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. It functions by reducing the glass transition temperature of resins, enabling manufacturers to produce softer, more pliable end materials across a range of industrial applications.

In plastics and polymer compounding, it is incorporated into PVC formulations to improve flexibility in films, sheets, and molded components for various manufacturing sectors. Rubber and tire manufacturers use it as a processing aid and softener to improve compound workability and reduce mixing viscosity during the intensive production stages.

In printing inks and packaging coatings, it acts as a plasticizing additive that helps maintain film integrity and adhesion under significant mechanical stress and pressure. Automotive interior components, including seals and gaskets, may incorporate this chemical to achieve the required flexibility and durability specifications for long-term use.

The product is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for larger procurement volumes and industrial supply chains. It is typically offered in technical grade, which is the standard specification for industrial plasticizer applications. Buyers should confirm purity levels before sourcing.
