Asbestos-Free Gasket Materials
In general, modern gasket materials consist mainly of a combination of different fibers and inorganic, high temperature-resistant materials bound together with synthetic rubbers. It is not possible to simply replace the chemical and physical properties of asbestos with other fiber materials. However, Victor Reinz alternative gasket materials exhibit a range of properties that provide a number of advantages for gasket design and construction.
Properties & Benefits
- Gas Tightness: Victor Reinz compressed sheet materials exhibit far better gas-tightness than asbestos-based materials—in some cases, by more than a factor of 10
- Chemical Resistance: In practically all cases, for operating temperatures up to 300°F (partially up to 570°F), the chemical resistance is better than that of asbestos-based gaskets
- Corrosion Resistance: The chloride content of asbestos-free gasket materials is considerably lower than those containing asbestos. This prevents corrosion damage to the sealed surface and increases the reliability of the sealed joint
- Conformability: Victor Reinz materials’ comparatively high compressibility results in good conformity to rough or uneven sealing surfaces. This provides a considerable improvement in micro and macro sealing irregularities in the sealed joint
Production of Victor Reinz Gasket Materials
Victor Reinz composite gasket materials are manufactured as high-pressure gasket sheets, using special calendars with one heated and one cooled roller. The raw composite mix of fibers, filling materials, and binders is first blended in kneaders or agitators before it is applied to the heated roller until the required material thickness has been achieved. The calendar rolls compress, dry, and vulcanize the material.
Consequently, the quality of these asbestos-free materials depend not only on their composition, but also on the manufacturing process employed. The duration and intensity of the initial mixing process, the roller temperature and pressure, and the rolling speed all have a definite influence on the physical and chemical properties of these asbestos-free composite gasket materials.
