AI Overview
PVA 088-50 (or 2488) is a high-viscosity, partially hydrolyzed polyvinyl alcohol (PVA) resin, appearing as a white to slight yellowish granular or powder solid. It is widely used in adhesives, textile sizing, and as a protective colloid in emulsion polymerization due to its excellent water solubility, film-forming, and adhesion properties.
Key Characteristics
- Grade: Partially hydrolyzed (typically 87-89 mol% hydrolysis).
- Viscosity: High viscosity (typically 44-52 mPa·s or cp, 4% aqueous solution at 20°C).
- Solubility: Excellent water-solubility with low dissolution temperatures.
- Properties: Strong adhesion, flexibility, oil resistance, and gas barrier properties.
Main Applications
- Adhesives: Used in paper binding, woodworking, and as a re-wetting adhesive.
- Emulsion Polymerization: Acts as a protective colloid for producing PVAc, VAE, and acrylate emulsions, enhancing freeze-thaw stability and mechanical shear stability.
- Textile & Paper: Functions as a sizing agent to improve strength and reduce abrasion in textiles and as a surface sizing agent for paper.
- Construction: Additive in coatings and mortar formulations.
