PORON® Microcellular Polyurethane Foam
PORON® Industrial Polyurethanes are a unique family of urethane foam developed by Rogers Corporation. Formulated for exceptionally elastic and highly predictable performance, an open cell structure provides superior recovery characteristics making it an excellent choice for many gasketing applications.
With excellent chemical resistance, PORON® effectively withstands common cleaning solvents. Rogers’ PORON® foam is low outgassing, non-fogging, and non-corrosive, enhancing the material’s suitability for enclosed environments. Additionally, with flame-retardant options, PORON® material is a reliable choice for applications involving electrical systems where fire safety is paramount.
Plus, it’s compatible with Merryweather Foam’s adhesive lamination services!
