The same chemistry trusted in jet engine bearings, satellite mechanisms, and high-vacuum aerospace applications — engineered for the most demanding RC racing applications. PFPE is unlike any other lubricant chemistry. Once you understand why, you'll never go back.
PFPE — perfluoropolyether — is a class of synthetic lubricants developed for applications where conventional oils and greases fail. We're talking jet engine bearings spinning at 30,000+ RPM, satellite mechanisms exposed to vacuum and radiation, semiconductor manufacturing, and chemical processing where reactivity is unacceptable.
Why? Because PFPE doesn't oxidize, doesn't break down under extreme heat, doesn't react chemically with anything, and maintains its viscosity across enormous temperature ranges. Where mineral oils smoke and synthetic greases gum up, PFPE keeps working.
The Heliox line brings this aerospace-grade chemistry to RC racing. Specifically formulated for the most demanding applications — high-RPM ceramic bearings, high-load drivetrain components, and severe-duty conditions where conventional lubricants compromise.
Six properties that set PFPE apart from every other lubricant chemistry — and why they matter for elite RC racing.
PFPE doesn't react with metals, plastics, oxygen, or fuels. It stays exactly what it was when you applied it — for the entire life of the lubricant.
Functional from -70°C to +250°C without viscosity collapse. RC racing heat — even ceramic bearing temps — is well within PFPE's comfort zone.
Conventional oils oxidize, thicken, and form deposits over time. PFPE doesn't oxidize at all. The viscosity you applied is the viscosity you keep.
PFPE bonds to metal surfaces at the molecular level, providing protection under extreme pressure that conventional EP additives cannot match.
Unlike hydrocarbon lubricants, PFPE is non-flammable. Critical for high-RPM applications where lubricant atomization could otherwise be a fire risk.
PFPE doesn't break down, oxidize, or wash out. Apply once, perform consistently. Real-world service life can be 10x conventional lubricants.
Each Heliox product applies PFPE chemistry to a specific RC racing application. The complete system, engineered together.

PFPE base stocks are significantly more expensive than conventional lubricant chemistry — that's why aerospace specifies them only where their performance justifies the cost. The Heliox line is premium-priced because aerospace-grade chemistry is premium-cost. For your most demanding components, it's the right investment.
