Description

Isooctyl Tallate is a high-performance synthetic ester derived from tall oil fatty acids and isooctyl alcohol. This versatile chemical intermediate is valued for its excellent solvency, lubricity, and plasticizing properties, making it a critical component in advanced formulations. It is primarily utilized by manufacturers in the polymer, lubricant, and specialty chemical industries seeking reliable and consistent raw materials for their production processes.

Application

• As a plasticizer and secondary co-stabilizer in PVC and other polymer systems to enhance flexibility and processing.
• As a base fluid or additive in synthetic lubricants and metalworking fluids, providing good thermal stability and lubricity.
• As a solvent and carrier in industrial coatings, inks, and adhesive formulations.
• As a chemical intermediate for the synthesis of more complex esters and specialty surfactants.
• As a processing aid in rubber compounding to improve mold release and internal lubrication.
• In the formulation of release agents and demolding compounds for various industrial molding processes.

Quality Control

Our Isooctyl Tallate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for acid value, saponification value, viscosity, and color. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids, oxidizing agents, and heat sources. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and maintain product integrity.
