Product made from fine weave pure cotton fabric and phenolic resins. Given its composition lends itself to the construction of small details and still can be used where they are required delicate and precise machining. Has discrete dielectric characteristics and therefore can be used for low voltage equipment. Easily sheared at room temperature up to a thickness of 1.5 to 2 mm, and after heating it at 100°C for greater thicknesses.
