Synthetic rubber

SBR Sheet (Styrene-butadiene rubber)

【 Features 】

•Excels in cold resistance
•Excels in heat resistance

【 Applications 】

•General packing and gasket material

*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 ().
