Heavy Alkyl Benzene (H68)

• Viscosity @ 40℃: 61.2 - 74.8 mm²/s (ISO VG 68 Range) 

• Viscosity @ 100℃: 6 - 10 mm²/s

• Flash Point (Open Cup): ≥ 200℃ (Safe for High Temp)

• Pour Point: ≤ -40℃ (Superior Cold Flow)

• Density @ 20℃: 0.855 - 0.885 g/cm³

• Distillation Range: 350℃ - 500℃

The industry-standard synthetic base oil for thermal and lubrication systems:

• Refrigeration Compressors (Primary Use): A drop-in synthetic base oil for ammonia (R717) and HCFC (R22) refrigeration systems. H68 offers excellent low-temperature fluidity (-40℃ Pour Point) and chemical stability, preventing wax precipitation in evaporator coils.

• Heat Transfer Fluids (Thermic Fluids): Used as a heat transfer medium in closed-loop systems (-30℃ to 300℃). It resists thermal cracking better than mineral oils.

• Specialty Lubricants: Base stock for air compressor oils, hydraulic fluids, and textile machinery lubricants where thermal oxidative stability is critical.

• Electrical Industry: Impregnant for solid cables and capacitors due to high dielectric strength and gas-absorbing properties.
