P-GR OT 20 N Low-Temperature PFPE PTFE Synthetic Grease

Detailed Information

- Model: P-GR OT 20 N
- Packaging: 1KG
- Key Ingredients: Perfluoropolyether, polytetrafluoroethylene, and additives.
- Type: Low-temperature PFPE grease, synthetic lubricant for rubber, PTFE grease, cold-resistant bearing grease. P-GR OT 20 N Perfluoropolyether Lubricating Grease is a low-temperature, long-lasting synthetic grease based on low-viscosity perfluoropolyether (PFPE) and polytetrafluoroethylene (PTFE). With the advantages of a low-viscosity base and a neutral formulation, it offers excellent low-temperature sliding friction performance, material compatibility, and long-term stability. It is specifically designed for lubrication at low temperatures and for rubber and plastic components, meeting the long-term lubrication needs of multi-material combinations.

Core Information

The grease uses low-viscosity perfluoropolyether oil (PFPE) as the base oil, combined with polytetrafluoroethylene (PTFE) micropowder as a thickener. The formulation is homogeneous and stable, free of redundant additives, and optimized for sliding-friction performance and material compatibility in low-temperature environments.
Appearance and Physical Properties: The grease is white, odorless, and tasteless, with a uniform texture that is easy to apply. It has an NLGI grade of 2, with a penetration (DIN ISO 2137) range of 265-295×0.1mm at 25°C. The kinematic viscosity of the base oil at 40°C is approximately 17 mm²/s, ensuring excellent low-temperature fluidity.
Temperature Adaptation Range: The grease demonstrates outstanding low-temperature adaptability, with a working temperature range from -50°C to 70°C. At -50°C, the flow pressure (DIN 51805-2) is ≤1400 mbar, ensuring reliable operation during low-temperature starts and sustained low-temperature conditions.
Key Stability Indicators:
Oil separation rate at 70°C for 30 hours (ASTM D 6184): ≤6% (by weight).
Evaporation loss at 66°C for 22 hours (ASTM D 2595): ≤2% (by weight).
Copper corrosion (DIN 51811, 100°C/24h): Corrosion grade 1-100, demonstrating excellent stability.

Key Characteristics

Leveraging the low-viscosity PFPE base and exclusive formulation, this product excels in low-temperature lubrication, friction control, and material compatibility, as detailed below:
Exceptional Low-Temperature Adaptability: Operates stably within a temperature range of -50°C to 70°C. The low-viscosity base oil combined with the optimized formulation ensures excellent fluidity at low temperatures, effectively reducing cold-start resistance and preventing stick-slip phenomena, ensuring smooth operation in low-temperature conditions.
Outstanding Friction Control: The synergy between the PTFE thickener and low-viscosity PFPE results in a low sliding friction coefficient, reducing frictional heat generation under dynamic loads in elastomers. This significantly extends the service life of rubber, plastic, and metal components.
Comprehensive Material Compatibility: Neutral to most plastics and elastomers, with no risk of swelling, aging, or damage. It has passed compatibility tests with selected non-ferrous metals, making it safe for multi-material components and suitable for a wide range of applications.
Long-Lasting Lubrication Stability: With low oil separation and evaporation loss characteristics, the grease ensures consistent performance over extended periods without frequent re-lubrication, significantly reducing maintenance frequency and equipment downtime costs.

Scope of Application

Thanks to its excellent low-temperature performance and material compatibility, this product is particularly suited for rubber and plastic components, low-temperature equipment, and precision machinery. Specific applications include:
Rubber and Plastic Components: Ideal for lubricating plastic parts and seals. Its low-friction properties reduce wear and heat generation in rubber and plastic materials, while the neutral formulation prevents material aging and deformation, extending component lifespan.
Low-Temperature Equipment: Suitable for mechanical components operating in low-temperature environments, such as refrigeration equipment and outdoor low-temperature machinery, ensuring reliable cold starts and operational stability.
Precision Machinery: Applicable to precision machinery with multi-material components, especially for precision transmission parts requiring high performance in low-temperature lubrication, material compatibility, and friction control.
Other Scenarios: Can be used for various general mechanical components requiring long-term low-temperature lubrication and low friction loss, covering industries such as automotive, electronics, and office equipment.

Packaging Specifications and Usage Instructions

Packaging Specifications: Available in various packaging sizes to meet different usage requirements.
Usage Guidelines: This product is classified as a non-hazardous chemical. Store in a sealed, dry, and cool environment, avoiding contact with impurities or highly corrosive substances to prevent contamination and maintain optimal lubrication performance. Before application, thoroughly clean the friction points to remove oil, dust, and residual grease. Use an appropriate solvent for cleaning, and ensure surfaces are dry to improve grease adhesion.
Apply directly using a brush, spatula, or lubrication dispenser. Ensure even coverage of the friction surface, avoiding over-application to prevent poor heat dissipation and reduced component efficiency.
