Conductive Rubber Sheet
EP Sheet (EP-2 Type, EP-5 Type)
【 Type 】
| EP-2 | Resistivity Value 102Ω•cm Type (Material : 3 types : Natural rubber, CR system, NBR system) |
|---|---|
| EP-5 | Resistivity Value 105Ω•cm Type (Material : 3 types : Natural rubber, CR system, NBR system) |
*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 ().
