Description

2-Butenedioic Acid (2Z)-, Dioctyl Ester, Polymer With Ethenyl Acetate is a high-performance polymer additive, specifically a copolymer of dioctyl maleate and vinyl acetate. This compound is valued for its ability to impart excellent flexibility, low-temperature properties, and plasticizing effects within polymer matrices. It is primarily utilized by manufacturers in the plastics, coatings, and adhesive industries seeking to modify and enhance the physical characteristics of their products.

Application

• As an internal plasticizer and modifier in polyvinyl chloride (PVC) and other vinyl-based polymers to improve flexibility and processability.
• A key component in the formulation of high-performance industrial coatings and paints, contributing to film formation, adhesion, and durability.
• Used in the production of pressure-sensitive adhesives (PSAs) and sealants to adjust tack, peel strength, and cohesion.
• As a functional additive in printing inks to enhance gloss, rub resistance, and substrate adhesion.
• Employed in the manufacture of synthetic leathers and textile coatings to provide a soft, leather-like hand feel.
• Acts as a processing aid and impact modifier in various engineering plastic compounds.
