Hieraus ge- tanzte Dichtungskörper können, falls Xulkanisa- tionsinittel zugesetzt wurden, ohne Vulkanisation sofort benutzt \verden, -,wenn sie bei ihrer VerNven- ching erhöhten Temperaturen ausgesetzt sind, weil dann dabei die Vulkanisation stattfindet. Man kann alter auch auf den Zusatz von Vtilkanisationsmitteln verzichten, weil die Dichtungskörper, auch ohne vtilkatiisiert zu sein, eine hinreichende Stand- festigkeit haben. Es ist überraschend, daß so hergestellte Dichtun- ge11 trotz des hohen Füllstoffgehalts eine gatte Standfestigkeit und hohe Elastizität besitzen. Ihre Temperaturbeständigkeit ist ausgezeichnet. Sie ertragen beispielsweise monatelang Temperaturen bis 25o° und zum Teil auch darüber.. Sie eignen sich für die Abdichtung von Gefäßen der verschiedensten Art und insbesondere bei Verwendung von Kautschuken, die gegen Chemikalien, z. B. Lösungsmittel, beständig sind, auch für die mannigfaltigsten Zwecke in der chemischen und verwandten Industrie.

The Koa <-ulat can be opened after drying a \\ 'alziverk zti pull out plates. From this danced sealing bodies can, if Xulkanisa- tion agents were added without vulcanization used immediately, - if, in their use, they ching exposed to elevated temperatures because then in the process the vulcanization takes place. One can age also on the addition of chemical treatment agents dispense because the seal body, even without to be vtilkatiized, a sufficient standard have strength. It is surprising that seals produced in this way ge11 a great one despite the high filler content Have stability and high elasticity. Their temperature resistance is excellent. For example, they can withstand temperatures of up to 25o ° for months and sometimes even above. B. solvents, are resistant, also for a wide variety of purposes in the chemical and related industries.

Es tritt allmählich Koagulation ein. Das Koagulat wird entwässert, getrocknet und auf der Walze zu Fellen ausgezogen. Aus diesen können die beschriebenen Dichtungskörper hergestellt «erden. Man kann auch die wäßrige Kautschukdispersion nur mit der angegebenen Menge Graphitpulver versetzen und das Koagulat dann entsprechend weiterverarbeiten. Die so erhaltenen Dichtungskörper zeichnen sich ebenfalls durch hohe Elastizität und Standfestigkeit aus.Example 400 parts of a 25% aqueous dispersion of an artificial Rubbers made from butadiene and stvrol are mixed with zoo to goo parts of graphite powder, 4.5 parts of colloidal sulfur and one part of zinc salt, four aminic acid added with stirring. Gradual coagulation occurs. The coagulate is dehydrated, dried and pulled out on the roller to make skins. From these, the described Seal body manufactured «earth. You can also use the aqueous rubber dispersion only add the specified amount of graphite powder and then the coagulate accordingly further processing. The sealing bodies obtained in this way are also distinguished high elasticity and stability.
