PVA 2488 High-Viscosity Grade for Construction Materials

PVA 2488 is a high-viscosity polyvinyl alcohol grade developed for applications requiring elevated bonding strength, structural integrity, and enhanced mechanical performance. Featuring viscosity values around 44–50 mPa·s and a hydrolysis degree of approximately 87–89%, this material produces strong, resilient films with excellent load-bearing capacity. It is frequently incorporated into dry-mix mortars and gypsum-based building materials to improve adhesion, flexibility, and crack resistance. In emulsion polymerization systems, PVA 2488 functions effectively as a protective colloid, contributing to stable particle distribution and improved final polymer properties. Screen printing adhesives and specialty coatings also benefit from its thickening behavior and cohesive strength. PVA 2488 is particularly valued in industrial environments where durability and formulation robustness are required. Selection of this grade supports high-performance construction and manufacturing processes. For detailed application matching or pricing inquiries, customers are encouraged to contact us directly.
