P-BBARRIERTA I MI-202 PFPE Extreme Temperature Grease for Sealing Protection

- Model: P-BBARRIERTA I MI-202
- Packaging: 1KG
- Key Ingredients: Perfluoropolyether, polytetrafluoroethylene, and additives.

- Type: Extreme temperature grease, PTFE low friction precision lubrication grease, corrosion-resistant fluorinated grease for strong acids and alkalis, sealing protection high-performance PFPE grease. P-BBARRIERTA I MI-202 is a specially developed perfluoropolyether (PFPE)-based high-performance grease, designed to provide long-lasting lubrication and comprehensive protection for precision mechanical components operating under extreme temperature fluctuations, strong chemical corrosion, and high sealing requirements for lubrication films.

- Extreme Temperature Stability: Leveraging the unique molecular structure of PFPE base oil and the synergistic effects of the modified PTFE thickener, P-BBARRIERTA I MI-202 maintains low viscosity even in -40°C environments, ensuring smooth mechanical start-up without jamming. At +280°C, the lubrication film resists decomposition and loss, continuously protecting components and addressing the common issues of"low-temperature thickening and high-temperature failure"seen with conventional greases.
- Superior Corrosion Resistance and Sealing Protection: This product offers exceptional resistance to strong acids (such as nitric acid and phosphoric acid, concentration ≤50%), strong alkalis (such as potassium hydroxide solution, concentration ≤50%), strong oxidizing agents (such as hydrogen peroxide), and various organic solvents (such as methanol, ether, and xylene). The lubrication film remains structurally intact upon contact with these media, effectively isolating them from metal components to prevent corrosion and rust. Additionally, its excellent colloidal stability ensures no oil separation or soap precipitation during long-term use. It tightly fills component gaps, forming a reliable auxiliary sealing layer that blocks the intrusion of dust, impurities, and liquid media.
- Low Friction and Material Compatibility: The nano-scale particles of the modified PTFE thickener form a uniform and dense lubrication film on surfaces made of metal, ceramics, and other materials. The friction coefficient of steel-to-steel friction pairs can be reduced to as low as 0.06-0.09, significantly lower than that of ordinary fluorinated greases, thereby reducing component wear and tear. Moreover, the product exhibits excellent compatibility with most engineering plastics (e.g., PTFE, polyimide), rubbers (e.g., nitrile rubber, fluororubber), and metal materials. It does not cause swelling, shrinkage, or embrittlement, making it suitable for a wide range of material combinations in mechanical components.

Given its outstanding comprehensive performance, P-BBARRIERTA I MI-202 is particularly suited for the lubrication of precision components in extreme environments. In the chemical industry, it is ideal for sealing bearings in reactor stirrer shafts and acid/alkali transfer pump bearings, capable of withstanding strong corrosive media and temperature fluctuations. In the semiconductor manufacturing sector, it is used for precision guides in wafer etching equipment and vacuum valve bearings, meeting requirements for high cleanliness, a wide temperature range, and plasma corrosion resistance. In the food processing industry, it is suitable for high-temperature baking equipment transmission bearings and sealing components in sterilization equipment, compliant with food contact safety standards. In the aerospace sector, it applies to auxiliary component bearings in aircraft engines and lubrication points in spacecraft attitude adjustment mechanisms, addressing extreme temperature variations and radiation in space. Furthermore, it can be used in the new energy industry for sealing components in fuel cell stacks and high-temperature heat pump compressor bearings, ensuring stable operation of equipment under demanding conditions.
