Product Description

HA533/150SN Additive Package

HA533/150SN High-performance lubricant additive package combines 14% HA533 polymeric additive with 86% 150SN base oil, engineered to deliver exceptional protection under extreme pressure and temperature conditions. Its advanced formulation ensures superior viscosity retention, minimal volatility, and extended equipment service life for heavy-duty industrial and automotive applications.

This product is an hydrogenated styrene-isoprene copolymer, with a block appearance. It is a ideal viscosity index improver. It has particularly good shear resistance and the ability to increase the viscosity index. Compared to OCP-type VII, it has a minimal impact on the CCS of the oil.

Key Features & Technical Advantages

Extreme Shear Stability
SSI (Shear Stability Index): 5% (Diesel injector nozzle, 30 cycles)
Maintains viscosity integrity under high-stress operation, preventing mechanical wear.
Ultra-High Temperature Performance
Kinematic Viscosity: 1000 mm²/s @100°C
Volatility: 1.20% – Minimizes oil loss at elevated temperatures.
Advanced Molecular Design
Narrow Molecular Weight Distribution: Optimizes flow properties & load-bearing capacity.
Ash Content: 0.1% – Compatible with exhaust after-treatment systems (DPF/SCR).
Cost-Effective Formulation
Synergistic blend of HA533 additive + 150SN base oil (14:86 ratio) balances performance and economy.

Target Applications

Heavy-duty diesel engines (turbochargers, crankcases)
High-temperature industrial gearboxes & hydraulic systems
Equipment requiring extended oil drain intervals
