PVA 2488 Application

PVA 2488 is a universal core model in polyvinyl alcohol, which is soluble in cold water, has good film-forming properties, is environmentally friendly, and odorless. At the same time, due to its higher degree of polymerization, it achieves higher adhesive strength, better film-forming density/hardness, and significantly improved water resistance/tensile strength. It belongs to the medium- to high-water-resistant PVA.

PVA 2488 is a core raw material for high-end accessories across industries such as building materials, textiles, and adhesives. It is also a key stocking model for PVA distributors. The following are its core application areas, specific adaptation scenarios, and functions:

PVA 2488 Used For Textile Industry

PVA 2488 suitable for high-count and high-density yarns, synthetic fibers, heavy-duty fabrics, and high-speed weaving, it is the core material for high-end warp sizing in textile pretreatment, solving the problem of yarn breakage and wear in high-demand weaving with ordinary PVA.
High end warp yarn sizing: used for sizing heavy-duty fabrics such as cotton and linen high count yarn, polyester/nylon filament, canvas/denim, etc., forming a more wear-resistant and tough dense film on the surface of the yarn, protecting the yarn from breakage and fuzzing during high-speed weaving, and greatly improving weaving efficiency.
High-precision printing paste: Mix high-end textile printing pigments to improve their stability and leveling, making printed patterns clearer and edges more regular, suitable for fine printing in home textiles and high-end clothing.

PVA 2488 Used For Paper Industry

PVA 2488 suitable for the production of high-end paper and heavy-duty packaging paper/cardboard, it serves as a surface and internal sizing agent, greatly improving the physical strength, water resistance, and printing adaptability of paper, thereby solving shedding hair, powder, and poor folding resistance issues in high-speed printing of ordinary paper.
Surface Glue: Used for copperplate paper, lightly coated paper, high-end office paper, kraft paper/corrugated paper, to form a dense film on the surface of the paper, improve the surface strength, water resistance, smoothness, and stiffness of the paper, reduce hair and powder shedding in high-speed printing, and enhance printing clarity.
Internal glue application: added to high-end pulp and heavy-duty packaging paperboard pulp to enhance the bonding strength between paper fibers, making the paper/paperboard stronger and more durable, suitable for the production of honeycomb paperboard and heavy-duty packaging paperboard, and improving the load-bearing and damage resistance of the paperboard.
Special paper bonding: used in the production of thermal paper, release paper, and high-end decorative paper, as a bonding agent to enhance the interlayer bonding force of the paper, ensuring the forming stability and performance of special paper.

PVA 2488 Used For Adhesive Industry

PVA 2488 is the basic core raw material for the production of high-end water-based adhesives. With its high bonding strength, it has become a key ingredient in upgrading white emulsion adhesive, polyvinyl acetate lotion (PVAc), and other adhesives, and is suitable for heavy bonding and wet environment bonding applications.
High-end composite adhesive: high-end woodworking white latex, heavy-duty packaging adhesive, modified urea formaldehyde adhesive/phenolic adhesive. Adding them can significantly improve the adhesive strength, water resistance, and stability, making it suitable for scenarios such as wood splicing, heavy-duty cardboard box sealing, and board bonding.
High-end stationery adhesive: high-viscosity solid adhesive, moisture-resistant liquid adhesive, stronger adhesion, less prone to softening and peeling in humid environments, suitable for high-end stationery adhesive needs in offices and classrooms.

PVA 2488 Used For Coatings

PVA 2488 suitable for high-demand industrial coatings and high-end packaging inks, it serves as a film-forming/bonding material and can replace more resins, improving product water resistance, friction resistance, and scratch resistance while controlling costs.
Water-based coatings: high-end water-based wood coatings, industrial water-based anti-rust coatings, water-based engineering machinery coatings, used as film-forming adhesives to enhance the adhesion, scratch resistance, and water resistance of paint films.
Water-based ink: high-end packaging ink for food, specialized ink for plastic film, and high-friction resistant ink for flexographic/gravure printing. As the core connecting material, it disperses pigment particles more evenly, improves ink drying speed and printing clarity, and is water- and friction-resistant after film formation.

It is not easy to bleed or fade after printing, making it suitable for high-end printing applications such as food vacuum packaging and plastic film packaging.

PVA 2488 Used For Building Materials

PVA 2488 relying on its high viscosity and water resistance, PVA has become the preferred additive for high-end building materials, large-scale construction, and outdoor/humid environment applications. It is the core additive for high-end dry powder mortar and waterproof building materials.

High-end dry powder mortar: tile adhesive for rock panels, waterproof putty, flexible putty for exterior walls, and mortar for integrated insulation boards.

Waterborne architectural coatings: Exterior latex paint and waterproof interior wall paint serve as film-forming agents and thickeners, enhancing adhesion, scrub resistance, and weather resistance, making the paint film denser and less prone to peeling and powdering from rain and sun exposure.
