Style 940 is a high-tensile, compressed NBR/aramid reinforced fiber sheet. 940 is a great general-purpose material that offers extras such as suitability for use as extremely large gaskets and pads, small, thin, intricate gaskets, or dielectric materials. Because of the high tensile strength and flexibility, 940 can be cut to exact dimensions without causing ragged edges or undue stress or wear on metal edge dies and gasket cutting equipment. This flexibility also enables the gasket to be cut into large or small intricate gasket without concern for breakage during fabrication or installation.
