Description

(Polyethylene-Acrylic Acid) Copolymer is a versatile polymeric material that combines the hydrocarbon backbone of polyethylene with the carboxylic acid functionality of acrylic acid. This unique structure provides excellent adhesion, compatibility, and dispersing properties, making it a critical performance additive in numerous industrial formulations. It is essential for manufacturers in the coatings, adhesives, plastics, and textile industries seeking to enhance product performance, stability, and surface interaction.

Application

• Coatings & Inks: Acts as a dispersing agent, adhesion promoter, and rheology modifier for pigments and fillers in water-based and solvent-based systems.
• Adhesives & Sealants: Improves tack, peel strength, and substrate wetting in pressure-sensitive and structural adhesive formulations.
• Plastics & Polymer Processing: Used as a compatibilizer in polymer blends and as an additive to improve processing and surface properties of polyolefins.
• Textile & Fiber Treatment: Serves as a sizing agent, binder, or finishing chemical to improve fiber cohesion and fabric handle.
• Paper & Packaging: Functions as a coating additive to enhance gloss, printability, and barrier properties.
• Personal Care & Cosmetics: Utilized as a film-forming agent, thickener, or stabilizer in hair and skin care products.
