Function, rubber sheet according to a use Conductive Rubber Sheet
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.

*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 ().
