This series features low out-gassing and flame-retardant (UL94 HBF) with consideration to safety and environmental protection. The PORON 4701-60 is a very firm series of PORON foam. The series encompasses 4701-60-15, 4701-60-20, and 4701-60-25. It can deflect waves and vibrations for an extended period without losing shape or stiffness. This foam is easy to die cut with precision. It will retain its shape long-term after being cut. CONS

Customization needs can vary, and no two people want identical things out of their designs and materials. Curious about how to meet your custom industrial materials needs? You can read more about foam tape and other adhesive materials in our Learning Center. By filling small spaces, the AquaPro series effectively seals off components to prevent water damage. It meets and surpasses Federal Aircraft Regulation standards for sealants. 4. PORON 4701-40 POLYURETHANERogers Corporation, a global leader in materials development, has patented thirty-five PORON Industrial Polyurethanes. These open-cell polyurethane materials have solved unique engineering challenges, including filling gaps in the Hubble space telescope. The PORON 4701-40 polyurethane series can handle extreme temperature fluctuations without warping. This polyurethane can function in temperatures as low as -40ºC and as high as 121ºC. H is a hard product in the standard series. This type offers a high physical strength, being used as sealing materials or vibration dumping materials. The AquaPro™ PORON foam best meets hydrophobic needs. It effectively seals in and secures components that are likely to be exposed to water. PORON is a fine pitch open cell urethane foam produced by Rogers Corporation. The uniform, microcellular structure allows PORON to be easily compressed for dust seals and cushions. Water sealing with PORON is possible in applications with proper compression and moderate water exposure. The average cell size of PORON foam is approximately 100 microns.

Choosing a foam tape to put on your skin warrants an entirely different set of standards than choosing tape to seal an EV battery.

T The surface combines strong surface characteristics and excellent flexibility through special surface treatment technology The AquaPro™ series is only intermittently stable in high-heat (120ºC) conditions. For high-heat applications, you may want to select a different PORON foam. As we go through these types of PORON foam, you’ll learn what their purpose is and what factors you should consider before making any final product decisions. Rogers Poron Foam We do not recommend using 4170-60 to fill small gaps. Its firmness might prevent it from expanding precisely into the necessary shape in a small space. RECOMMENDED USE
