Description

Diisooctyl Fumarate is a high-purity diester of fumaric acid and isooctyl alcohol, valued for its excellent plasticizing properties and compatibility with a wide range of polymers. This compound is crucial for formulators seeking to enhance the flexibility, durability, and processing characteristics of various synthetic materials. It is primarily needed by manufacturers in the plastics, coatings, and specialty chemical industries for producing high-performance products.

Application

• Primary plasticizer for polyvinyl chloride (PVC) and other vinyl polymers.
• Co-monomer or crosslinking agent in polymer synthesis and resin production.
• Intermediate for the synthesis of specialty chemicals and lubricant additives.
• Plasticizer for adhesives, sealants, and caulking compounds.
• Additive in coatings and inks to improve film flexibility and adhesion.
• Component in personal care product formulations (e.g., emollient, solvent).
