Description

Maleic Acid is a versatile dicarboxylic acid widely used as a key chemical intermediate in industrial synthesis. Its primary value lies in its reactive double bond and two carboxylic acid groups, making it a crucial building block for polymers, resins, and specialty chemicals. This product is essential for manufacturers in the polymer, agrochemical, food additive, and pharmaceutical industries seeking a reliable and high-purity raw material.

Application

• Polymer & Resin Production: A fundamental monomer for unsaturated polyester resins (UPR) and alkyd resins.
• Chemical Intermediate: Used in the synthesis of fumaric acid, malic acid, succinic acid, and various agricultural chemicals.
• Food & Beverage Industry: Employed as an acidulant and flavor enhancer (where compliant with food-grade specifications).
• Metal Treatment & Cleaning: Acts as a chelating agent in metal cleaning formulations and surface treatment processes.
• Pharmaceutical Synthesis: Serves as an intermediate in the production of certain active pharmaceutical ingredients (APIs).
• Oilfield Chemicals: Used in scale inhibitor formulations for water treatment applications.
• Textile Processing: Functions in dyeing and finishing auxiliaries.
• Adhesive & Coating Formulations: A component in specialty adhesives and coatings to modify properties.

Quality Control

Our Maleic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) are provided with every shipment, detailing results for key parameters such as assay, melting point, and impurity profiles. We can supply grades compliant with various industry standards, including Food Chemical Codex (FCC) and technical grades, upon request.

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 product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or quality degradation.
