Trioctyl trimellitate (TOTM) is a yellowish oily liquid. It’s a top – notch plasticizer for resins like PVC. Boasting low volatility, high heat resistance, and good extraction resistance, it offers permanence and excellent electrical properties. Widely used in heat – resistant cable materials, PVC films, and automotive plastic parts.

Main Performance:
- TOTM is a heat-resistant and durable plasticizer, suitable for various resins such as polyvinyl chloride (PVC), nitrocellulose, and polymethyl methacrylate (PMMA).
- This product has good performance in terms of resistance to volatilization, water extraction, migration, low temperature, and electrical properties. Its durability is comparable to that of polymeric plasticizers, while its plasticizing efficiency and processing performance are similar to those of phthalate plasticizers. At the same time, it has some characteristics of both monomeric and polymeric plasticizers.
- It has a high resistivity, and its heat resistance and high-temperature resistance are better than those of DOTP. It is mainly used in heat-resistant cable compounds (105 °C grade), plates, gaskets and other products that require heat resistance and durability.
Trioctyl trimellitate Use
- In the plastic industry: It is a high – performance plasticizer, widely used in resins such as PVC, nitrocellulose, and polymethyl methacrylate. It can improve the heat resistance, durability, and flexibility of plastic products, and is especially suitable for manufacturing heat – resistant cable materials (105 – degree – Celsius – grade), plates, gaskets, and other products that require heat resistance and durability.
- In the electrical industry: Due to its excellent electrical properties and high volume resistivity, it helps to improve the insulation performance of electrical materials, ensuring the safe operation of electrical equipment.
- In other fields: It can also be used in some special coatings and adhesives to improve their performance, such as enhancing the adhesion and heat resistance of adhesives, and improving the weather resistance and flexibility of coatings.
