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 ().
