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 ().

  • EC-8N (Cloth-inserted) Sheet Resistivity Value 108Ω•cm Type

    【 Features 】

    •Construction without back or front making it free of "distortion" and "warpage" caused by prolonged use.
    •In addition to the high surface hardness, polyester cloth is filled in the middle making the movement of asters and trucks smooth.
    •NBR formulation makes it excellent in oil resistance and chemical resistance.
