Authority on plastics, microplastics, environment

Specialties & Experience of this Expert Witness

Additional Information

Dr. DeArmitt obtained a BSc (Hons) in chemistry with polymer science from the University of Sussex, United Kingdom. He then obtained his MPhil and PhD on the topic of conductive polymer colloids, also from the University of Sussex. A very wide range of analytical techniques were used to characterize the new polymers and colloids made. He has over 30 years of industrial experience in plastics and formulation of plastics including additives such as fillers, reinforcements, antioxidants (stabilizers), impact modifiers and slip aids. Dr. DeArmitt was Manager of the Polymeric Materials Group at the Institute for Surface Chemistry in Stockholm. He created multi-national, multi-client projects on the topics of polymers, mineral fillers and antioxidants. During that time, he worked with the KTH Stockholm to create new hyperbranched, high molecular weight antioxidants to provide extraction resistance and long-term performance. He was Senior Project Manager at Electrolux (known as Frigidaire in the US) in which capacity he led a team to optimize Carboran, a polypropylene material which Electrolux uses in amounts exceeding 55,000 metric tons (over 120 million pounds) per year. Optimization of the fillers and antioxidant package were major topics. Later, Chris ran a project which identified new natural antioxidants for polypropylene. As Global Product Development Manager at BASF’s headquarters in Germany, Dr. DeArmitt worked on a wide range of polymers including competitor analysis, new product creation and new additives to give extended durability. Several patents resulted. As President of Phantom Plastics LLC based in Ohio, USA, Dr. DeArmitt creates new plastic materials, solves problems and provides training to well-known companies like P&G, Apple, LEGO, Exxon, Disney, Total, Eaton and more. In 2020 he released The Plastics Paradox book and is now considered an authority on the effects of plastics and microplastics on the environment. In 2024, Dr DeArmitt founded the Plastics Research Council, a nonprofit 501(c)(3) organization consisting of respected international scientists with a mission to share science around plastics and the environment to dispel misinformation. In 2025 he published the book Shattering the Plastics Illusion, an independent, unfunded review of over 5000 studies about plastics, microplastics and their effects on the environment. The book has been endorsed by professors world-wide. Publications to date include 3 encyclopedia chapters, 7 book chapters, 3 books over 40 articles and 15 granted patents. He was elected Fellow of the Institute of Materials, Minerals and Mining (FIMMM), Fellow of the Royal Society of Chemistry (FRSC), a Chartered Chemist (CChem) and a Member of the National Association of Environmental Professionals.
