ESi’s polymers and composites team provides consulting related to materials, manufacturing, and products to clients across a broad range of industries.
Our experts have in-depth technical knowledge of best practices in design and manufacturing to assess the appropriateness of the materials for the intended application, and to provide service lifetime predictions of products.
The state-of-the-art laboratory capabilities in our offices around the country are used to characterize materials, determine atomic level chemical changes, and to study how those changes affect product performance. The work we do for our clients is then peer-reviewed by other members of our team to ensure its accuracy before use.
The results of ESi’s investigation were used to recommend and substantiate to the USAF Technical Airworthiness Authority (TAA) a return to pressurized flight without altitude restrictions.
ESi was retained to investigate the failure of a PVC pipe. The pipe showed indications of rapid crack propagation that would be consistent with a high-pressure event. In order to understand the effect of the pre-existing crack on the remaining strength of the pipe, a fracture mechanics analysis was performed.
A large cross-linked polyethylene (XLPE or PEX) storage tank for 93% sulphuric acid failed after approximately seven months of service. The release of acid occurred through circumferential cracks that developed on the bottom panel of the tank near the corner radius with the sidewall.
ESi was retained to perform a study on the degradation of HDPE piping resulting from exposure to the disinfectants used in potable water.
ESi was retained to determine the cause of failure of a woven polypropylene (PP) belt.
This course will educate claims and litigation personnel on what to look for in determining who may have responsibility and liability for incidents involving butane appliances and containers.
Overview: Contamination—we've all seen it in some form. In this presentation, we will explore various methods of identifying contaminants and their sources.
When components fracture, fatigue is often the reason. Ron Parrington walks you through the definition and types of fatigue, how to design and test for fatigue, and common fractographic features in fatigue failures.
ESi's expertise spans dozens of industries and specializations organized across several practice groups, each staffed by dozens of in-house experts with the technical knowledge, hands-on expertise, and courtroom experience required to execute projects for and with our clients from start to finish.Find an Expert Contact Us
