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

Product Information

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 Due to its effective vibration isolation, 4170-50 polyurethane foam serves the dual purpose of dampening sound and managing impact. PR A thin adhesive mechanism is integrated into the casting process which providesa light adhesive force after the PET film is removed. It can be used as a temporary fixing or setting point in a repetitive process, and it improves workability

Because it can maintain its integrity, this foam is an effective choice for dealing with vibrations, energy, and sound from atypically shaped sources. It can endure long-term vibrations all while remaining molded in its correct form. 7. PORON 4701-60 POLYURETHANE Thin PORON Foam– PORON urethane foam is available in very thin grades often used for dust and splash seals for electronic devices. 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 For more information on PORON® products or for advice in selecting the best suited material for your application, you can call our knowledgeable sales team on +44 (0)121 773 8494 and we will be glad to assist you. We offer four series: Standard, LO/FR (Low out-gassing/Flame-retardant), PET support material) and Special surfaces. Standard seriesWe 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 Presenting PORON PLUS, based on ROGERS INOAC CORPORATIONS’s own in-house technology. Special blending technology 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.

If your equipment or machinery needs to resist chemicals and other liquids, PORON foam is the answer due to its low outgassing status. Rogers 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 4701-50 line of polyurethane foams is firm. These foams are made for high-impact, high-energy gaskets.This soft foam ranges in density from 144 kg/m³ to 480 kg/m³. It can function in temperatures as low as -20ºC and in environments where the maximum temperature reaches 121°C It is also flexible. The combination of firmness and flexibility allows it to absorb impacts precisely, even in a small space. PROS

The most common use of 4701-43 is as a battery pad inside electric vehicles and hybrids. This foam could be used for filling gaps, gasketing, and sealing. It can also be manipulated into a different type of cushion. 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.

HH is a harder product, primarily being used for the foot pads of audio devices, home electric appliances and office appliances. The C type that has excellent gripping property is also available. CH is a hard material which is similar to the H type in the standard series. Additionally, EG type (special surface treatment ) is also available

T The surface combines strong surface characteristics and excellent flexibility through special surface treatment technology You’ll likely wish to apply PORON 4701-30 with the most effective adhesive. Especially in more finely tuned applications, you want to ensure your adhesive doesn't add any unnecessary bulk, especially since you're using such a lightweight product.LE is the softest product in the standard series. With its low stress property and compressibility, this type has been widely used for toner seals.
