Diamylphthalate

Diamyl phthalate (CAS 131-18-0), also known as di-n-pentyl phthalate, is a phthalate-based plasticizer used to impart flexibility and processability to polymer systems.

Where is Diamylphthalate used?

• Plastics and polymer compounding: incorporated into PVC formulations to improve flexibility in films, sheets and molded components
• Rubber and tire manufacturing: processing aid and softener that improves compound workability and reduces mixing viscosity
• Printing inks and packaging coatings: plasticizing additive that maintains film integrity and adhesion under mechanical stress
• Automotive interiors: seals and gaskets achieve required flexibility and durability
• It functions by reducing the glass transition temperature of resins, enabling softer, more pliable end materials.

Good to know: Buyers should confirm purity levels before sourcing.

Commercial specifications

• Drum and IBC quantities; bulk tanker options for larger volumes
