Polymer Analysis and Testing Services

Often yes. FTIR/Raman is typically the first step; more complex blends or additives may require Py-GC/MS, GC-MS, or NMR for confident identification.

We can often screen and compare additive signatures. Absolute quantification may require standards and a targeted method plan.

Yes. Depending on the resin system and project objective, resin deformulation and reverse engineering may combine spectroscopy, chromatography, mass spectrometry, thermal analysis, molecular weight analysis, microscopy, and elemental analysis to identify resin chemistry, additives, fillers, curing-related components, and important formulation differences. Exact reconstruction depends on sample complexity, component concentration, and the availability of suitable analytical methods and reference standards.

Yes. Cured coatings and adhesives may require a combination of spectroscopy, pyrolysis, extraction, chromatography and microscopy to identify binder chemistry, additives, fillers, contaminants and failure-related differences.

Yes. Polymer analysis can help investigate cracking, brittleness, discoloration, odor, surface blooming, contamination, aging failure, and abnormal material performance.

Sample requirements depend on the product type, formulation complexity and analytical methods required.

As a general guideline, about 100mL for liquid samples or about 10g for solid samples is often sufficient for many projects.

For complex, limited or unusual samples, please contact Xinbodi’s engineers before shipment so we can confirm the recommended sample quantity.

Crystallinity can affect strength, flexibility, transparency, shrinkage, heat resistance, chemical resistance, and failure behavior. DSC and XRD are commonly used to support crystallinity evaluation.

Polymer identification mainly answers “What is the base polymer or resin?” Polymer composition analysis goes further by investigating additives, fillers, plasticizers, stabilizers, pigments, contaminants, and other components that may affect material performance.

Yes, but cured and crosslinked materials usually require a multi-technique approach because they may not dissolve or separate like uncured resins. FTIR, Py-GC/MS, thermal analysis, extraction, microscopy, and other methods may be combined depending on the material and analytical objective.

FTIR may confirm that two samples belong to the same polymer family, but their molecular weight, crystallinity, filler loading, plasticizer level, antioxidant package, reinforcement, contamination, or processing history may still differ. Additional techniques such as GPC, DSC, TGA, GC-MS, LC-MS, XRF, or SEM-EDS may be needed to explain the performance difference.

A polymer testing lab may evaluate material identity, chemical composition, additives, molecular weight, thermal behavior, fillers, contaminants and selected physical or mechanical properties. The test plan depends on whether the goal is material verification, supplier comparison, failure investigation or product development.

Polymer composition analysis identifies the base polymer and investigates additional components such as plasticizers, stabilizers, flame retardants, pigments, fillers, processing aids and contaminants. More complex formulations may require several complementary techniques.

A polymer analysis laboratory is useful when you need to identify an unknown material, verify a supplier, compare two grades or batches, investigate a failure, identify contamination, or understand the formulation of a competitor or replacement material.
