Title (EN) NON-ASBESTOS FLEXIBLE SHEET MATERIAL
(FR) MATERIAU EN FEUILLE SOUPLE AUTRE QUE L'AMIANTE
Abstract:
(EN) Non-asbestos flexible sheet material suitable for use in gaskets for the cylinder head of an internal combustion engine is made by a paper-making process in which the aqueous slurry employed is substantially free from cellulose and contains the following ingredients in the following proportions by dry weight: kaolinitic clay comprising both ball clay and china clay 65-90 %, organic fibres consisting essentially of fibrillated poly(aromatic amide) fibres 5-15 %, polymeric binder, e.g. nitrile rubber 4-10 %.
(FR) Un matériau en feuille souple autre que l'amiante pouvant être utilisé dans des joints de culasses de moteurs à combustion interne est fabriqué selon un procédé de fabrication de papier dans lequel la bouillie aqueuse utilisée est pratiquement dépourvue de cellulose et contient les ingrédients suivants dans les proportions suivantes basées sur le poids sec: argile kaolinique comprenant à la fois de l'argile figuline et du kaolin 65-90 %, fibres organiques composées essentiellement de fibres de poly(amide aromatique) fibrillées 5-15 %, liant polymère, par exemple du caoutchouc nitrile 4-10 %.
