Exceval® is a high-performance, water-soluble polymer developed by Kuraray Co., Ltd., a global specialty chemical company based in Japan. As a modified ethylene vinyl alcohol (EVOH) copolymer, Exceval® offers unique properties that make it a versatile material across various industries, particularly in packaging, construction, and textiles. exceval kuraray
One of Exceval®’s most notable features is its excellent barrier performance. It provides exceptional resistance to oxygen, oils, and organic solvents while maintaining transparency and flexibility. These characteristics make it a superior choice in food packaging applications, where maintaining freshness and shelf-life is critical. Unlike traditional EVOH resins that are water-sensitive, Exceval® retains much of its barrier functionality even in high-humidity conditions—an advancement that solves a common limitation in EVOH-based films.
Exceval® is also highly water-soluble and biodegradable, aligning with the growing global emphasis on sustainable and eco-friendly materials. This makes it suitable for use in water-soluble films, detergents, agrochemical packaging, and personal care products. It dissolves cleanly in water, leaving no harmful residue, which is particularly advantageous for applications like detergent pods or laundry bags that dissolve in the wash. Its environmental friendliness has earned it recognition as a responsible choice for companies striving to reduce their carbon footprint and improve the biodegradability of their products.
From a processing standpoint, Exceval® is compatible with various film-forming and coating techniques. It can be used in extrusion, lamination, and even spray-coating methods, offering flexibility in manufacturing and product design. The polymer can be applied as a coating on paper, textiles, and other substrates to impart water resistance, improved printability, or enhanced mechanical strength.
In addition to packaging, Exceval® finds use in construction and civil engineering. When applied to cement or gypsum-based materials, it improves water resistance, workability, and durability. It enhances the adhesion and flexibility of construction materials, making it valuable in mortar, grouts, and tile adhesives.
In the textile sector, Exceval® is used as a binder or coating agent to impart wash durability and breathability while maintaining softness and hand feel. Its film-forming ability allows for high-quality finishes on fabrics, making it suitable for both functional and decorative textile applications.
Kuraray continues to innovate with Exceval® by tailoring grades for specific industrial needs. Whether it's enhancing performance in harsh environments or creating biodegradable, user-friendly products, Exceval® represents the fusion of high performance and sustainability.
In conclusion, Exceval® stands out as a multifunctional material that supports both industrial innovation and environmental responsibility. Its ability to provide a robust barrier, dissolve in water, and be tailored for multiple applications makes it a valuable asset for manufacturers across a broad range of industries. As sustainability becomes a priority, materials like Exceval® will play a key role in developing cleaner, smarter, and more efficient products.
