Core Performance Advantages of BP24 (2488) in Stationery Glue
Excellent Film-Forming Ability & Initial Tack
As a partially hydrolyzed grade, BP24(2488) retains about 11%–13% acetyl groups, giving it superior surface activity and flexibility.
It penetrates rapidly into hydrophilic stationery substrates (such as paper, cardboard, and wood pulp) to form a tough, smooth dry adhesive film with strong initial grab.
Superior Water Solubility & Outstanding Washability (Child-Friendly)
Compared to fully hydrolyzed grades (e.g., BF17/BF24), BP24(2488) is partially hydrolyzed, dissolving much faster in cold and warm water for easier processing.
Easy Washability: If glue stains clothes or tabletops, it remains water-soluble after drying and washes off easily with warm water-fully meeting child safety and easy-cleaning requirements.
Optimal Viscosity & Pseudoplastic Flow Experience
A degree of polymerization around 2,400 provides high thickening efficiency and ideal rheological behavior.
It squeezes smoothly and flows evenly without being too runny (which causes paper wrinkling or over-penetration) or too tacky to spread.
High Transparency & Gloss
Dissolved BP24 yields an ultra-clear, transparent aqueous solution. In clear liquid glue formulations for students, it provides a premium crystal-clear appearance without yellowing after drying.
Good Freeze-Thaw & Re-dissolution Stability
Partially hydrolyzed PVA is far less prone to gelling than fully hydrolyzed counterparts. The glue resists crystallization and whitening during cold winter storage, extending shelf life.
Specific Applications of BP24(2488) in Key Stationery Products
1. Traditional Liquid Office/Student Clear Glue (PVA Water-Based Glue)
Role: Primary film-forming binder.
Effect: Delivers appropriate viscosity, paper bonding strength, and post-drying transparency.
2. Glue Stick Auxiliary Component
Role: Toughening agent and co-film-former (often blended with PVP or PVA BP05/BP17).
Effect: Balances glue stick hardness with smooth application, preventing the dried layer from cracking.
3. Watercolor/Acrylic/Craft Art Glue & DIY Slime Base
Role: Polymer reaction precursor.
Effect: With high molecular weight and reactive hydroxyl groups, BP24(2488) crosslinks with borax/boric acid agents to form a stretchable, elastic, non-sticky gel network.
