Function, rubber sheet according to a use Conductive Rubber Sheet

Conductive Rubber Sheet 画像1

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.

Applications

  • ・Drawing board of automatic drafting machine.
  • ・Suited for tables and etc. to write words.
Function ・ Conductive Property

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 ().
