TRIMETHYLOL PROPAN - TMP Details

What Is TMP (Trimethylol Propane)?

TMP (Trimethylol Propane) is a multifunctional polyol.
With the chemical formula C₆H₁₄O₃, it is an essential building block used in the production of polyurethanes, alkyd resins, coating chemicals, and synthetic lubricant esters.

Because it contains three hydroxyl (–OH) groups, TMP is highly reactive and plays a critical role in forming crosslinked polymer structures.


🔧 What Is TMP Used For?

The primary function of TMP is to create crosslinking in polyurethane and other polymer systems, enhancing durability and mechanical strength.

Main functions:

1. Key Component in Polymer & Resin Production

TMP is one of the core raw materials for polyurethane, polyester, and alkyd resin synthesis.

2. Forms Crosslinked Structures

By creating connections between polymer chains, TMP helps produce materials that are:

  • Stronger
  • More durable
  • More chemically resistant

3. Used in Synthetic Ester Lubricants

It improves high-temperature stability and oxidation resistance in synthetic oils.

4. Enhances Reactivity in Coating Systems

Improves gloss, adhesion, hardness, and durability in varnishes, paints, and industrial coatings.

5. Provides Flexibility & Stability in PU Systems

Enhances mechanical performance in polyurethane foams, elastomers, and adhesives.


🎯 Purposes of TMP

1. Polyurethane Production

Used in PU foams, coatings, elastomers, and adhesive formulations.

2. Alkyd & Polyester Resin Manufacturing

TMP is an essential ingredient in:

  • Varnishes
