scientists apply the most appropriate chemical tests to get the data you need to understand your product’s quality and performance. With expertise in polymer formulation support, our experts can support your product development, competitor polymer material deformulation, comparative composition analysis of blends and regulatory submission data requirements. We can also provide advanced analysis for additives and fillers present. Quality control of polymer raw materials and finished, formulated, products can be achieved through a wide range of chemical tests and techniques.

Polymer Chemistry Expertise
Supporting the entire polymer lifecycle, our teams provide polymer chemical analysis to drive insight about your polymer product or raw materials using a range of polymer characterization techniques such as molecular weight (MW) of polymers, chemical structure of polymers, chemistry of fractions, end group analysis of polymer, tacticity, unreacted monomer and oligomers, co-polymer content and blend composition, catalyst residues, plastic chemical structure, contamination analysis, chemical trace analysis and plastics and polymers volatile organic compounds testing.

Polymer Chemical Analysis Technology
Our polymer analysis laboratories utilise a wide range of techniques including spectroscopy, microscopy and chromatography, with a combined knowledge base which includes method development and validation, and with industry standard test methods to ensure a material meets compliance requirements. We possess a wealth of troubleshooting experience and considerable failure analysis insight, as part of our broad polymer and plastic identification testing expertise. Our experts bring you insight into your material’s chemical composition and 'fingerprint', helping you to understand degradation and performance over the products lifetime: invaluable for ensuring that the material is the optimum choice.
