Description

Product Detail

Maleic Acid with CAS 110-16-7 is an important dual-purpose raw material for fine chemical industry and food additives, produced by benzene oxidation and recrystallization purification. Our factory supplies 99% high-purity maleic acid, divided into industrial grade and food grade for global buyers.

The product is neat white crystal powder with mild sour flavor. It dissolves quickly in water and organic alcohols, and will sublime under heating condition. Industrial maleic acid is mainly used to synthesize unsaturated polyester resins for fiberglass products, coatings and casting materials. It also serves as key intermediate for water treatment scale inhibitors, textile dye auxiliaries and plastic softeners.

Food grade maleic acid is strictly controlled for heavy metal and arsenic impurities, complying with international food additive specifications. It works as acidity regulator and antioxidant synergist in canned food, beverages and baking products, improving flavor stability and extending shelf life.

Compared with similar dicarboxylic acids, maleic acid features high reaction activity and low production cost. Its uniform crystal shape avoids pipeline blockage during automatic feeding, and produces few insoluble impurities after dissolution to guarantee stable downstream product quality. Each batch is fully tested before delivery with complete quality documents to support incoming inspection and customs clearance.

Storage requirements: Store in cool, dry and ventilated warehouse, keep bags tightly sealed to prevent moisture absorption and caking. Avoid mixing with alkaline chemicals and oxidants. Operators just need ordinary dust masks during feeding without strong corrosion risk. We support trial small orders and full-container bulk wholesale with fast delivery.
