XYC GREASE 90 Oxygen-Safe PCTFE Fluorinated Grease BAM-Approved for Valves and Seals 1KG
Basic Information
- Product Profile: XYC GREASE 90
- XYC GREASE 90
- Characteristics: Oxygen-compatible grease, PCTFE fluorinated grease, high-temperature oxygen grease, chemical-resistant valve grease, BAM-approved grease.
- XYC Grease 90 is a high-temperature, chemically inert synthetic fluorinated grease manufactured by XiaoYiChong. It is formulated from a blend of low-molecular-weight polychlorotrifluoroethylene (PCTFE) base oils thickened with an inorganic silica gelling agent. It is designed specifically for valves, taps, seals, and bearings operating in aggressive chemical environments, high-pressure oxygen service, or radioactive conditions.

Core Performance Advantages
- Oxygen & Reactive Gas Safety: Fully safe for high-pressure gaseous and liquid oxygen (GOX/LOX) service. It will not ignite, burn, or react in oxygen-rich environments.
- Radiation Resistance: Demonstrates high stability and resistance to breakdown when exposed to X-rays and gamma radiation (making it ideal for nuclear facilities).
- Chemical & Water Washout Resistance: Resists degradation from steam, water, and many aggressive chemical reagents, maintaining its lubricating film.
- Non-Melting Structure: The inorganic silica gel structure prevents the grease from melting or dripping at elevated temperatures up to 170℃.
- Radiation Resistance: Demonstrates high stability and resistance to breakdown when exposed to X-rays and gamma radiation (making it ideal for nuclear facilities).
- Chemical & Water Washout Resistance: Resists degradation from steam, water, and many aggressive chemical reagents, maintaining its lubricating film.
- Non-Melting Structure: The inorganic silica gel structure prevents the grease from melting or dripping at elevated temperatures up to 170℃.
Important Chemical Incompatibility Warning
Chemical Avoidance Notice: Because XYC Grease 90 relies on an amorphous silica thickener, it must NOT be used in applications exposed to:
Primary Applications
1. Oxygen Plant Equipment: Lubrication and sealing of valves, taps, regulators, and fittings handling gaseous or liquid oxygen.
2. Nuclear Facilities: Valve stems, actuators, and mechanical joints subject to radiation and thermal exposure.
3. Chemical Processing: Taps, flow meters, and ball/plug valves operating with aggressive non-alkaline gases and acids.

Chemical Resistance Differences
The choice between XYC Grease 90 and XYC Grease 901 usually comes down to the specific chemical media in your process:
- XYC Grease 90 (Silica Thickener):
- Excellent resistance to neutral gases, dry chlorine, strong mineral acids, water, and steam.
- Critical Limitation: Because it is thickened with silica, XYC Grease 90 is attacked and dissolved by Hydrofluoric Acid (HF) and concentrated alkaline solutions (e.g., liquid NaOH or KOH).
- XYC Grease 901 (Silica-Free / Fluoropolymer Thickener):
- Provides total chemical inertness across a broader spectrum.
- Resists concentrated alkalis, strong bases, hydrofluoric acid, halogens, organic solvents, and aggressive oxidizers without degradation or washout.
- Excellent resistance to neutral gases, dry chlorine, strong mineral acids, water, and steam.
- Critical Limitation: Because it is thickened with silica, XYC Grease 90 is attacked and dissolved by Hydrofluoric Acid (HF) and concentrated alkaline solutions (e.g., liquid NaOH or KOH).
- XYC Grease 901 (Silica-Free / Fluoropolymer Thickener):
- Provides total chemical inertness across a broader spectrum.
- Resists concentrated alkalis, strong bases, hydrofluoric acid, halogens, organic solvents, and aggressive oxidizers without degradation or washout.
Typical Applications Difference
XYC Grease 90
- High-temperature valve stems and regulators (150℃ to 170℃).
- Oxygen compression and transfer equipment in non-alkaline environments.
- Equipment exposed to radiation in nuclear facilities (due to strong radiation resistance).
XYC Grease 901
- Chemical plant valves, pumps, and seals handling caustic liquids/alkalis or hydrofluoric acid.
- Assembly lubricant for fluoropolymer (PTFE/FKM) seals, gaskets, and O-rings exposed to harsh solvents or acid lines.
- Low-temperature chemical service down to -20℃.
- High-temperature valve stems and regulators (150℃ to 170℃).
