Polyvinyl Alcohol (PVA), 99-100% Hydrolyzed, Reagent Grade

The Reagent Grade designation ensures this is the highest commercial quality available, manufactured by Spectrum to meet rigorous standards for purity and consistency in demanding applications.

Features:

• Fully Hydrolyzed (99–100%) - Provides superior chemical resistance, tensile strength, and gas barrier properties
• High-Purity Reagent Grade - Specifically processed to meet the toughest regulatory standards for laboratory and industrial research
• Exceptional Film-Forming - Ideal for creating clear, strong, and grease-resistant coatings or films
• Water-Soluble Polymer - Can be dissolved in hot water to create stable, non-toxic solutions for various protocols

Common Applications:

• Material Science: Synthesis of hydrogels, nanofibers, and biodegradable plastics
• Paper & Textiles: Used as a high-strength sizing agent and coating to improve surface smoothness and oil resistance
• Laboratory Adhesives: Acts as a binder for various powders and as a thickener in aqueous solutions
• Microscopy: Used in the preparation of specialized mounting media and as a stabilizing agent in emulsions

Preparation Note: To effectively dissolve 99-100% hydrolyzed PVA, it is typically necessary to heat the water to approximately 85°C to 95°C while stirring continuously. Fully hydrolyzed grades do not dissolve well in cold water.
