Polymer Deformulation & Reverse Engineering Analysis
A polymer product is rarely just one resin. Its performance may depend on the base polymer, fillers, plasticizers, stabilizers, antioxidants, pigments, flame retardants, reinforcing materials and other additives used at different levels.
Xinbodi provides polymer deformulation services to help manufacturers understand what is actually inside a polymer material and, more importantly, what those differences may mean for product performance.
What Are You Trying to Find Out?
The material still carries the same grade name, but the finished product suddenly processes differently, cracks more easily, changes color or no longer performs as expected.
In this situation, simply confirming the polymer type is usually not enough.
A comparative deformulation study can investigate differences in:
- Base polymer or polymer blend
- Molecular characteristics
- Filler type and loading
- Plasticizer level
- Stabilizer and antioxidant package
- Pigments and inorganic components
- Trace additives or contaminants
Whenever possible, we recommend sending both the previous good material and the current material for direct comparison.
“I Want to Reconstruct the Formulation”
Polymer deformulation can often identify the major formulation system and estimate important component levels.
| What You Want to Know | What We May Determine |
|---|---|
| Base material | Polymer family, blend or copolymer |
| Fillers | CaCO₃, talc, glass fiber, carbon black and others |
| Filler loading | Approximate wt% where feasible |
| Plasticizers | Identity and approximate concentration |
| Stabilizers | Antioxidants, UV stabilizers and related additives |
| Flame retardants | Organic or inorganic flame-retardant systems |
| Pigments | Pigment or elemental composition |
| Other additives | Processing aids, lubricants and selected trace components |
| Overall formulation | Practical formulation framework for further validation |
“A Competitor's Material Performs Better”
The useful question is usually not:
What polymer is this?
It is:
Why does this material perform differently from ours?
The difference may come from the resin itself, molecular weight, filler loading, reinforcing material, plasticizer, stabilizer package or another formulation component.
By comparing your material with a reference or competitor sample, we can help identify the compositional differences most likely to explain the performance gap.
Sometimes the goal is not to reproduce an entire formulation.
You may simply need enough information to determine whether another supplier’s material is technically comparable to the material you currently use.
Polymer deformulation can help establish a practical material profile including:
polymer matrix + filler system + key additives + approximate component levels + relevant structural differences
This information can support supplier screening, imported-material replacement and raw-material qualification.

How Polymer Deformulation Testing Is Designed
Polymer deformulation usually requires more than one analytical technique because different components behave very differently.
Rather than applying the same test package to every sample, the analytical plan is built around the question you need answered.
What is the polymer matrix?
Techniques such as FTIR, NMR, DSC or Py-GC-MS may be used to identify the base polymer, blends or structural characteristics.
What fillers or inorganic materials are present?
TGA, SEM-EDS, XRD, XRF or ICP-based techniques may help identify and quantify mineral fillers, reinforcing materials and inorganic additives.
What organic additives are present?
Extraction combined with GC-MS or LC-MS can be used to investigate plasticizers, antioxidants, stabilizers and other organic formulation components.
Why do two polymer samples behave differently?
A comparative project may combine composition, thermal, molecular and microscopic analysis to determine which differences are technically meaningful.
The objective is not to run more tests. It is to generate enough evidence to answer the specific material question.

Not Sure How Far the Analysis Needs to Go?
You do not always need a full polymer deformulation study.
If you only need to confirm the polymer type, compare two suppliers or investigate one suspected additive, a smaller analytical scope may be sufficient.

What You Will Receive
Depending on project scope, a polymer deformulation report may include:
- Identified base polymer or polymer blend
- Detected fillers and reinforcing materials
- Organic additive identification
- Estimated component levels where technically feasible
- Instrumental data and representative spectra
- Side-by-side comparison of multiple samples
- Interpretation of important formulation differences
- Possible formulation framework

FAQs
Can polymer reverse engineering identify the exact resin grade or manufacturer?
Polymer reverse engineering can often identify the polymer family, blend or copolymer system, molecular-weight characteristics, fillers and key additives. However, identifying the exact commercial resin grade or manufacturer is not always possible because different suppliers may offer chemically similar materials with different molecular-weight distributions, catalyst systems or proprietary additive packages.
In many projects, the goal is to identify a technically comparable resin system rather than a specific brand name.
Can polymer deformulation explain why two plastics with the same polymer type perform differently?
Not always. Major ingredients and many minor components can often be identified, while trace additives, proprietary mixtures or very low-level components may require additional targeted analysis.
Xinbodi combines multiple analytical techniques and has access to more than 1,000 analytical instruments, allowing complex formulations to be investigated from different chemical, thermal and structural perspectives.
Can chemical reverse engineering determine the exact formula of a product?
In many suitable projects, chemical reverse engineering can reveal the major formulation structure and quantify key components with a high degree of accuracy.
Xinbodi’s formulation reconstruction rate can exceed 90% for technically suitable samples. However, an exact 1:1 formula cannot always be guaranteed, especially when trace additives, proprietary raw materials or complex reaction products are involved.
What is the difference between composition analysis and deformulation?
Composition analysis is generally used to identify what materials or chemical components are present in a sample.
Deformulation analysis goes further by separating complex formulation fractions, identifying key ingredients, estimating or quantifying their levels, and interpreting how the components work together.
For clients seeking formulation reconstruction, competitor benchmarking or product redevelopment, deformulation is usually the more appropriate approach.
Can you reverse engineer a competitor’s product?
Yes. Chemical reverse engineering services are commonly used for competitor benchmarking, formulation comparison and product development.
Xinbodi has supported more than 10,000 clients worldwide with formulation analysis and reverse engineering projects across chemicals, polymers, coatings, cleaners, cosmetics, lubricants and other formulated products.
Can deformulation help compare suppliers or different production batches?
Yes. Deformulation and comparative analysis can be used to investigate differences between:
- Supplier A and Supplier B
- original and replacement materials
- normal and abnormal batches
- your product and a competitor product
The analysis can help identify changes in ingredient type, concentration, impurities, additive systems or formulation balance.
How much sample is required for deformulation or reverse engineering?
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.
Can international clients send samples to Xinbodi for reverse engineering?
Yes. Xinbodi accepts samples from clients worldwide for deformulation and chemical reverse engineering analysis.
We have supported more than 10,000 clients globally, and international clients can contact our technical team before shipping to confirm sample quantity, packaging requirements and the recommended analytical plan.
Is my sample and formulation information confidential?
Yes. All samples, formulation information, test data, and project details are handled confidentially. Xinbodi can sign a Non-Disclosure Agreement (NDA) with clients before the project starts to protect proprietary formulations and sensitive R&D information.
