Description

2-Butenedioic Acid(Z)-,Dibutyl Ester,Polymer With Chloroethene is a specialized copolymer of vinyl chloride and dibutyl maleate, designed to impart specific performance characteristics to polymer formulations. This product is valued for its role as an internal plasticizer and processing aid, enhancing flexibility and workability in rigid PVC systems without the migration issues associated with external plasticizers. It is primarily utilized by manufacturers in the plastics, coatings, and specialty adhesive industries seeking to modify the physical properties of their polymeric materials.

Application

• As an internal plasticizer and modifier for rigid and semi-rigid Polyvinyl Chloride (PVC) compounds.
• Used in the formulation of flexible PVC profiles, sheets, and films requiring improved low-temperature performance.
• Key component in PVC-based coatings and adhesives to enhance flexibility and adhesion.
• Processing aid to improve the melt flow and extrusion characteristics of PVC blends.
• Modifier for wire and cable insulation compounds to achieve specific durability and flexibility standards.
• Used in the production of synthetic leather and flooring materials based on PVC.
