Low compression set– PORON cellular urethane has superior resistance to taking a compression set as compared to neoprene sponge or polyethylene foam. Less than 2% at 73°F and less than 10% at 158°F makes PORON an ideal gasketing material for many indoor enclosure applications where dust, light and incidental splash sealing are required. Thin PORON Foam– PORON urethane foam is available in very thin grades often used for dust and splash seals for electronic devices. This series encompasses both PORON 4701-30-20 and PORON 4701-30-25. The impact foam PORON XRD is part of the 4701-30 series and lightweight enough to fit into apparel. PROS
Over time, repeated compression causes air to leak out of the closed cells. Because the cells shut it out, air cannot return to the foam. This process of exhalation deflates the foam. OPEN-CELL VS.

The extra soft nature of this foam extends its life. It also keeps it lightweight while still effectively absorbing low-energy impacts. 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. Due to its effective vibration isolation, 4170-50 polyurethane foam serves the dual purpose of dampening sound and managing impact.
This series features low out-gassing and flame-retardant (UL94 HBF) with consideration to safety and environmental protection. You want your flexible materials to be easy to work with. PORON foam can be effortlessly cut and manufactured and plays nicely with adhesives and other materials. This flatter curve works with the battery's natural cycle of contraction and expansion. To absorb and distribute force effectively when the degree of compression is constantly changing, the Rogers corporation developed foam with a firm-to-soft gradient in each individual piece. Strouse has helped prototype hundreds of parts using different variations of foam tape, and we know how to find the right fit for the job. Compression lets the polyurethane springs condense, and air moves freely from the space. Meanwhile, the remaining air can support the pressure point within the micro-coils.
What is PORON®?
The PORON EVExtend® is a material intended to cushion the batteries of electric vehicles. Its most unique property is its flatter compression force deflection (CFD) curve. It isn’t very soft or flexible or notably resistant to mildew or bacteria. This series is not well-suited to contexts where it will be continuously exposed to dampness. RECOMMENDED USE PORON 4701-60 is not soft. This makes it unsuitable for cushioning a human body directly or any delicate electronic components.
