Product Details
PIBSA 1000 (Polyisobutylene Succinic Anhydride)
High-Reactivity Intermediate for Performance Additives & Emulsifiers
Product Overview
Chemost’s PIBSA 1000 is a high-quality Polyisobutylene Succinic Anhydride produced via the thermal adduct process using highly reactive polyisobutylene (HR-PIB) with a molecular weight of approximately 1000.
As a versatile chemical intermediate, PIBSA 1000 serves as the "backbone" for a wide range of oil-soluble functional additives. Because it is manufactured without the use of chlorine, it offers superior thermal stability and environmental compliance, making it the preferred choice for formulating modern engine oils and industrial lubricants.
Key Features & Technical Benefits
High Reactivity: Produced from high-vinylidene PIB, ensuring a high conversion rate and high active matter content in finished derivatives.
Chlorine-Free (Thermal Process): Unlike the chlorination route, our thermal process ensures negligible chlorine content, reducing engine corrosion and meeting strict environmental regulations.
Excellent Oil Solubility: The 1000 MW polyisobutylene chain provides a perfect balance between oil solubility and the viscosity-index performance of the final derivative.
Superior Color Stability: Advanced vacuum stripping ensures a light-colored product, ideal for maintaining the aesthetic quality of premium lubricant blends.
Versatile Chemical Intermediate: Readily reacts with various amines, alcohols, or metal hydroxides to form dispersants, detergents, and emulsifiers.

Primary Applications
Ashless Dispersants: The primary raw material for producing PIB Succinimides (PIBSI) used in gasoline and diesel engine oils.
Emulsion Explosives: Acts as a high-performance emulsifier base for civilian explosives (W/O emulsions).
Corrosion Inhibitors: Reacted with specific amines to form rust preventatives for metalworking fluids and greases.
Fuel Additives: Used in the synthesis of gasoline detergents to prevent intake valve deposits.
Drilling Fluids: Serves as a surfactant component in oil-based drilling muds for the oil and gas industry.
Packaging & Storage
Packaging: Supplied in 200L metal drums, 1000L IBC tanks, or ISO tanks for bulk orders.
Storage: Store in a cool, dry, and well-ventilated warehouse. PIBSA is hygroscopic; keep containers tightly sealed to prevent moisture absorption and hydrolysis.
Handling Temperature: For ease of pumping and blending, it is recommended to heat the product to 50 C - 70 C. Do not exceed 100 C for prolonged periods to avoid color degradation.
Frequently Asked Questions (FAQ)
Q: What does the "1000" in PIBSA 1000 represent?
A: The number 1000 refers to the average molecular weight (Mn) of the Polyisobutylene (PIB) tail. This molecular weight is the industry standard for producing "low-to-mid" molecular weight dispersants, offering a good balance of dispersancy and fluid flow.
Q: Why is "High Reactivity" (HR-PIB) important for PIBSA?
A: High-reactivity PIB contains a high percentage of terminal double bonds (vinylidene). This allows the reaction with Maleic Anhydride to happen thermally without chlorine, resulting in a cleaner product with fewer side reactions and higher "active matter" content.
Q: How does the Saponification (SAP) value affect my formulation?
A: The SAP value indicates the amount of succinic anhydride groups attached to the PIB chain. A higher SAP value generally means more active sites are available to react with amines, allowing you to produce more potent dispersants or emulsifiers.
Q: Is your PIBSA 1000 compatible with group II and III base oils?
A: Yes. PIBSA 1000 and its derivatives exhibit excellent solubility and stability in Group I, II, III, and IV (PAO) base oils.
Q: Can I use PIBSA 1000 directly as a lubricant additive?
A: While PIBSA has some minor anti-rust properties, it is primarily an intermediate. It is designed to be reacted with other chemicals (like polyamines) to create finished additives. For "ready-to-use" dispersants, please see our PIB Bis-Succinimide product page.
