When a gasket or rubber component is subject to chemical attack and/or very high temperature, a perfluor elastomer of the OLD-REX (FFKM-FFPM) series must be used.
In fact, under the stated conditions, these materials offer the best performances attainable with an elastomer, if compared to other rubbers.
Only Oldrati articles made in this special series can guarantee absolute chemical resistance to a wide range of products or chemical compounds; moreover, by using specifically formulated materials, it is possible to attain exceptional heat resistances, sometimes even exceeding 320° C.
These extraordinary performances depend on the fact that these elastomers boast the same stability and behaviour as polytetrafluoroethylene (PTFE) better known with the trademark TEFLON by Du Pont.
The use of articles made with products of the OLD-REX series undoubtedly improves the process, that translates into greater efficiency of the sealing system, improved safety and, therefore, an overall economic saving.
