Solving Polymer Failures Through Materials Chemistry
A part that cracks, warps, or degrades ahead of schedule. A supplier change that throws off process consistency. A competitor's product that outperforms yours. You need to know why.
Premature failures are more than just an inconvenience; they are costly business and engineering problems. In polymers and plastics. Material performance gaps most often stem from material composition, processing, or both. The real questions are:
- Where in the material lifecycle did something go wrong?
- What chemical or processing variable caused the deviation?
- What corrective action needs to be taken?
When material performance is understood at the chemical level, failures become solvable problems, not expensive surprises.
Polymer Failure: From Raw Material to Root Cause
RJ Lee Group's testing and characterization work is differentiated by over 30 years of advanced analytical instrumentation and team of experts to identify:
-
Material Composition
-
Additions
Whether you're developing a new product, resolving a production issue, or investigating a field failure, our approach combines advanced characterization techniques with deep materials science expertise to get you a clear, actionable answer.

Answers at Every Stage of the Product Lifecycle
Whether you're developing a new product, troubleshooting a production issue, or verifying material quality, our scientists provide the analytical support to keep things moving:
Material Characterization
Know exactly what's in your material and how it will perform. We provide detailed compositional and thermal analysis of polymers, additives, and fillers so you can make formulation decisions, verify supplier materials, or benchmark against competitors with complete confidence.
Material Selection
Choose the right polymer the first time. We evaluate potential materials based on your specific needs, production constraints, and regulatory requirements, helping avoid expensive reformulations or field failures down the road.
Manufacturing Support
Get to the root cause fast. When production problems like surface defects, brittleness, discoloration, contamination, or dimensional instability occur, we identify exactly what went wrong and deliver actionable recommendations so you can fix the issue and keep it from coming back.
Environmental and Safety Compliance
Stay ahead of regulatory requirements. We help you verify that your materials and finished products meet applicable environmental and safety standards throughout the product lifecycle, from raw material screening to end-of-life considerations.
Polymer Composition and Quality
Confirm that what you're shipping or receiving meets spec. We perform compositional verification, incoming material inspection, and lot-to-lot consistency testing to ensure raw materials and finished products conform to internal standards, customer requirements, and industry specifications.
