Request Expert

Expert is an expert in plastic piping, having in-depth knowledge of polyethylene pipe, PE gas pipe, PVC pipe, ABS pipe, crosslinked-polyethylene (PEX) pipe, polybutylene pipe, and related fittings. He is equally proficient with pipe joining processes using solvent cement and butt- and socket-fusion. He is an active member of the Plastics Pipe Institute, Plastic Pipe & Fitting Association and an officer in ASTM's F17 Committee on Plastic Piping Systems.

As manager of the largest plastic pipe testing laboratory in the US, Expert is deeply involved with plastic component failure analysis and testing for physical properties or environmental stress cracking and material degradation. He has been an invited lecturer to the US DOT Transportation Safety Institute to speak on plastic gas pipe failures. Many of his programs involve long-term plastic stress analysis and service-life prediction.

Expert possesses an intimate understanding of plastics materials, their properties and mechanical behavior, the relationship of stress, time, and environmental conditions, as well as an appreciation for the interdependency of material, product design, and processing techniques for the success or failure of plastic products.

Expert has knowledge of failure processes such as plastic stress cracking and degradation (oxidation, molecular weight reduction, and crosslinking), as well as the effects of creep and stress relaxation.

Expert has extensive experience with plastic testing programs which include most physical and chemical analyses routinely performed on plastics products and materials. He has developed new test methods for specific situations. Expert provides solutions to clients' problems through his knowledge of the materials and their behavior and an understanding of the processes for sample preparation and testing as well as the process effect on test results. He has been involved in several high profile patent infringement cases involving crystalline (isotactic) polypropylene, polyethylene copolymers, and polypropylene block copolymers, as well as several plastic product applications.

All of Expert's client programs require an extensive knowledge of the major thermoplastic materials, polymerization processes, formulation components (stabilizers, reinforcements, processing aids), structures (crystalline morphology, foams, composites, blends, alloys), processing methods, and applications. He keeps abreast on the latest technological advancements through in-depth literature reviews.

Expert's broad range of knowledge concerning the plastics industry touches on aspects of material properties, product manufacturing, and product testing. He has been involved with the design and development of plastic products for use in electrochemical processes as well as development and testing of ion-exchange membranes. He has also participated in developing electrically-conductive plastic moldings and coatings, sports products, and adhesives. Expert is also active on Geosynthetics, and has been involved with several client programs involving flexible PVC, HDPE, VLDPE, and elastomeric membrane liners, and was involved in the original NSF program to develop standards for these products.
