Speciality elastomer
SR Sheet (Silicone rubber)
Silicone Rubber Sheet
【 Features 】
・Excels in ozone resistance and weather resistance.
・Usable in wide temperature range of -60～200°C.
・Excels in insulation resistance.
【 Applications 】
・Parts for electronic device.
・Heat resistant packing material.
・Electric isolating sheet.
*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 ().
