PORON® Foam & Cellular Urethane

High-Performance Microcellular Urethane for Sealing, Cushioning & Gap Filling

PORON® microcellular urethane foam is engineered for applications requiring long-term compression performance, vibration dampening, and reliable environmental sealing.

Stockwell Elastomerics fabricates custom PORON® foam gaskets, pads, and cushioning components for demanding OEM applications.

Designed for durability. Built for consistent performance.

Why PORON®?

PORON® cellular urethane is often specified when applications require vibration damping and cushioning or gap filling across a varied surface. For projects requiring thin profile designs with reliable rebound, Poron offers standard thicknesses as thin as .032” THK.

Unlike many foam materials, PORON® maintains mechanical properties over extended service life — even in dynamic or high-cycle applications.

Custom Fabrication Capabilities

We manufacture PORON® using a variety of production methods including waterjet cutting, precision die cutting, flash cutting, compression molding, and liquid injection molding. The production method employed for your project varies depending on the part. Liquid Injection Molding (LIM) can be suited for complex geometries, while flash cutting is used only for adhesive-backed parts. Waterjet cutting may be used early on in development for rapid prototyping but also may be suited for smaller runs or narrow part geometries.

Die cutting of PORON® cellular urethanes is part of our core fabrication capabilities.

In-house engineering and manufacturing allow for quick-turn samples and consistent production quality.

Common Applications

PORON® foam is frequently used in:

  • Electronics enclosures and portable devices
  • Medical diagnostic equipment
  • Industrial and telecom systems
  • Automotive and EV charging systems
  • Semiconductor and analytical instrumentation

Applications often require controlled compression, vibration isolation, and reliable sealing against dust or incidental moisture.
