Trimethylolpropane (TMP), supplied by SHOEI TRADING (THAILAND), is a trihydric alcohol that serves as a crucial fundamental raw material for developing high-performance ester resin additives. It finds extensive use in various sectors, including polyol esters for lubricants, polyester resins, alkyd resins, and polyurethanes. TMP is distinguished by its exceptional heat resistance, low volatility, and structural stability, making it highly valued in demanding applications such as aircraft and industrial lubricants, and durable resin formulations. Key features of TMP include outstanding thermal resistance, preventing decomposition and volatilization even under high-temperature conditions, and a stable molecular structure that ensures minimal evaporation loss and reduced material changes. Moreover, it is considered a user-friendly industrial raw material due to its low toxicity, relative safety, and minimal legal regulations, simplifying industrial management. Its reliability has been established through years of usage. Primary applications for TMP span lubricant oils, resins, coatings and paints, and adhesives and electronic components. From a technical perspective, its chemical formula is C₆H₁₀O₃, with an approximate molecular weight of 134.17. It presents as a white crystalline solid, is nearly odorless, and exhibits solubility in both water and alcohol.
