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, 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.
