Trioctyl trimellitate (TOTM) is an important high-performance plastic additive widely used in a variety of industrial applications. It is a transparent liquid organic acid ester with excellent high temperature resistance. It is often used as a plasticizer for plastic products, especially in applications requiring high heat resistance.
Physical Properties and Chemical Structure
The chemical formula of Trioctyl trimellitate is C33H54O6. Its molecular structure contains three trimellitic acid groups, which form ester bonds with trioctyl alcohol. This structure gives TOTM good heat resistance and chemical stability, allowing it to maintain the stability and flexibility of plastic products under high temperature conditions.
Application Areas
Plastic Plasticizer: TOTM is mainly used as a plasticizer for PVC (polyvinyl chloride) and other plastics. It can significantly improve the heat resistance and weather resistance of plastic products, and is suitable for applications requiring high heat resistance such as automotive interior parts and wire and cable sheathing.
Medical devices: Due to its chemical stability and non-toxicity, TOTM is also widely used in medical devices, such as medical PVC pipes and flexible medical packaging materials.
Industrial coatings: As one of the components of industrial coatings, TOTM can improve the flexibility and corrosion resistance of coatings and is suitable for coating various industrial equipment and pipelines.
Other applications: In addition to the above applications, TOTM is also used in the preparation of flexible cables, synthetic leather, soft plastic products and other fields, and it plays a key role in improving the flexibility and high temperature resistance of materials.
Environmental and health effects
As a highly efficient plasticizer, TOTM has received widespread attention for its environmental and health effects. Although it may be released during manufacturing and use, due to its sealing and stability in most plastic products, the release of TOTM is usually low and will not have a significant impact on the environment and human health.
