NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of high-quality chemical intermediates. Among our extensive product portfolio, Polyisobutylene Succinic Anhydride (PIBSA) stands out for its critical role in the formulation of modern lubricants. Understanding the synthesis and application of PIBSA is key to appreciating its contribution to engine performance and protection.

PIBSA, with its chemical name Polyisobutylene Succinic Anhydride and CAS number 67762-77-0, is primarily derived from the reaction between polyisobutylene and maleic anhydride. This process yields a compound that possesses both a long, oil-soluble hydrocarbon chain and a reactive polar succinic anhydride group. This dual nature makes it an ideal intermediate for creating a variety of functional additives.

The primary application of PIBSA in the lubricant industry is as a precursor to ashless dispersants, such as Polyisobutylene Succinimide (PIBSI). These dispersants are essential components in engine oils, gear oils, and hydraulic fluids. Their function is to suspend contaminants like soot, sludge, and wear particles, preventing them from agglomerating and forming deposits on engine surfaces. By keeping these contaminants dispersed, PIBSA-derived dispersants contribute significantly to maintaining engine cleanliness, reducing wear, and extending the service life of the lubricant and the engine itself. We offer high-quality PIBSA for purchase, ensuring manufacturers can source reliable components for their additive packages.

The synthesis of PIBSA typically involves either a thermal addition method or a chlorination addition method. The thermal addition method, which utilizes highly active polyisobutylene (HRPIB), is increasingly preferred due to its chlorine-free nature. This eco-friendly approach aligns with industry demands for sustainable chemical manufacturing. Manufacturers seeking to buy PIBSA can inquire about its production methods to ensure compliance with environmental standards.

Beyond its role in dispersants, PIBSA also finds application in the synthesis of other lubricant additives, including rust inhibitors and emulsifiers for specific industrial uses. Its versatility underscores its importance as a foundational chemical in the additive manufacturing sector. For companies looking to buy PIBSA, NINGBO INNO PHARMCHEM CO.,LTD. provides competitive pricing and supports online purchase inquiries, ensuring a streamlined procurement process.

In conclusion, PIBSA is an indispensable intermediate for lubricant additive manufacturers. Its ability to form high-performance ashless dispersants is critical for protecting engines and ensuring optimal lubricant function. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying this vital chemical, supporting the continuous innovation and quality demands of the global lubricant market.
