High degree of hydrolysis (~99%) ensuring excellent water solubility and film-forming capability.
Consistent molecular weight distribution (viscosity grade 17–22 mPa·s for 4% aqueous solution at 20°C).
Low residual acetate content (<1.5%), contributing to superior thermal stability and chemical resistance.
Free-flowing white granular or powder form with low dust generation for safe handling and metering.
Non-toxic, biodegradable, and compliant with GB/T 12010.1–2009 and ISO 15236 standards.
Binders in ceramic green bodies and refractory shaping processes.
Thickener and stabilizer in textile sizing formulations for warp yarn protection.
Adhesive component in paper coating, laminating, and corrugated board production.
Dispersant and protective colloid in emulsion polymerization (e.g., VAE, SBR latex synthesis).
Base polymer for water-soluble films used in agrochemical packaging and detergent pods.
