PORON® microcellular polyurethane foams from Rogers
Corporation are the industry standard for high-performance
sealing, cushioning, and vibration management. Known for
their exceptional compression set resistance, long-term
durability, and ability to maintain a consistent seal over
time, PORON® materials are engineered for environments
where failure isn’t an option.
Available in a wide range of thicknesses, firmness levels,
and performance grades, PORON® materials are ideal
for managing pressure, absorbing impact, and dampening
vibration – especially in automotive, electronics, medical,
and industrial applications. As a Rogers Preferred Converter,
SMI transforms Rogers’ PORON® materials into custom
parts tailored to your exact design needs.
