Donit Tesnit Standard Line
The Donit Tesnit standard line of compressed gasket materials are the high quality materials produced on specially designed rollers called calanders. A pasty mixture of material is placed into the gap between a large heated roller and a small cooled roller, until the desired thickness is achieved. The quality of gasket materials produced in the calandering process is influenced by the following main parameters: working pressure, temperature of the rollers and speed of the rollers. Donit Tesnit Standard Line of compressed gasket materials consist of fibres and fillers which are bonded together by rubber. The final properties of compresed gasket materials are also in connection with: quality and quantity of the fibres, the degree of openness of individual fibres, and the amount and the type of fillers and rubber used.
