Microcellular Polymer Sheets PORON®




	HOME > Products > Microcellular Polymer Sheets PORON®

Microcellular polymer sheets, PORON®, are products manufactured by Rogers-INOAC Corporation, a joint venture between INOAC Corporation, Japan, and Rogers Corporation, U.S.A. PORON® products, high performance urethane foam materials, feature a unique cell structure with high levels of density, minuteness and uniformity.

Here is Application NAVI for each segments.

PORON® has very low compression set.

PORON® provides high sealing performance.

PORON® offers excellent impact absorption.

PORON® has very no migration effect on other materials.

PORON® provides excellent dimensional stability.

PORON® is a material with high fabricating efficiency.





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.


L is a softer product in the standard series, being used for a wide range of cushioning and packing materials.


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.





MS is a product similar to the LE type in the standard series. It is one of the softest materials among the LO/FR series, allowing for production of very thin products.


ML is a soft material similar to the L type in the standard series.


MH is a hard material similar to the H type in the standard series.





SR-S, produced by integrally molding PET film and SR compound that offers low resilience, is a material with proper softness and rigidity.


ASRS is a material to which antistatic characteristics have been added. It inherits SR-S's superior characteristics such as low resilience, thinness, as well as rigidity that comes from the integral molding with PET. ASRS is suited for the use in products that need to prevent static electricity.


Slow-rebound, flame retardant type is also available complying with UL 94 HBF.


SS is a new grade material that features the same hardness as the SR-S type, while retaining the same level of resilience as the PORON® Standard series.


MS/MH is produced in the process where types MS and MH in the LO/FR series are integrally casted onto PET film, offering the same high degree of resilience as conventional PORON® products.






This is a hard type of material with a good overall balance.


HH, a super hard type, is very hard and provides very high load bearing capability.


This is the hardest material among the Foot Pad series products, offering the load bearing property equivalent to that of solid materials. It also provides excellent gripping forces due to the HF coating.





LE-20LF is a material produced by applying a special surface treatment to the LE type of the Standard series. This product provides improved levels of surface slip characteristics, non-adhesiveness and also excels in preventing friction noises.


Flame resistant hardest type: Hardest type in the PORON® Foot Pad series, offering excellent load bearing characteristics. This type provides a stable and high gripping force due to HF coating.
