Description

Poly(Vinyl Chloride), Carboxylated is a modified PVC polymer featuring carboxyl functional groups along its backbone, enhancing its reactivity and compatibility with other materials. This chemical modification is crucial for improving adhesion, dispersion, and mechanical properties in composite formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced polymer blending and modification.

Application

• Adhesive Formulations: Acts as a key reactive polymer to enhance bonding strength, tack, and thermal stability in structural and pressure-sensitive adhesives.
• Coatings and Paints: Used as a film-forming agent and adhesion promoter in water-based and solvent-based coatings, improving substrate wetting and durability.
• Polymer Blends and Alloys: Serves as a compatibilizer to improve the interfacial adhesion between PVC and polar polymers or inorganic fillers.
• Sealants and Caulks: Imparts flexibility, adhesion, and weatherability in elastomeric sealant formulations for construction and automotive applications.
• Textile and Fiber Treatment: Utilized as a binder or coating to modify fabric properties such as water resistance, stiffness, and dyeability.
• Paper Coating: Enhances the strength, gloss, and printability of paper products in functional coating applications.
• Composite Materials: Improves the dispersion and interfacial bonding of fibers or particles in thermoplastic and thermoset composites.
