Oil & Gas Emulsifiers

PIBSA Specialty Additives

For Oil and Gas Process Additive Formulations, polyisobutylene succinic anhydride (PIBSA) is a significant precursor to manufacturing emulsifiers, detergents, and dispersant additives. Nelson Brothers works with a range of molecular weight polyisobutylene (PIB), from 450 to 2300, to manufacture PIBSA based additives. This molecular weight range is selected to provide the properties necessary to provide the best performance for various applications, including emulsifiers for drilling fluids, detergents for controlling fouling, and dispersants for coke and asphaltene deposition control.

Nelson Brothers PIBSA is produced via the thermal process using highly reactive (HR) polyisobutylene (PIB). As a result of this process, there is no residual chlorine present. Nelson Brothers products are predominantly produced from highly reactive polyisobutylene (HR PIB), however, products based on conventional polyisobutylene can also be produced if required by the customer.

Nelson Brothers is advantageously positioned for the custom manufacture of succinic anhydride and related derivatives. As a well-established PIBSA manufacturer, we have developed a broad base of capabilities to meet a wide range of applications.

Nelson Brothers Specialty Chemicals offers laboratory-size samples of products to prospective customers free of charge.

Available in 5 standard molecular weights 

 Available as concentrates or blends
