Product Overview

Trimethylolpropane (TMP) is a trifunctional polyol supplied in solid form. It is soluble in water, low carbon alcohol, glycerol, N,N-dimethylformamide, partially soluble in acetone and ethyl acetate, slightly soluble in carbon tetrachloride, ether and chloroform, and insoluble in aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons. It has strong hygroscopicity.

TMP is mainly used in the production of alkyd resin, polyurethane, unsaturated resin, polyester resin, coatings, and the synthesis of aviation lubricant, printing ink, etc. It can also be used as a heat stabilizer for textile additives and polyvinyl chloride resin.

Industrial Applications

Trimethylolpropane (TMP) is a widely used organic chemical intermediate. It is mainly used as a raw material for polyurethane resin, alkyd resin, and high-grade coatings. It is also an essential intermediate for other resins and organics. Its strong chemical structure enables it to help end products withstand extreme temperature changes and high mechanical stress, and has excellent UV and chemical resistance.

TMP can improve the film’s hardness, gloss, and durability when used to manufacture polyurethane and alkyd coatings. TMP is biodegradable, non-toxic, and has been approved for use in various food contact applications.

Storage & Transportation Cautions

Store in a cool, ventilated warehouse separately from oxidizers and acids. Keep away from fire and heat sources. The storage area should be equipped with fire apparatus and leakage containers.

The packaging should be complete and the load should be secure when starting transportation. Ensure that the package does not leak, collapse, fall, or get damaged. The product is strictly forbidden to mix with oxidizers and acids. The package should be protected from sun exposure, rain, and high temperature.
