Description

Poly(4-Hydroxybutyl Acrylate) is a functional polymer derived from the polymerization of 4-hydroxybutyl acrylate, characterized by pendant hydroxyl groups along its carbon chain backbone. This structure provides valuable properties such as hydrophilicity, reactivity, and the ability to form cross-linked networks, making it a versatile intermediate for advanced material synthesis. It is primarily sought by R&D and production teams in the specialty polymer, coatings, adhesives, and biomedical sectors for developing products with tailored surface characteristics and performance.

Application

• Hydrophilic Coatings and Films: Used to formulate coatings for medical devices, membranes, and optical lenses that require moisture management and anti-fog properties.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in the synthesis of acrylic-based PSAs, enhancing tack, peel adhesion, and cohesion for labels and tapes.
• Polymer Modification and Cross-linking: Acts as a reactive polyol for cross-linking with isocyanates or epoxy resins to produce thermosetting polymers with improved mechanical strength and chemical resistance.
• Biomedical Hydrogels: Employed in the development of biocompatible hydrogels for drug delivery systems, wound dressings, and tissue engineering scaffolds.
• Ink and Toner Resins: Utilized as a functional additive in toner and inkjet ink formulations to improve pigment dispersion, binding, and final print quality.
• Surface Modifiers for Nanoparticles: Provides a polymeric shell for surface functionalization of nanoparticles, enhancing their stability and compatibility in composite materials.

Quality Control

Our Poly(4-Hydroxybutyl Acrylate) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in molecular weight distribution, hydroxyl value, residual monomer content, and other critical parameters. A Certificate of Analysis (COA) detailing the specific results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). As the polymer may be hygroscopic, it is recommended to keep the container sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent moisture absorption and potential property changes.
