Description

Polypropylene Glycol Acrylate is a reactive monomer featuring both an acrylate group and a polyether chain, making it a versatile building block for polymer synthesis. This dual functionality is critical for creating materials with tailored properties such as flexibility, hydrophilicity, and crosslinking potential. It is essential for formulators and polymer chemists in industries like UV-curable coatings, adhesives, and specialty polymers seeking to modify the physical characteristics of their final products.

Application

• UV-Curable Coatings & Inks: As a reactive diluent and crosslinker to formulate low-viscosity, flexible, and durable finishes for plastics, metals, and wood.
• Acrylic Resin Modification: To introduce polyether segments into polymer backbones, enhancing flexibility, impact resistance, and adhesion properties.
• Hydrogel Synthesis: For creating hydrophilic, crosslinked networks used in biomedical applications, contact lenses, or wound dressings.
• Pressure-Sensitive Adhesives (PSAs): To adjust tack, peel strength, and cohesion in adhesive formulations.
• Polyurethane Dispersions (PUDs): As a component to incorporate acrylate functionality and improve weatherability and chemical resistance.
• Telechelic Polymers: Serving as a macromonomer for synthesizing block or graft copolymers with specific segmental properties.

Quality Control

Our Polypropylene Glycol Acrylate is manufactured under a strict quality management system. Each batch is analyzed to ensure consistent purity, functionality, and performance. Key parameters monitored include assay (acrylate content), hydroxyl value, color, and viscosity. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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). To prevent premature polymerization, it is recommended to store under an inert atmosphere and to use an appropriate inhibitor as specified in the technical data sheet. Keep away from heat, sparks, and open flame.
