Polyvinyl alcohol 2488 PVA 2488
Polyvinyl Alcohol (PVA) is produced by the polymerization of vinyl acetate, followed by a controlled hydrolysis process to convert the acetate groups to hydroxyl groups. Polyvinyl Alcohol 2488 (PVA 2488) is a versatile, high-performance polymer known for its unique properties and wide range of applications.
This water-soluble synthetic polymer is characterized by its excellent film-forming, adhesive, and emulsifying capabilities, making it a preferred choice in various industries, including construction, textiles, packaging, and more.
Main features of PVA 2488 Polyvinyl alcohol 2488
Viscosity
Polyvinyl Alcohol 2488 has a medium to high molecular weight, which contributes to its excellent film-forming capabilities and strength. The “2488” typically refers to the degree of polymerization and hydrolysis, indicating a balance between solubility in water and mechanical strength.
Solubility
It is highly soluble in water but insoluble in most organic solvents. This characteristic makes it an excellent binder and stabilizer in aqueous solutions and emulsions. The solubility can vary with the degree of hydrolysis and temperature.
Film Forming
One of the standout properties of PVOH 2488 is its ability to form strong, flexible, and transparent films with good barrier properties. These films are resistant to oils, greases, and solvents, making them suitable for various packaging applications.
Adhesive Properties
2488 serves as an excellent adhesive due to its strong bonding capabilities. It can adhere to a variety of substrates, including paper, wood, and textiles, making it useful in the production of adhesives, paper coatings, and textile sizings.
Applications of PVA 2488
Adhesives
In adhesive formulations, PVOH 2488 serves as a superior bonding agent due to its excellent adhesion properties. It is widely used in wood glue, paper adhesives, and as a binder in specialty adhesives, providing strong, durable bonds and compatibility with various substrates.
Packaging Films and Pouches
PVA 2488 creates strong, transparent films with excellent barrier properties to gases and odors, making it ideal for packaging applications. These films are also biodegradable, offering an environmentally friendly alternative to traditional plastics..
Textile Sizing
For the textile industry, PVA 2488 is used as a warp sizing agent to protect yarn during weaving. It imparts strength and lubrication, reducing breakage rates and enhancing the efficiency of the weaving process. Moreover, its film is easy to remove in the desizing process, ensuring fabric quality.
Paper Coating
PVA 2488 enhances the quality of paper products by increasing their strength, oil resistance, and printability. It is used in paper coatings to produce glossy and durable surfaces ideal for high-quality printing and packaging.
3D Printing
In 3D printing, PVA 2488 is used as a support material due to its water solubility, which allows easy removal of support structures without damaging the printed object. This expands the capabilities of 3D printing, enabling more complex designs and finer details.
Building materials
Incorporating PVA 2488 into building materials aligns with the industry’s move towards more durable, sustainable, and user-friendly construction products. Its multifaceted advantages make it a valuable additive for enhancing the performance and environmental profile of building materials.
