HA161B Boronized High Molecular Polyisobutene Bis-Succinimide

HA161B Boronized High Molecular Polyisobutene Bis-Succinimide has superior high-temperature cleanliness and oxidation resistance. After the combination of boron and high-molecular-weight polyisobutylene (Mn≥2000), a more stable boron-nitrogen heterocyclic structure is formed, which can withstand extreme high temperatures (such as over 350℃)

Product Description

CAS: 84605-20-9
Molecular formula: R-C4H3O2NB(C2H4NH)m C2H4 C4H3O2-R

HA161B Boronized High Molecular Polyisobutene Bis-Succinimide has superior high-temperature cleanliness and oxidation resistance. After the combination of boron and high-molecular-weight polyisobutylene (Mn≥2000), a more stable boron-nitrogen heterocyclic structure is formed, which can withstand extreme high temperatures (such as over 350℃), inhibit carbon deposits in the piston top ring groove and varnish formation, and significantly delay oil oxidation (the oxidation induction period is extended by more than 50%). The boron structure endows it with anti-wear properties (the wear scar diameter in the four-ball test is reduced by 15%-20%), reducing metal surface wear while dispersing soot, and is especially suitable for high-soot content diesel engine oil (such as API CK-4/SP grade). It contains no harmful elements such as chlorine and sulfur, meets low ash (SAPS) and low emission requirements (such as Euro VII, China VI standards), and has better compatibility with fluororubber and silicone rubber sealing materials (the swelling rate is reduced by 30%). The high-molecular-weight segments enhance oil solubility, reduce high-temperature volatility (NOACK loss ≤6%), and improve oil-water separation efficiency, making it suitable for marine oils and industrial lubrication in humid conditions.

APPLICATIONS

Resolves low-temperature sludge and high-temperature deposits in mixed engine oils caused by frequent starts and stops.
Controls DPF ash accumulation in diesel engine oils, extending the life of aftertreatment systems.
Inhibits extremely high-temperature deposits caused by methane combustion in gas engine oils.
Maintains lubrication stability in electric vehicle transmission fluids under high-speed, high-torque conditions.
Hydrogen fuel cell compressor lubricant: Meets anti-wear requirements in high-pressure hydrogen environments.
Wind turbine gearbox oil: Resolves sludge issues during high-load, long-cycle operation.
Aerospace hydraulic fluid: Maintains performance stability in extreme temperatures (-50°C to 200°C).
