We have extensive experience in plastic and polymer analysis and processing. Our polymer and plastic testing experts have investigated a wide range of polymeric materials, including:
Thermoplastics
Thermosets
Elastomers
High-performance polymers
Specialty polymers
Rubbers
Composites
Polyurethanes
Adhesives & sealants
Paints & coatings
In our labs, we use analytical instrumentation such as FTIR, GC/MS, GPC, LC/MS, Optical Microscopy, NMR, SEM/EDS, mDSC, XPS, ToF-SIMS and Pyrolysis-GC/MS. Our experts have years of experience interpreting this data to investigate challenges such as:
Contaminant or impurity identification
Analysis of raw materials
Comparison analysis
Compositional analysis
Deformulation (reverse engineering)
Suspected failures
Identification of suspect materials
Off-odor, off-color problems
Product failures
Our polymer analysis and testing capabilities range from obtaining basic information to more detailed and structurally specific results. Depending on our clients’ needs, we can offer a strategic combination of physical and chemical testing to answer specific questions. Physical properties analyzed have included:
Tensile properties
Adhesive strength
Compressibility
Cross-sectional multiple layer-film thickness
Thermal properties (including glass transition, melting point, thermal expansion and crystallinity)
Services for testing plastics and polymer materials for chemical properties include:

Plastic Testing Case Studies:
Heat Seal Adhesive Failure Analysis
Our client’s new heat seal adhesive was not providing a hermetic seal and released after only a few days. Faced with production line shut-down and delayed shipments, the customer called EAG. They suspected that the new adhesive’s formula, a polyurethane-acrylic hot melt adhesive, was the reason for the failure. Our expert chemists deformulated both the old formula and the new formula. The results showed significant differences in the molecular weight and molecular weight distribution, as well as the urethane-acrylic ratio. After concluding that these variations were the reason for the adhesion failure, we recommended a formula adjustment. The revised formula performed well, and the customer was able to resume operations.
The Sky is Falling
A manufacturer of light fixtures received complaints about fluorescent tubes falling out of overhead light fixtures. The failed fixtures showed large fractures in the plastic components that held the fluorescent tubes in place. There was also a white powdery residue on the plastic components. Our scientists identified the white residue, confirmed the composition of the failed plastic components and in discussions with the manufacturer, determined that the white residue was from chemicals used in the facility where the failures occurred. The chemical giving the white residue was reacting with the plastic components and breaking down the structure of the polymer. This information helped the manufacturer take proper corrective action.
