Teflono TitanHeat
Heavy-duty PFPE/PTFE grease with extreme load capacity for 265–295°C environments
TitanHeat combines a full perfluoropolyether (PFPE) base oil with a high-concentration sub-micron PTFE dispersion for environments demanding both extreme temperature resistance and heavy load carrying capacity. The polyurea thickener eliminates metallic soap limitations, offering exceptional shear stability with a drop point exceeding 325°C. A cerium-oxide nano-catalyst antioxidant system delivers superior oxidation stability that surpasses Krytox-class greases. Hydrophobic fumed silica provides very good water resistance. Designed for steel mill bearings, cement kiln applications, and heavy industrial equipment operating at sustained high temperatures.

Process Steps
PFPE Oil Heating
Heat PFPE base oil (Fomblin Y) in a chemically inert vessel (PTFE-lined or glass). PFPE oils require careful handling — use only fluoropolymer-compatible seals and gaskets. Maintain nitrogen blanket throughout.
Polyurea Synthesis
Dissolve octadecylamine in half the PFPE oil at 70°C. Separately, dissolve MDI in the remaining PFPE oil at 50°C. Slowly combine the two solutions under vigorous agitation (1200 RPM). Exothermic reaction will occur — monitor temperature carefully.
Thermal Treatment
Heat the polyurea-PFPE mixture to drive the reaction to completion and develop the thickener structure. This step ensures the drop point exceeds 325°C. Maintain constant stirring. The mixture should develop a smooth, creamy consistency.
PTFE, MoS₂ & hBN Incorporation
Cool to 140°C. Pre-blend sub-micron PTFE (1μm), MoS₂, and hBN in a dry container. Add the dry blend slowly to the grease while agitating at 1500+ RPM. Then add hydrophobic fumed silica for water resistance. Continue mixing until fully homogeneous.
CeO₂ Nano-catalyst & Additive Addition
Cool to 110°C. Add cerium oxide nano-catalyst first — disperse at 1000 RPM for 5 minutes. CeO₂ provides regenerative antioxidant action for superior oxidation stability. Then add phenothiazine synergist, EP additive, copper passivator, and anti-foam agent.
Milling & Deaeration
Pass through a three-roll mill at tight clearances (0.02mm final gap) for ultra-smooth texture. Then deaerate under mild vacuum (500 mbar) for 15 minutes to remove trapped air.
Testing & Packaging
Perform full QC testing: penetration (265–295 dmm), drop point (>325°C), four-ball wear (<0.35 mm), oxidation stability (>480 min at 200°C — exceeds Krytox benchmark), and EP weld point (>350 kgf). Package in steel containers with nitrogen blanket.
Required Equipment
- PTFE-lined or glass-lined mixing vessel (2L)
- High-shear mixer (up to 1500+ RPM)
- Temperature controller with thermocouple
- Three-roll mill with adjustable gap
- Vacuum deaeration system
- Nitrogen gas supply for blanketing
- Analytical balance (0.01g precision)
- Oxidation stability bomb (ASTM D942)
- Full PPE: chemical-resistant gloves, respirator, face shield
Safety Notes
- MDI is a sensitizer and respiratory hazard — use in fume hood with appropriate respirator
- PFPE oils can decompose above 340°C releasing toxic fluorine compounds — do not overheat
- CeO₂ nano-particles are an inhalation hazard — handle in enclosed systems or fume hood
- MoS₂ dust is irritating — handle in well-ventilated area with dust mask
- Exothermic polyurea reaction requires careful temperature monitoring
- Keep water away from MDI — reacts violently with moisture
- Dispose of waste chemicals according to local hazardous waste regulations
Quality Control Checks
- Cone penetration: 265–295 dmm (ASTM D217)
