Teflono ThermoMax
Premium high-temperature PTFE grease for continuous operation at 250-280°C
ThermoMax is engineered for sustained high-temperature service in industrial ovens, kilns, and furnace conveyor systems. Its advanced PTFE micro-particle dispersion in a PAO synthetic base oil ensures consistent lubrication even as temperatures approach 280°C. The lithium complex thickener provides excellent mechanical stability and water resistance, while anti-oxidant and anti-wear additives extend both grease and equipment life significantly.

Process Steps
Base Oil Preparation
Heat PAO 40 base oil in a stainless steel mixing vessel. Use a thermocouple to monitor temperature. Ensure the vessel is clean and dry before starting.
Thickener Dispersion
Slowly add lithium complex thickener to the heated oil while stirring at 500-800 RPM. Add 12-hydroxystearic acid simultaneously to ensure even dispersion. Avoid clumping by adding in small increments.
High-Temperature Cook
Increase temperature to initiate saponification reaction. Maintain constant stirring. The mixture will thicken and become translucent. Hold at peak temperature for the specified duration.
Controlled Cooling & PTFE Addition
Begin controlled cooling. When temperature reaches 150°C, slowly sift in PTFE micro-powder while maintaining 1000+ RPM agitation to prevent agglomeration. The PTFE must be evenly dispersed throughout.
Additive Blending
At 120°C, add anti-oxidant (DPPD), anti-wear (ZDDP), corrosion inhibitor, viscosity modifier, and anti-foam agent in sequence. Stir each additive for 3 minutes before adding the next.
Milling & Homogenization
Pass the cooled grease through a three-roll mill 3 times at progressively tighter gaps (0.05mm, 0.03mm, 0.01mm) to break down any remaining particle clusters and ensure smooth, consistent texture.
Quality Testing & Packaging
Perform cone penetration test (NLGI Grade 2: 265-295 dmm), drop point verification (>280°C), and visual inspection. Package in clean, dry containers with minimal headspace to prevent oxidation.
Required Equipment
- Stainless steel mixing vessel (2L capacity min)
- Variable speed agitator (100-1500 RPM)
- Thermocouple with digital readout
- Heating mantle or oil bath
- Three-roll mill or colloid mill
- Analytical balance (0.1g precision)
- Cone penetrometer
- Drop point apparatus
- PPE: heat-resistant gloves, safety goggles, lab coat
Safety Notes
- PTFE powder is non-toxic but may cause irritation if inhaled - use dust mask during handling
- Temperatures exceed 200°C during cook stage - use heat-resistant gloves and face shield
- ZDDP contains zinc compounds - handle with care, avoid skin contact
- Ensure adequate ventilation throughout the manufacturing process
- Keep fire extinguisher nearby - PAO oil is combustible at elevated temperatures
- Allow grease to cool below 60°C before handling for packaging
Quality Control Checks
- Cone penetration: 265-295 dmm (ASTM D217)
- Drop point: >280°C (ASTM D2265)
- Four-ball wear scar: <0.5 mm (ASTM D2266)
- Water washout: <3% (ASTM D1264)
- Copper strip corrosion: 1a (ASTM D4048)
- Visual: Smooth, homogeneous texture with no lumps or separation
