Composed of graphite yarn with a high content of carbon 99%, which is twisted and doubled with several ends, this product is a very flexible packing that resists stress and bending without losing volume and without crystallizing at high temperatures. Our very high quality yarns are subjected to a pre-treatment during production with a special blend of graphite in dispersion, with the addition of corrosion inhibitors. It is not affected by temperature variations, does not lose weight or volume and is elastic.
