For seals which are subjected to high pressure are impregnated by cotton fabric for improved extrusion resistance. The fabric structure forms micro lubricating pockets, resulting in lower friction values; thus helping to reduce wear. The fabric are coated with unvulcanised rubber solutions of NBR & FPM depending on the application of the seal. |
