Product Details
Chemost supplies premium PIBSA polyisobutylene succinic anhydride to B2B buyers and additive blending plants worldwide.
Product Description
Polyisobutylene succinic anhydride (PIBSA) is made through the thermal process using high activity polyisobutylene as raw material, reacting with MA.
Polyisobutylene succinic anhydride (PIBSA) characteristics include no residual chlorine content, no impact on emulsifying properties, and residual maleic anhydride below 0.5%.
CheMost production facility utilizes an advanced thermal process, ensuring that the final product contains absolutely no chlorine and yields very few by-products.
Pibsa cas number 68412-26-0
Polyisobutylene succinic anhydride serves as an essential pibsa for lubricant additives and fuel additives, tackiness agent, and emulsifier of emulsion explosive. Furthermore, our factory can customize the viscosity and acid value according to specific client requirements.

FTIR of CheMost-PIBSA
Primary Applications
- Lubricant Additives: Improves dispersancy and cleanliness. Precursor for PIBSI dispersants. Typical dosage is 0.5 to 3 percent depending on the system.
- Fuel Additives: Acts as an intermediate for polymeric dispersants and detergents. Please validate in your specific formulation and engine tests.
- Emulsifier of Emulsion Explosive: Acts as a highly efficient surfactant and primary emulsifier for creating stable bulk ANFO explosive matrixes.
- Tackiness Agent: Functions as a highly effective tackiness agent in various specialized industrial formulations.
Packaging and Storage Guidelines
To accommodate different factory scales, we offer flexible packaging options including 170KG per Metal drum, 900KG per IBC TANK, and bulk ISO TANK deliveries. The product should be stored in a dry, clean, and well ventilated warehouse.
Strict temperature control is advised to maintain product integrity. The maximum storage temperature is 50 °C, while the maximum blending temperature should not exceed 70 °C. When stored under proper ambient temperature conditions, the shelf life is guaranteed for 36 months.
Synonyms, Specifications & Market Terms
In the global chemical procurement network, this versatile additive is recognized by multiple technical designations. We supply high quality materials for buyers searching for any of the following specifications.
Pibsa full form / pibsa chemical formula
The pibsa full form is Polyisobutylene Succinic Anhydride. Due to its polymeric nature, the exact pibsa chemical formula varies based on the chain length of the polyisobutylene tail, typically represented as a succinic anhydride ring attached to a long hydrocarbon chain.
Pibsa structure
The pibsa structure features a highly polar succinic anhydride head group bonded to a non polar, lipophilic polyisobutylene tail. This unique amphiphilic architecture is the foundation of its exceptional emulsifying and dispersing capabilities.
Pibsa manufacturing process / pibsa synthesis
Our pibsa manufacturing process utilizes a state of the art thermal adduction method. This pibsa synthesis involves reacting highly reactive polyisobutylene directly with maleic anhydride under controlled high temperatures, completely bypassing the traditional, environmentally harmful chlorination route.
Pibsa 1000 & pibsa 1300
These terms denote the approximate molecular weight of the polyisobutylene precursor used. We manufacture both pibsa 1000 and pibsa 1300 variants to provide formulators with the exact balance of oil solubility and polar interaction required for their specific fluid dynamic needs.
Pibsa emulsifier & pibsa dispersant
In the mining sector, it acts as an indispensable pibsa emulsifier for creating stable explosive matrixes. In the lubrication sector, it is the primary building block for creating a pibsa dispersant, which keeps engine soot and sludge suspended in the oil.
Pibsa uses & pibsa manufacturers
The primary pibsa uses span across manufacturing ashless dispersants, creating robust ANFO emulsions, and acting as a rust inhibitor in metalworking fluids. As one of the premier pibsa manufacturers, Chemost guarantees a secure supply chain and strict batch consistency for all these applications.
Frequently Asked Questions FAQ
Q:What is PIBSA used for?
A:It is primarily used as a highly active chemical intermediate. Its applications include acting as an emulsifier of emulsion explosive for the mining industry, serving as a tackiness agent, and functioning as a precursor for lubricant additives and fuel additives.
Q:How to make PIBSA?
A:It is made through the thermal process using high-activity polyisobutylene as raw material, reacting with MA. This method utilizes high temperatures to drive the reaction without the use of chlorine gas, resulting in a purer, halogen free product with residual maleic anhydride below 0.5%.
Q:What is PIBSI?
A:PIBSI stands for Polyisobutylene Succinimide. It is the direct downstream product of PIBSA. Chemical manufacturers react PIBSA with various polyamines to create PIBSI, which is a widely used ashless dispersant designed to keep engine sludge and soot safely suspended in the oil.
