Case Studies in Polymer Reverse Engineering Service: Success Stories and Lessons Learned

What is Polymer Reverse Engineering?

Polymer reverse engineering is a process where scientists break down and analyze plastic or rubber materials to understand how they’re made. This includes identifying:

• The base polymer
• Additives like stabilizers, colorants, or plasticizers
• How the material behaves with heat or chemicals
• Molecular weight and how it’s distributed

It’s often used to:

• Recreate competitor products
• Investigate product failures
• Improve existing formulations
• Ensure regulatory compliance

🧪 Case Study 1: Understanding a Medical Catheter Material

Client Problem:
A medical device company wanted to copy a flexible and solvent-resistant catheter but didn’t know what materials were used.

Our Solution:

• We used FTIR and DSC to find the polymer blend.
• TGA revealed heat stability and additive loss.
• GC-MS detected plasticizers and stabilizers.
• GPC helped find the molecular weight.

Result:
We helped them replicate the material successfully for FDA submission after doing extractables/leachables testing.

🔧 Case Study 2: Cracking in an Automotive Gasket

Client Problem:
An automotive supplier reported cracks in rubber gaskets under heat.

Our Solution:

• DSC & TGA showed poor heat resistance.
• FTIR identified degraded NBR rubber.
• SEM-EDX detected contamination by chlorine.
• The root cause was traced to PVC contamination.

Result:
The client changed their process and materials, fixing the issue.

🎥 Case Study 3: Recreating a Barrier Film for Packaging

Client Problem:
A startup wanted to replicate a competitor’s 5-layer plastic film that blocked oxygen well.

Our Solution:

• Microscopy mapped film structure.
• DSC & FTIR identified materials (like EVOH).
• GC-MS revealed additives.
• We studied the surface treatment (like corona discharge).

Result:
We provided a full report to help their manufacturer recreate the film.

🧰 Techniques Used in Reverse Engineering

Here’s a list of methods we use to study unknown polymers:

Technique	Purpose
FTIR	Find polymer type by functional groups
DSC	Check melting point and glass transition
TGA	See how material behaves when heated
GC-MS	Detect additives like plasticizers or antioxidants
GPC	Measure molecular weight
SEM-EDX	Analyze fillers and surface composition

Each case may need a different set of tools depending on the complexity.
