How does this differ from complete deformulation?

Characterization describes selected chemical features useful for a decision. Deformulation places more emphasis on identifying formulation components and estimating their proportions. We agree the scope that matches the question you submit.

Can you help compare replacement raw materials?

Yes. A side-by-side chemical comparison can highlight similarities and differences. Application trials remain necessary where processing or performance requirements go beyond the chemical findings in the report.

Will all listed methods be used?

No. The methods depend on the material and analytical question. The quotation defines the scope, and the data appendix identifies the methods actually used and relevant limitations.

Can I combine identification and a batch comparison?

Yes. Explain both questions and supply clearly labelled specimens. We can propose a defined scope connecting material-family evidence, suitable component findings and the differences between the submitted samples.

Materials characterization through chemical and composition evidence

Which chemical features define a material well enough to compare it with another? Materials characterization brings together composition evidence, material-family assignments and selected wet-chemistry measurements. Chengfenbao helps product developers and purchasing teams describe a reference material and investigate chemical differences in candidate replacements. We define the analytical question around your decision. The service focuses on the listed chemical methods; matching their results does not establish that two materials will behave identically under every processing or application condition.

Discuss your sample

What we analyze

We characterize coatings and paints, inks, adhesives and sealants, rubber and elastomers, plastics and masterbatch, additives and raw materials, cleaners, lubricating greases, concrete admixtures, and cosmetics and personal care products. We confirm the actual sample form and receiving arrangements before shipment, including whether you are comparing liquids, solids or cured specimens.

A characterization project might describe a base-polymer family, accessible additive system, inorganic contribution and moisture or solids content. For substitution work, provide the current material and candidate references with clear identities. Explain the processing problem or purchasing requirement so the analytical scope focuses on useful comparison points.

How we work

FTIR supports binder and polymer-family comparison. GC-MS and GC-MS/MS address suitable volatile and accessible organic components. High-resolution LC-MS and LC-MS/MS help investigate suitable additives. Analysts explain when a reacted matrix, overlapping components or low available quantity limits the level of detail.

XRF, XRD, ICP-MS and ICP-OES provide complementary information about inorganic ingredients and elements. Wet chemistry may include solids content, moisture, pH and UV-Vis when relevant. The report connects each result to the agreed question and distinguishes a direct measurement from an interpretation about the original formulation or likely material family.

What you receive

The conclusion card answers the agreed question in plain language and relates the findings to the submitted sample. We distinguish analytical evidence from background information supplied with the inquiry.

The component table lists supported identities and estimated proportions. Some entries may be chemical families rather than individual compounds. Proportions are semi-quantitative estimates, not quantitative measurements; a complete formula is not promised.

The data appendix records the methods used and supporting evidence. A separate account of what could not be determined explains unresolved components, overlapping findings and relevant sample limitations, so your team can judge what the report supports.

How to start

Tell us the product type and use, available sample quantity, any known formulation information, what you want to find out and whether a reference sample is available. We reply within 24 hours and agree the analytical scope before issuing a fixed quotation in USD.

Samples accepted worldwide; contact us before shipping. We confirm sample quantity, packaging and documents with you first. Samples already in China can go by domestic courier. Request an NDA before sharing confidential details if needed. The quotation confirms the project schedule and delivery arrangements.
