P-BBARRIERTA GTE 403 PFPE Extreme Temperature Grease for Vacuum and Aerospace

- Model: P-BBARRIERTA GTE 403
- Packaging: 1KG
- Key Ingredients: Perfluoropolyether, polytetrafluoroethylene, and additives.

- Type: Perfluoropolyether grease, extreme temperature grease, high-temperature lubrication, PTFE thickener vacuum grease, aerospace industrial grease. P-BBARRIERTA GTE 403 perfluoropolyether (PFPE) grease is specifically designed for extreme operating conditions and is one of the core products of the BARRIERTA series. It uses high-purity perfluoropolyether oil as the base oil, combined with ultra-fine polytetrafluoroethylene (PTFE) thickener. The base oil content is significantly higher compared to similar products, providing a solid foundation for long-lasting lubrication.

(1) Adaptability to Extreme Environments
- Stable operation across a wide temperature range: Operates within a temperature range of -40℃ to 240℃, withstanding higher peak temperatures for short durations. It is also suitable for high-vacuum and ultra-high-vacuum environments, addressing industry challenges such as high-temperature volatilization and low-temperature solidification.
- Comprehensive resistance: Exhibits excellent resistance to water and chemical corrosion, capable of withstanding harsh media such as acids, alkalis, and solvents. It is non-flammable, has extremely low evaporation rates, and its high-temperature stability has been validated across multiple industries over extended periods.
(2) Long-lasting Protection and Compatibility
- Extends equipment lifespan: The synergistic effect of PTFE thickener and high-content base oil forms a durable lubrication film on rolling bearings and sliding components, significantly extending lubrication intervals and reducing maintenance costs.
- Material compatibility: Chemically neutral to elastomers such as nitrile rubber and fluororubber, as well as engineering plastics like PA and POM. It poses no risks of swelling or embrittlement and forms a dense protective film on metal surfaces, protecting against moisture and salt spray corrosion.

- Industrial Manufacturing: Lubrication for metallurgical kiln bearings, semiconductor equipment seals, and rotary kiln components in the cement industry, adapted to high-temperature and dusty environments.
- High-End Equipment: Vacuum devices in aerospace, sliding components of precision electronic instruments, leveraging low volatility characteristics to ensure equipment accuracy.
- Specialized Industries: Equipment for food processing and cosmetics production (NSF certification required for specific batches), meeting stringent hygiene requirements.
