This fluorosilicone grease is a specialty high‑end lubricating grease based on fluorosilicone base fluid, formulated with dedicated thickener, PTFE solid filler and stabilizing anti‑oxidant additives. Its fluorine‑containing molecular structure delivers outstanding resistance to various solvents, fuels and corrosive chemical media. The grease maintains stable lubricating properties under wide extreme‑temperature range, and offers reliable lubrication and sealing protection for valve seals and fl

Product Detail

Product DetailsFluorosilicone Grease CAS 9002‑84‑0, Chemical‑Resistant Solvent‑Resistant for Valve Seal Extreme Temp FluoropolymerThis fluorosilicone grease is compounded with fluorosilicone base fluid, special thickening agent, finely dispersed PTFE filler and anti‑oxidant stabilizing additives. The fluorinated silicone backbone grants the base fluid inherent resistance against organic solvents, hydrocarbon fuels and many corrosive liquid media. The suspended PTFE solid filler forms low‑friction sliding interfaces, effectively lowering friction torque during repeated opening‑closing cycles of valve spindles. The grease maintains consistent physical consistency under extreme‑temperature fluctuations, without severe thermal softening at high temperature or excessive hardening under cold conditions.

When applied to valve stem seals, gland packing, and mating surfaces of fluoropolymer gaskets and O‑rings, the grease forms a dense, adherent lubricating‑sealing film. This thin composite film fills micro‑surface gaps of sealing elements, reducing the risk of chemical medium permeation and leakage. It alleviates stick‑slip phenomenon for valve stems during frequent actuation and mitigates abrasive wear on fluoropolymer seal parts. Good material compatibility helps avoid swelling, softening or premature degradation of fluoropolymer elastomer seals that are exposed to process fluids.

Under continuous mechanical shearing from cyclic valve operation, the grease matrix exhibits excellent shear stability and restrains oil separation. The anti‑oxidant additive system suppresses thermal‑oxidative decomposition of fluorosilicone base fluid at elevated temperatures, extending the service life of dynamic sealing points. It retains core sealing‑lubricating performance even with intermittent exposure to aggressive solvents.

It is suitable for assembly lubrication and on‑site maintenance greasing of process control valves, chemical pipeline valve stem seals, fluoropolymer gaskets and fluorine‑containing sealing assemblies. Precise control of coating thickness is required. Excessive grease may be extruded into the flowing process medium and cause contamination; insufficient coating cannot build a complete protective film, which results in increased friction torque, accelerated seal abrasion and potential medium leakage.

Do not mix this fluorosilicone grease with lithium‑based grease, ordinary silicone grease or hydrocarbon‑type lubricating greases. Incompatible blending will disrupt the thickener network, reduce solvent and chemical‑resistant capability and degrade extreme‑temperature sealing‑lubricating performance. Store in tightly sealed original containers inside cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to sustain chemical‑resistant, solvent‑resistant lubricating and sealing performance for valve seals and fluoropolymer components under extreme‑temperature working conditions.
