Properties and Usage:

1.Glycerol substitutes and dry oil synthesis

Trimethylolpropane(CAS 77-99-6)provides better molecular stability as a glycerol substitute. In dry oil synthesis, it improves oil curing properties and service life.

 

2. Polyester and polyurethane foam production

Trimethylolpropane is used as a key intermediate in polyester and polyurethane foams, significantly improving the strength, hardness, and durability of the foams, as well as improving the water resistance and chemical stability of the polyurethane.

 

3. Alkyd coatings and synthetic lubricants

In the production of coatings and lubricants, trimethylolpropane enhances the robustness, weatherability and corrosion resistance of resins, strengthens sealing and durability, and improves resin hardness and colour tone.

 

4. Plasticisers and surfactants

Trimethylolpropane is used as raw material for plasticizers and surfactants to enhance the flexibility, ductility and thermal stability of plastics, rubber and other materials.

 

5. Explosives manufacturing

Trimethylolpropane is used in the explosives industry to make solid propellant coating and adiabatic layer, which improves the propellant performance by virtue of its stability and heat resistance, and is suitable for the synthesis of high-energy substances.
