PFPE High-Temperature Long-Life Grease CAS 9002-84-0, Perfluoropolyether PTFE -40~260℃ for High-Temp Bearing Chemical Equipment
This PFPE high‑temperature long‑life grease is a fully fluorinated lubricating grease using perfluoropolyether as base oil and PTFE powder as thickener. It exhibits outstanding resistance to high‑temperature thermal decomposition and excellent inertness toward most aggressive chemical solvents and corrosive fluids. The grease maintains stable lubricating performance within‑40℃ to 260℃ temperature interval, protecting high‑temperature rolling bearings and moving components of chemical production
Product DetailsPFPE High‑Temperature Long‑Life Grease CAS 9002‑84‑0, Perfluoropolyether PTFE -40~260℃ for High‑Temp Bearing Chemical EquipmentThis fluorinated grease is formulated with high‑purity perfluoropolyether base fluid and fine‑grade PTFE thickener without hydrocarbon‑based additives. The fluorine‑rich molecular structure provides inherent thermal stability, resisting carbonization and hardening even under sustained high‑temperature exposure up to 260℃. At the low‑temperature limit of‑40℃, the grease retains appropriate fluidity and avoids excessive stiffening, enabling reliable cold start‑up of mechanical assemblies.
When applied to high‑temperature rolling and plain bearings operating inside thermal processing equipment, ovens and drying units, the grease forms a persistent lubricating film on raceways and rolling elements. It resists thermal evaporation and minimizes grease consumption, achieving extended relubrication intervals. For chemical‑processing equipment including reactor agitator bearings, valve spindles and pump shaft seals, the grease demonstrates chemical inertness against many organic solvents, acidic vapors and alkaline media. It will not dissolve or degrade upon contact with aggressive process fluids, preventing lubricant failure caused by chemical attack.
This PFPE‑PTFE grease shows very low outgassing characteristics, and maintains consistent mechanical stability under continuous shearing. It does not generate carbonaceous deposits at elevated operating temperatures, which helps to reduce abrasive contamination inside bearing housings.
It is suitable for permanent or long‑term lubrication of furnace rollers, oven conveyor bearings, chemical reactor shaft bearings and process valve moving components. The recommended coating or filling amount should be strictly controlled; over‑filling inside bearing chambers may induce excessive churning heat during high‑speed rotation.
Do not mix PFPE grease with conventional hydrocarbon‑based greases. Contamination by non‑fluorinated lubricants will severely degrade high‑temperature resistance and chemical inertness performance. Store the product in tightly sealed original containers inside cool and dry warehouse. Avoid direct sunlight and prolonged high‑temperature storage, to preserve original paste consistency for high‑temperature bearing and chemical equipment lubrication.
