Product Description

Ethylene-enriched lubricant additive

Ethylene-enriched lubricant additive combines 10% HA0501 specialty polymer with 90% 150SN base oil, engineered to deliver optimized viscosity performance and mechanical protection in moderate-to-severe operating conditions. The high ethylene content enables superior thermal stability while maintaining critical lubricating properties.

Key Characteristics

High Ethylene Backbone (49%)
Enhances polymer elasticity for improved film strength
Boosts oxidative resistance at sustained high temperatures
Controlled Shear Performance
SSI: 21% (Diesel injector, 30 cycles)
Typical for moderate-SSI applications where viscosity stability remains within operational limits
Targeted Viscosity Profile
Kinematic Viscosity: 850 mm²/s @100°C
Ideal for industrial/automotive systems requiring ISO VG 800-1000 grade fluids
Premium Base Oil Synergy
90% 150SN base oil ensures optimal additive solubility and pumpability

Recommended Applications

Industrial gearboxes (ISO VG 680-1000)
Hydraulic systems operating at ≤90°C
Mid-range diesel engines without extended drain intervals
Compressor oils requiring oxidation-stable base stocks
