Seals are intended to provide security permanently until they are removed.
Most of the time, seals need to be used for a long time, so the performance of the sealing material may weaken or even destroy the sealing effect over time, but industrial seals need long-term stability of safety performance.
The UNM’s technology allows the sealant to keep these seals at low risk. Our rugged sealants retain their mechanical properties because they are creep-resistant, able to withstand higher temperatures, and provide excellent material strength.
Polytetrafluoroethylene sealing material has the advantages of high temperature resistance, corrosion resistance, water resistance and other good characteristics which significantly improve the service life of mechanical sealing equipment and bearing capacity.
