Special Properties
Molykote 6169 demonstrates superior resistance to chemicals and solvents, enabling it to withstand aggressive media. Its high-temperature stability is excellent, showing only 1.3% evaporation loss after 1000 hours at 200°C. It also offers good extreme pressure and anti-wear properties, with a four-ball weld load of 3,630 N.
Important Safety Note: At temperatures exceeding 250°C, the material will gradually decompose and release toxic gases.
Application Scenarios
Molykote 6169 Grease is developed for valve seals, O-rings, and bearings in extremely harsh environments. Typical applications include:
- Process control valves, pump bearings, and seals in the chemical and petrochemical industry
- Components handling liquefied natural gas (LNG)
- Equipment in high vacuum environments required for semiconductor manufacturing
- Components in aerospace and automotive industries exposed to high temperatures, chemicals, or fuels
