Itaconic acid/2 – Methylenesuccinic Acid/CAS:97-65-4

I. Polymer Materials Field (Core Application)

1. Synthetic Resins and Plastics

   As a comonomer, it copolymerizes with acrylonitrile, styrene, acrylate and other monomers to produce modified resins (e.g., acrylic resins, unsaturated polyester resins). These resins are used in manufacturing weather-resistant coatings, high-strength plastics and engineering plastic components, which can improve the toughness, heat resistance and corrosion resistance of the products.
2. Synthetic Rubber

   It is used in preparing synthetic elastomers, enhancing the tensile strength, wear resistance and aging resistance of rubber. It can replace part of nitrile rubber and be applied to seals, hoses, tires and other products.
3. Water-based Coatings and Adhesives

   Serving as a dispersant and crosslinking agent, it is used in producing environment-friendly water-based coatings (e.g., latex paints, industrial anti-corrosion coatings) and water-based adhesives, reducing the VOC content of products to meet environmental regulations. Meanwhile, it can improve the adhesion and water resistance of coatings.

II. Specialty Chemicals Field

1. Surfactants

   It is used to synthesize amphoteric ionic surfactants, which are applied in detergents, emulsifiers, printing and dyeing auxiliaries, etc. These surfactants have excellent decontamination, emulsification and dispersion effects, as well as good biodegradability.
2. Lubricating Oil and Fuel Additives

   It is used in preparing extreme pressure anti-wear additives for lubricating oils, improving the stability of lubricating oils under high temperature and high pressure conditions. It can also be used as a fuel additive to enhance fuel combustion efficiency and reduce carbon deposit formation.
3. Water Treatment Agents

   It is used to synthesize scale inhibitors and corrosion inhibitors for industrial circulating water and boiler water treatment. These agents can effectively inhibit the deposition of scales such as calcium carbonate and calcium sulfate, and protect metal equipment from corrosion.

III. Food and Pharmaceutical Field

1. Food Additives

   As a pH regulator and acidulant, it is applied in beverages, jams, candies and other foods to adjust acidity and improve taste. It can also be used as a raw material for food preservatives to extend the shelf life of foods (food-grade purity standard ≥ 99.5% is required).
2. Pharmaceutical Intermediates

   It is used in synthesizing intermediates for antibiotics and antifungal drugs. It can also be used as a matrix component of external ointments to enhance the transdermal absorption effect of drugs.

IV. Other Fields

1. Paper Industry

   As a paper strengthening agent and sizing agent, it improves the strength, folding endurance and water resistance of paper, and is suitable for producing high-grade cultural paper and packaging paper.
2. Textile Industry

   As a printing and dyeing fixing agent and fiber modifier, it enhances the adhesion of dyes on fibers and reduces fading. Meanwhile, it improves the moisture absorption and antistatic properties of fibers.
