Polyisobutylene Succinic Anhydride (PIBSA) is a high-performance intermediate used to produce advanced lubricant additives. Derived from high reactive polyisobutylene (Mn=1000) through the thermal adduction process, PIBSA plays a critical role in enhancing the efficiency and longevity of lubricants across various applications.

Key Properties

1. Exceptional Detergency

   • Acts as a precursor to ashless dispersants that prevent sludge, varnish, and deposit formation in engines.

2. Low-Temperature Performance

   • Improves sludge dispersion even in low-temperature conditions, ensuring reliable operation in demanding environments.

3. Versatile Application

   • Functions as a base material for producing detergents, dispersants, and other performance-enhancing lubricant additives.

4. Chlorine-Free

   • Environmentally friendly with no chlorine content, supporting sustainable formulations.

Applications

Polyisobutylene Succinic Anhydride is a fundamental ingredient in various industrial and automotive applications, including:

1. Lubricant Additive Production

   • Ashless Dispersants: Enhances oil cleanliness by dispersing contaminants like soot, sludge, and varnish particles.
   • Detergents: Contributes to maintaining engine cleanliness by preventing deposit formation.

2. Viscosity Index Improvers

   • Stabilizes lubricant viscosity across a wide temperature range, improving performance in extreme conditions.

3. Emulsifying Agents

   • Utilized in emulsion explosives and other industrial formulations.

4. Processing Aids

   • Supports operations in petroleum chemical plants by enhancing the efficiency of chemical processing.

Performance Benefits

1. Engine Cleanliness

   • Facilitates the creation of additives that prevent the accumulation of harmful deposits, ensuring smoother engine performance.

2. Wear Protection

   • Reduces friction and wear on metal surfaces by keeping contaminants suspended in the lubricant.

3. Enhanced Lubricant Life

   • By maintaining oil cleanliness, PIBSA-derived additives help extend oil drain intervals and improve overall cost-effectiveness.

4. Friction Reduction

   • Cleaner lubricants contribute to reduced mechanical friction, potentially improving fuel efficiency.

5. Thermal and Oxidative Stability

   • Ensures reliable lubricant performance even under high operating temperatures and extended service intervals.
