Plastics Expert Witnesses

Start Plastics Expert Search

Plastics expert witness candidates are typically professional engineers with areas of expertise in materials science, polymer science, and/or chemical engineering. The selected expert could be a member of an industry organization such as the Plastics Industry Association, or the International Association of Plastics Distribution (IAPD). Plastics expert witnesses must have a deep understanding not only of the target technology, but also of market trends, market growth, market segments, and competitive landscape. It is also essential that an expert witness possess the ability to provide expert testimony in such a manner that a jury and judge can understand the factual evidence. 

A plastics expert witness often provides expertise in intellectual property matters, such as a patent infringement or a trade secret dispute. A plastics subject matter expert could also be called in on a product liability case involving materials failure, or a consumer safety or personal injury matter. Litigation support by a plastics expert witness could include materials testing, failure analysis, depositions, and courtroom testimony. In addition, clients may seek a plastics or materials expert for pre-litigation consultant work.

Cahn Litigation Services has been approached by numerous clients to locate expert witnesses to support plastic technology matters. Whether the case involves a medical device, injection molding, polymer characterization, polymer processing, rheology, rotational molding, polymer synthesis, tooling, coatings or thermoplastics, Cahn Litigation Services has the experience required to turn an expert witness search around quickly. The firm has an earned reputation of providing candidates with the right balance of expertise and testimony to support each unique project.
