Description

Bis(2-Ethyloctyl) Phthalate is a high-molecular-weight phthalate plasticizer known for its excellent permanence and low volatility. This compound is valued for its ability to impart flexibility, durability, and low-temperature performance to polymer matrices. It is primarily required by manufacturers in the plastics, coatings, and specialty chemical industries seeking a high-performance plasticizer for demanding applications.

Application

• Primary plasticizer for PVC (polyvinyl chloride) and other vinyl polymers.
• Enhances flexibility and workability in wire and cable insulation and jacketing compounds.
• Imparts durability and low-temperature properties to synthetic leather and coated fabrics.
• Used in the formulation of adhesives, sealants, and caulking materials.
• Plasticizer for polymer films and sheets requiring extended service life.
• Component in specialty lubricants and functional fluids.
• Used in the production of printing inks and colorants.
