Description

2,5-Furandione, Dihydro-, Monopolyisobutylene Derivs. is a specialized succinic anhydride derivative where the succinic moiety is modified with polyisobutylene chains. This chemical modification imparts unique hydrophobic and oleophilic properties, making it a valuable intermediate for synthesizing surfactants, dispersants, and viscosity modifiers. It is primarily utilized in the formulation of industrial lubricants, fuel additives, and specialty polymers where tailored solubility and compatibility are required. The product is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial applications.

Application

• Lubricant Additives: Acts as a key intermediate for manufacturing succinimide dispersants and detergents used in engine oils and industrial lubricants.
• Fuel Additives: Employed in the synthesis of deposit control additives for gasoline and diesel, helping to keep fuel systems clean.
• Polymer Modification: Used as a functional monomer or modifier to introduce hydrophobic polyisobutylene segments into polymers, enhancing properties like flexibility and water resistance.
• Surfactants & Dispersants: Serves as a precursor for producing non-ionic and anionic surfactants with excellent emulsifying and stabilizing capabilities for industrial formulations.
• Corrosion Inhibitors: Incorporated into protective coatings and oilfield chemicals to provide corrosion protection for metal surfaces.
• Adhesives & Sealants: Functions as a tackifier or compatibility agent in the production of pressure-sensitive adhesives and elastomeric sealants.

Quality Control

Our 2,5-Furandione, Dihydro-, Monopolyisobutylene Derivs. undergoes rigorous quality testing to ensure compliance with industry standards. Key parameters such as acid value, saponification number, and polyisobutylene (PIB) molecular weight distribution are monitored to guarantee performance consistency. Certificates of Analysis (COA) detailing purity, viscosity, and other critical specifications are available upon request for every batch.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
