Poron Polyurethane Open-Cell Foam Sheet, Ultra Soft Firmness, No Backing, Black, 0.500" Thickness, 36" Width, 54" Length

Product Information

SS The high- resistance material, while similar to the Standard Series, is equivalent in softness to the SR-S grade. Its features excellent temperature dependence As a polymer with a closed-cell structure, it will not revert to an expanded state after it has been vacuum-sealed. It cannot be reused for other applications. RECOMMENDED USE

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 offer four series: Standard, LO/FR (Low out-gassing/Flame-retardant), PET support material) and Special surfaces. Standard series 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. CLOSED-CELL FOAM

Thin PORON Foam– PORON urethane foam is available in very thin grades often used for dust and splash seals for electronic devices. Once you have the screws out of the way (using the allen key included in the box), you will be able to access the internals of the keyboard. Front and center is the polycarbonate switch plate which is indented with flex cuts that makes the plate extremely flexible and bouncy, which as we will see truly helps with its gasket mount system. This polyurethane foam series is composed of the second softest PORON foams. Some of its softness is traded for higher tensile strength than the 4701-30 series. PORON Market Prefix – the family of products, for industrial grades the market prefix is usually 4701 or 4790.

PORON 4701-60 is not soft. This makes it unsuitable for cushioning a human body directly or any delicate electronic components. This foam also tends to swell when it absorbs water. It cannot be submerged. Moreover, this foam series is not particularly resistant to automotive fluids. RECOMMENDED USE Since open-cell design prevents deflation over time, PORON foam is frequently used in products designed to resist frequent, repeated impact. Running shoes and prosthetic limb interiors are good candidates for PORON foam and other open-cell polyurethane cushions. You can swap any of the foams in and out as you please to achieve the kind of sound profile you like. I usually do not touch the PCB foam and the switch pad as they have the most prominent effect on the sound, but I did try removing the bottom case foam and didn’t notice much difference except that it introduced a tad bit more bounce to the typing.

PORON® AquaPro™ – Enhanced Sealing PORON Foam

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.

This is one of the most durable PORON products. It resists tearing, corrosion, mildew, and bacteria. PROS As the lowest-density foam, you can use it as a seal on lightweight products, or within small gaps, without throwing off the item's weight. CONS PORON® Urethanes are patented open cell, breathable materials. The open cells act like tiny springs absorbing impact and providing cushioning to the body. PORON® Urethanes are designed to maintain their memory and continue to return to their original shape. The materials are resistant to moisture and other environmental conditions offering continued cushioning comfort in footwear, orthotic appliances, apparel and other applications.In the same vein, this foam safely seals high-pressure gaskets, even in extreme heat. It’s also valuable for car interiors, airplane seating, and running shoes. 5. PORON AQUAPRO™ CLOSED-CELL VACUUM SEAL 4701-41 The fit and finish of the EK75 is absolutely fantastic. Built from full aluminum construction it looks much more premium and sophisticated than its price tag might suggest (especially if you are used to gaming keyboards that are priced much higher and offer not even a tenth of its features). LCD screens, battery pads, cushions, and shoes are all typical uses for 4790-92. 11. PORON EVEXTEND® 4701-43 At CB Frost, typical applications for poron include dust, water and non-fogging seals for lighting fixtures, and door panel seals for a range of vehicles, as well as cushioning for an extensive range of electronic and communications devices.
