FAQ
Expert guidance and resources to help you find the right solution.
What are PPE lubricants and why are they better than PFAS-based fluids?
PPE (Polyphenyl Ether) lubricants are high-performance synthetic fluids engineered for extreme environments where conventional or PFAS-based lubricants fail. They deliver exceptional thermal stability at temperatures exceeding 450°C, extremely low volatility, and strong resistance to chemical and radiation exposure — without the environmental and regulatory risks associated with PFAS compounds. As PFAS bans expand across industries and regions, PPE fluids offer a proven, compliant alternative that doesn't compromise performance.
Are SantoLubes products approved PFAS alternatives for aerospace and industrial applications?
Yes. SantoLubes PPE-based products are used as direct PFAS replacements across aerospace, defense, electronics, and industrial applications. Certain products meet U.S. Air Force military specification MIL-L-87100, and SantoLubes is ISO 9001:2015 certified. Major OEMs have approved SantoLubes lubricants across multiple industries, making them a trusted, regulation-ready substitute for PFAS-containing fluids.
What is the best vacuum pump fluid for ultra-high vacuum diffusion pumps?
SantoVac® 5 PPE is widely regarded as the top-performing vacuum diffusion pump fluid available. It safely produces an ultra-high vacuum of 5 x 10⁻¹⁰ torr or greater at 25°C and is recognized for its reliability, efficiency, and economy. For applications requiring contamination-free environments, SantoVac® 5P Ultra offers an advanced high-purity formulation with extremely low back-streaming characteristics. Both are PPE-based and PFAS-compliant.
What is ACCL and how does it protect electronic connectors?
ACCL (Anticorrosion Connector Lubricant) is a PPE-based lubricant designed to protect electrical contacts against corrosion, insertion damage, and fretting — without interfering with electrical conductivity. ACCL products form a stable, non-spreading film of 15–20 microns on connector surfaces, providing decades of protection even in aggressive environments. They're certified to Telcordia requirements (GR-78, GR-357, GR-121) and specified by major OEMs across telecom, automotive, aerospace, and instrumentation applications.
Which SantoLubes products are approved for food-grade applications?
SantoTrac® 50 and SantoTrac® 332-FG carry H1 credentials, making them acceptable for use as lubricants with incidental food contact in and around food processing and manufacturing equipment. These traction fluids deliver high performance — including excellent antiwear, oxidation stability, and rust and corrosion protection — while meeting food safety compliance standards.
Can SantoLubes fluids handle radiation and extreme chemical environments?
Yes. SantoVac® PPE fluids are specifically engineered to resist both ionizing radiation and aggressive chemical exposure. This makes them the lubricant of choice for nuclear, aerospace, and high-energy physics applications where standard synthetic fluids would degrade. The same chemical inertness that makes PPE fluids radiation-resistant also contributes to their long service life in chemically harsh industrial environments.
Does SantoLubes offer custom lubricant manufacturing or tolling services?
Yes. Through its affiliate SantoTolling, SantoLubes offers custom tolling and manufacturing services for specialty lubricants and synthetic fluids. This allows customers with unique formulation requirements to leverage SantoLubes' chemistry expertise and ISO 9001:2015-certified manufacturing processes. Contact the SantoLubes team directly to discuss custom formulation, private-label, or tolling arrangements.
