Description

Dioctyl Fumarate is a high-purity diester of fumaric acid, widely recognized for its excellent performance as a plasticizer and chemical intermediate. This compound is valued for its ability to impart flexibility, low-temperature properties, and durability to polymer matrices. It is a critical material for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable and consistent raw materials.

Application

• Primary Plasticizer for polyvinyl chloride (PVC), polyvinyl acetate (PVAc), and other synthetic resins to enhance flexibility and processability.
• Internal Plasticizer in the production of adhesives, sealants, and caulks to improve adhesion and elasticity.
• Co-Reactant / Monomer in copolymerization reactions to modify polymer properties such as glass transition temperature and solubility.
• Lubricant Additive and viscosity modifier in specialty lubricants and functional fluids.
• Synthetic Intermediate for the manufacture of more complex esters, surfactants, and specialty chemicals.
• Film Former in coatings and inks, contributing to film flexibility and substrate adhesion.
