Polymer Expert Witnesses

Polymer disputes in commercial litigation typically arise in patent, product liability, and materials supply matters, when a company alleges that a competitor's polymer formulation or coating technology infringes a patent or that a polymer product failed to meet contractual material specifications. These disputes surface in patent infringement litigation over polymer chemistry, coatings, and composite formulations, in product liability litigation over whether a polymer product's material properties and processing met applicable engineering standards, and in commercial supply disputes over whether delivered polymer materials met the composition and performance specifications a contract required. Because polymer science spans chemistry, materials engineering, and processing disciplines, determining whether a specific polymer formulation, coating, or product met applicable standards requires specialized polymer chemistry expertise. The central issue is typically whether the polymer material, formulation, or coating at issue met the specifications and standards that governed it.

A polymer expert helps attorneys evaluate that question by applying polymer chemistry and materials science methods to the formulation or product at issue. That might mean comparing an accused polymer coating or composite formulation against a patent's claimed composition, evaluating whether a polymer product's material properties met applicable engineering and performance standards, or conducting spectroscopic and mechanical testing to determine whether delivered polymer materials met contractual specifications. These findings support positions on patent infringement, product liability, and breach of contract, giving attorneys a technically grounded basis for litigation strategy.

Polymer cases benefit from experts whose specific background, whether polymer chemistry and synthesis, polymer coatings and corrosion prevention, or polymer processing and characterization, matches the precise material and application at issue rather than polymers in general terms. Round Table Group's polymer network includes materials scientists and chemists with experience across polymer solid state structure, electrochemistry, and multicomponent polymer systems, several of whom have testified on PTFE, medical device, and coatings matters. With more than 75,000 expert searches completed for litigators, we help attorneys match a case's specific polymer issue to an expert whose credentials will withstand scrutiny. Let us help you find the right polymer expert for your case by calling us at (202) 908-4500.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Polymer expert witnesses for cases like:

01

The Resin Didn't Meet Spec.

A consumer products manufacturer sued its resin supplier after a new product line experienced widespread cracking in the field, alleging the supplied polymer failed to meet the specified impact strength and flexural modulus requirements. We identified experts with experience in polymer mechanical property testing, resin specification compliance, and plastic part failure analysis. The expert's testing of retained resin samples confirmed the material fell short of the specified impact strength, supporting the manufacturer's breach-of-warranty claim in a substantial settlement.
02

The Quality Records Didn't Hold Up.

An acquirer sued the sellers of a custom injection molding company after post-closing review found that a portion of the target's quality control testing records, cited throughout diligence as evidence of a clean compliance history, had been fabricated for several key customer programs. We identified experts with experience in polymer processing quality control, injection molding testing protocols, and materials testing documentation review. The expert's reconstruction of the testing records against underlying raw data confirmed a pattern of fabricated results, anchoring a substantial post-closing damages recovery.
03

Whose Polymer Formulation Was It.

A specialty polymer manufacturer sued a competitor alleging its newly launched high-performance compound infringed a patented polymer blend formulation designed to improve heat resistance without sacrificing impact strength. We identified experts with experience in polymer blend chemistry, patent claim scope analysis, and comparative material characterization. The expert's compositional analysis found the competitor's formulation fell within the patent's claimed compositional ranges, and the case settled with a substantial licensing arrangement.
04

Degraded Outdoors Faster Than Promised.

An outdoor furniture manufacturer sued its polymer supplier after products in the field showed severe embrittlement and discoloration years ahead of their represented service life, alleging the supplied resin lacked adequate UV stabilization for the intended application. We identified experts with experience in polymer photodegradation analysis, UV stabilizer formulation, and accelerated weathering test interpretation. The expert's analysis confirmed the stabilizer package was inadequate for the product's outdoor exposure profile, supporting the manufacturer's claim in a substantial settlement.
05

The Packaging Barrier Didn't Hold.

A food brand owner sued its flexible packaging manufacturer after a new pouch design failed to maintain the oxygen barrier properties specified in the packaging contract, causing a substantial share of a product run to spoil prematurely on retail shelves. We identified experts with experience in polymer film barrier properties, multilayer packaging structure analysis, and oxygen transmission rate testing. The expert's testing of the delivered film confirmed the barrier layer fell short of the specified transmission rate, supporting the brand owner's claim in a substantial settlement.
06

Not as Biocompatible as Certified.

A medical device manufacturer sued its polymer supplier after a component made from a supposedly biocompatible-grade resin triggered adverse tissue reactions during preclinical testing, delaying the device's regulatory submission by many months. We identified experts with experience in polymer biocompatibility testing, medical-grade resin certification standards, and material extractables and leachables analysis. The expert's testing identified leachable compounds inconsistent with the certified grade's specification, supporting the manufacturer's claim against the supplier in a substantial settlement.
07

Polymer Creep Nobody Accounted For.

An automotive OEM sued its Tier 1 supplier after a polymer housing component in an under-hood application showed a pattern of field failures traced to long-term creep deformation under sustained heat exposure, triggering a costly recall. We identified experts with experience in polymer creep and long-term mechanical property analysis, automotive under-hood material qualification, and component failure investigation. The expert's testing confirmed the material's creep resistance had not been adequately validated for the application's thermal profile, supporting the OEM's claim in a substantial settlement.
08

The Recycled Content Wasn't What Was Claimed.

A packaging company sued its resin supplier after independent testing revealed that material certified as containing a substantial percentage of post-consumer recycled content actually contained meaningfully less, jeopardizing the packaging company's own sustainability claims to its retail customers. We identified experts with experience in recycled polymer content verification, isotopic and spectroscopic material testing, and recycled content certification standards. The expert's testing confirmed the recycled content fell well short of the certified level, and the supplier agreed to a substantial settlement covering the packaging company's remediation costs.
09

The Additive Turned the Color.

A plastics compounder sued its colorant and additive supplier after a masterbatch caused unexpected yellowing and brittleness in a molded product line months after the additive supplier had approved it as compatible with the base resin. We identified experts with experience in polymer additive compatibility analysis, colorant and stabilizer interaction chemistry, and plastic discoloration failure investigation. The expert's analysis identified a chemical interaction between the additive and the resin's stabilizer package that the supplier's compatibility testing had failed to catch, supporting the compounder's claim in a substantial settlement.
10

Printed to a Different Standard.

An aerospace component manufacturer sued its polymer filament supplier after a batch of 3D-printed brackets failed mechanical testing, tracing the failures to filament with mechanical properties well below the datasheet values the supplier had certified. We identified experts with experience in additive manufacturing material characterization, polymer filament quality testing, and 3D-printed part mechanical property validation. The expert's testing of retained filament samples confirmed the material fell short of the certified tensile strength, supporting the manufacturer's claim in a substantial settlement.
