Trimethylolpropane (TMP), as a critical fine chemical product, demonstrates extensive application value across multiple industrial sectors. Its core uses can be summarized as follows:

I. Resin Synthesis: A Key Raw Material for Enhancing Material Performance

Alkyd and Polyurethane Resins: TMP serves as a cornerstone raw material for synthesizing alkyd and polyurethane resins. Its three hydroxymethyl groups enable cross-linking reactions with organic acids or diisocyanates, significantly improving resin hardness, abrasion resistance, chemical resistance, and weatherability. For example, in automotive coatings, TMP-containing resins enhance UV and acid rain resistance, extending vehicle lifespan.

Unsaturated Polyester and Epoxy Resins: As a chain extender or cross-linker, TMP increases polymer molecular weight, enhancing mechanical properties (e.g., tensile strength, impact resistance) and thermal stability. It is widely applied in aerospace, electronics, and other high-end fields.

Coatings and Inks: Optimizing Performance and Processes

Coatings Industry: TMP is a vital component in high-performance coatings, improving drying speed, gloss, and adhesion. In architectural coatings, TMP-based formulations boost water resistance and anti-fouling properties for exterior walls; in industrial anti-corrosion coatings, their chemical resistance protects metal equipment from corrosion.

Printing Inks: As a solvent or modifier, TMP enhances ink fluidity, drying performance, and printability, suitable for gravure, flexography, and other processes.

II. Plastics and Rubber: Enhancing Material Functionality and Durability

Plasticizers and Stabilizers: TMP derivatives function as heat stabilizers for PVC and other plastics, preventing decomposition during high-temperature processing while improving flexibility and aging resistance.

Engineering Plastics Modification: In nylon, polycarbonate, and other engineering plastics, TMP acts as a chain extender to increase molecular chain length, enhancing impact strength and heat resistance for automotive and electronic applications.

III. Lubricants and Fuels: Improving Industrial Efficiency and Equipment Lifespan

High-Performance Lubricants: TMP-synthesized ester lubricants exhibit low volatility, high viscosity index, and excellent oxidative stability, ideal for high-temperature, high-load applications like steel rolling mills and marine engines.

Aviation Lubricants: Its derivatives are used in advanced aviation lubricants to meet extreme lubrication demands.

Fuel Additives: TMP serves as a fuel stabilizer, preventing oxidative degradation during storage and extending shelf life.

IV. Surfactants and Adhesives: Expanding Application Boundaries

Surfactants: TMP derivatives act as emulsifiers or wetting agents, improving product performance in daily chemicals, textiles, and pesticides. For instance, TMP-based surfactants enhance detergent cleaning power.

Adhesives: As a cross-linker, TMP improves adhesive bond strength and water resistance, widely used in wood processing, packaging, and construction.

V. Pharmaceuticals and Pesticides: Supporting Green Chemistry and Efficient Synthesis

Pharmaceutical Intermediates: TMP and its derivatives synthesize drug carriers and controlled-release materials, enhancing drug stability and bioavailability.

Pesticide Synthesis: As an intermediate, TMP participates in synthesizing low-toxicity, high-efficiency pesticide molecules, promoting sustainable agriculture.

VI. Other Fields: Diversified Application Scenarios

Textile Auxiliaries: TMP functions as a fabric softener or antistatic agent, improving handle.

Composite Materials: In glass-reinforced plastics and rosin esters, TMP acts as a cross-linker to enhance mechanical properties and weatherability.

Electronic Materials: Used in manufacturing sodium ion-selective liquid membrane electrodes, supporting sensor technology development.

VII. Market Trends and Prospects

With sustained growth in global coatings, plastics, and aerospace industries, demand for TMP is steadily rising. For example, Malaysia’s expanding涂料 (coatings) demand and plastic sector growth provide development opportunities for TMP; China, as a leading global producer, further solidifies its market position through technological innovation and capacity expansion. In the future, TMP’s potential in eco-friendly coatings, high-performance engineering plastics, and bio-based lubricants will continue to unlock, driving the industry toward green, high-end transformation.
