Abstract
A tape having a first face comprising a continuous surface of mica paper and a second face comprising a support layer, wherein the mica paper comprises 70 to 99 weight percent mica and 1 to 30 weight percent binder and the support layer comprises a film, a paper, a nonwoven fabric, or a woven fabric; wherein the initial elongation of the support layer is equal to or less than the initial elongation of the mica paper; and wherein the support layer is demountably attached to the mica paper such that when a delamination force of 10 N/10 mm or less is imposed on the support layer it can be separated from the mica paper.
Claims5
A tape having a first face comprising a continuous surface of mica paper and a second face comprising a support layer,
- wherein the mica paper consists of 70 to 99 weight percent mica and 1 to 30 weight percent of a binder of aramid fibrids, and optionally, additive fibers or floc;
- and the support layer comprises a film, a paper, a nonwoven fabric, or a woven fabric;
- wherein the initial elongation of the support layer is equal to or less than the initial elongation of the mica paper;
- and
- wherein the support layer is demountably attached to the mica paper such that when a delamination force of 10 N/10 mm or less is imposed on the support layer it can be separated from the mica paper,
- wherein the support layer can withstand a tensile force of at least 50 Newtons per 10 millimeters of width.
