Speciality elastomer
FR Sponge Sheet
【 Features 】
・Excels in heat resistance.
・Excels in solvent resistance. (Particularly highly-polar solvent.)
・Excels in acid, alkali, alcohol, and oil resistance.
・Excels in weather and ozone resistance.
・Expansion ratio: Approximately 4.5 fold.
・Closed cell.
【 Applications 】
・Electronic parts and electrical parts.
・Various packing materials.
・Heat resistant cushion materials.
*Hardness measurement is revised to “After 3 seconds” according to JIS K 6253 (2006). However, generally, the conventional "measurement within 1 second" is to be the mainstream for nominal hardness, so this result is measured value and the measurement result after 3 seconds is shown in ().
