Description

Dipentyl Fumarate is a diester of fumaric acid and pentanol, widely recognized by its CAS registry number 20314-74-3. This compound serves as a versatile intermediate and functional additive, valued for its ability to modify polymer properties and act as a reactive diluent. It is essential for manufacturers in the polymer, coatings, and specialty chemical industries seeking to enhance product performance and processing characteristics.

Application

• Polymer Plasticizer & Modifier: Used to improve the flexibility, workability, and low-temperature performance of PVC, acrylics, and other polymer systems.
• Crosslinking Agent & Monomer: Functions as a diester monomer in the synthesis of unsaturated polyester resins and other cross-linked polymers.
• Reactive Diluent: Employed in radiation-curable coatings, inks, and adhesives to reduce viscosity without compromising final film properties.
• Lubricant & Processing Aid: Acts as an internal lubricant and mold release agent in plastic and rubber compounding processes.
• Chemical Intermediate: Serves as a key building block for the synthesis of more complex esters, surfactants, and specialty chemicals.
• Solvent & Carrier: Utilized as a high-boiling-point solvent for dyes, pigments, and other additives.
