What is EXCEVAL™?

EXCEVAL™ is a high-quality polyvinyl alcohol resin produced by Kuraray, a global leader in specialty chemicals. It is specifically engineered to provide enhanced functionality compared to standard PVOH materials.

What sets EXCEVAL™ apart is its excellent balance of solubility, strength, and durability. It can dissolve in water under controlled conditions, yet maintain strong mechanical properties during use. This makes it ideal for applications where both performance and removability are essential.

Key Properties of EXCEVAL™

The success of EXCEVAL™ lies in its advanced material characteristics:

Controlled Water Solubility
EXCEVAL™ is designed to dissolve at specific temperatures, allowing manufacturers to control when and how the material breaks down.

Outstanding Film Formation
It forms clear, strong, and flexible films that are widely used in coatings and packaging solutions.

High Chemical Resistance
Compared to conventional PVOH, EXCEVAL™ offers improved resistance to solvents, oils, and chemicals.

Low Impurity Levels
Its high purity ensures consistent performance, especially in sensitive applications such as electronics and pharmaceuticals.

Excellent Adhesion
It provides strong bonding properties, making it suitable for use in adhesives and binders.

Applications of EXCEVAL™

EXCEVAL™ is used across a wide range of industries due to its versatility and reliability:

1. Water-Soluble Packaging
One of the most popular applications is in water-soluble films for packaging detergents, agrochemicals, and cleaning products. These films dissolve completely, reducing plastic waste and improving user convenience.

2. Ceramic Industry
In ceramics, EXCEVAL™ acts as a binder that enhances the strength of green bodies. It improves handling and reduces breakage before firing, leading to higher production efficiency.

3. Emulsion Polymerization
EXCEVAL™ is widely used as a protective colloid in emulsion polymerization processes, helping to stabilize particles and improve product consistency.

4. Electronics and Optical Films
Due to its purity and film-forming ability, EXCEVAL™ is used in electronic components and optical films where precision and clarity are critical.

5. Textile Industry
It is used as a sizing agent to strengthen yarns during weaving, improving efficiency and reducing defects.

Benefits of Using EXCEVAL™

Manufacturers choose EXCEVAL™ for several compelling reasons:

Enhanced Performance
It offers superior strength, stability, and reliability compared to standard PVOH products.

Sustainability
Its water solubility and environmentally friendly profile support greener production practices.

Process Efficiency
EXCEVAL™ simplifies manufacturing processes by reducing defects and improving consistency.
