Product function:

  1. Used as a plasticizer
    • As a plasticizer, Trimellitic Anhydride has many advantages such as high relative molecular weight, high fluidity, high flash point, low volatility, resistance to various solvent extractions, and low migration resistance.
    • In addition, the benzene polyacid plasticizer has good compatibility with polymer materials, especially PVC materials, and its processability and low temperature performance are similar to those of phthalic acid monomers.
    • Therefore, Trimellitic Anhydride Powder has the advantages of both monomer and polyester plasticizer. It can be used as the main plasticizer for general civilian products, and it can also be used as a cable material with a wider range of applications at 105°C and 125°C. Decorative materials for automotive applications, high-grade spinning oil, impregnating oil for pulsed low-voltage power capacitors, electronic chemicals, and high-tech military products.
  2. Used as a coating and curing agent for epoxy resin
    • The coating industry is moving in the direction of non-toxic and flame-retardant. Using Trimellitic Anhydride and water-soluble resin coatings such as monoethylene glycol, hexanediol, propylene glycol, neopentyl glycol, etc., new water-soluble alkyd resin coatings can be obtained, which can be used in automobiles, refrigerators, etc. .. Electrophoretic coating primer for washing machines, etc.
    • Trimellitic Anhydride can cure epoxy resin in a short time and has excellent physical and chemical properties. It is an ideal epoxy resin curing agent.
    • Trimellitic acid esters can also be used as curing agents. For example, Trimellitic Anhydride reacts with ethylene glycol diacetate to produce ethylene glycol bis(trimellitic acid) ester. This compound reacts with epoxy resin to form heat resistance. Excellent adhesives and coatings.
    • The solid resin obtained by the equimolar reaction of Trimellitic Anhydride owder with glycerin is soluble in solvent and has excellent adhesion to glass and aluminum.
  3. Polymer materials and surfactants
    • Use tribasic acid anhydride and higher fatty alcohols such as lauryl alcohol and stearyl alcohol to control the molar ratio and carry out mono-esterification and double-esterification reactions. Then use NaOH to neutralize the free carboxyl groups of Trimellitic Anhydride to prepare excellent sodium trimellitate anion. Surface active surfactants.
  4. Insulating paint
    • Trimellitic Anhydride can be used as a material for electrical equipment such as glass cloth impregnated laminated resin, heat-resistant covering material, wire insulation varnish, and motor tank insulators.
    • Used as F-class and H-class insulating materials required for electrodes, home appliances, and power tools, such as enameled wire paint, dipping paint, silicon steel plate paint, film, etc.
    • The benzimide resin prepared by the reaction of Trimellitic Anhydride and N,N-diphenyl aromatic diamine can withstand long-term heating at 250-300℃ and can be used for electrical parts, valves, bearings, jet engine parts, etc. Used in manufacturing. Plastic parts.
  5. Other
    • Alkyd resin coatings synthesized by the reaction of Trimellitic Anhydride with polyols and dicarboxylic acids have excellent stability, water resistance and heat resistance, and are electrophoretic coatings for automobiles, refrigerators, washing machines, electrical appliances and mechanical products. Can be used as primer. Surface coatings for kitchens and furniture can also be used as industrial building materials and general coatings.
