What is PIBSA?
Polyisobutylene succinic anhydride (PIBSA) is one of the most important building blocks in many additives, valued for its ability to disperse, emulsify, and stabilize in a wide range of formulations. Our expertise in PIBSA manufacturing allows us to deliver consistent, customizable components that integrate smoothly into advanced formulations across industrial markets. These include emulsifiers for bulk explosives, emulsifiers for packaged explosives, emulsifiers for metalworking fluids, and upstream chemicals for oil and gas applications.
At Nelson Brothers, PIBSA sits at the core of many of our technologies, supporting the performance, reliability, and flexibility our customers expect.

PIBSA Applications by Market
- Bulk and packaged explosives: PIBSA-based emulsifiers stabilize the water-in-oil emulsions used in emulsion explosives.
- Metalworking fluids: PIBSA Additives for Metalworking and Metalworking Emulsifiers keep soluble oils and semi-synthetics stable in use.
- Oil and gas: PIBSA serves as a building block for upstream production chemicals.
- Fuel additives: reacting PIBSA with polyamines produces PIBSI, the basis of many fuel detergents and dispersants.
FAQs
What is PIBSA?
PIBSA is polyisobutylene succinic anhydride, a building block for additives that disperse, emulsify, and stabilize across many industrial formulations.
What is PIBSA used for?
PIBSA is used to make emulsifiers for bulk and packaged explosives and metalworking fluids, upstream oil and gas chemicals, and dispersants and detergents.
What is the difference between PIBSA and PIBSI?
PIBSI, polyisobutylene succinimide, is made by reacting PIBSA with polyamines. PIBSI is widely used as a dispersant and as the active ingredient in fuel detergents.
Can Nelson Brothers customize PIBSA?
Yes. We can adjust molecular weight distribution, viscosity, functionalization level, and reactivity profile to fit your formulation.
Can I get a PIBSA sample?
Yes. Request a sample and our technical team will help you select and evaluate the right PIBSA for your application.
