ERJ Compounding 2026: Developing PFAS Compliant Elastomeric Materials for Hydrogen Service

The global transition to a low-carbon energy system has accelerated the search for clean energy carriers, with hydrogen gaining prominence due to its high energy density and potential to reduce greenhouse gas emissions. However, hydrogen’s unique physical properties pose stringent demands on engineering components, including elastomers used as seals, gaskets, membranes, and hoses. Conventional rubber formulations often suffer from hydrogen-induced swelling, blistering, and cracking, particularly under cyclic pressure exposures or in low-temperature service. A technical paper by Nithin Sebastian Kuncheria of Clwyd Compounders examines the formulation, performance requirements, and material selection strategies necessary for developing elastomeric compounds tailored for low-temperature hydrogen service. The paper aims to support the creation of safer, more durable materials for next-generation hydrogen systems by understanding hydrogen-rubber interactions, permeation, and decompression mechanisms, as well as compounding principles and test methodologies. The development of PFAS compliant elastomeric materials is a key focus of the paper, with the goal of creating materials that can withstand the challenges of hydrogen service.
