Market Position/ History

Tokuyama Corporation, founded in 1918 as Nihon Soda Kogyo Co., Ltd. in Tokuyama, Japan, initially focused on soda ash production. Over the decades, it expanded into cement, petrochemicals, fine chemicals, and electronics, with key milestones such as entering the polyvinyl chloride and aluminum nitride businesses in the 1960s and 1980s, respectively. In the 1990s, it diversified further into high-purity chemicals for electronics and launched ventures in recycling and environmental businesses. In recent years, Tokuyama has focused on restructuring its portfolio, acquiring A&T Corporation in 2021, launching the Medium-Term Management Plan 2025, and establishing new ventures, including a joint venture in South Korea (STAC Co., Ltd.) for high-purity chemicals in 2022. The company has also absorbed Tokuyama Information Service Corporation in 2023, continuing its transformation toward electronics, life sciences, and environmental sectors.

Product Description

EXCELICA High-Purity Fused Spherical Silica

EXCELICA is a high-purity, fused synthetic spherical silica produced through a vapor phase reaction process. Designed for specialized industrial and semiconductor applications, EXCELICA is characterized by its exceptional purity and controlled particle size distribution, ranging from several microns up to 100 microns. Coarse grain cut grades are available to meet the specific requirements of various applications.

Product Features:

Chemical Composition: SiO2 (Silicon Dioxide)

Purity: Produced in a closed system using highly purified materials, EXCELICA features an extremely low level of impurities. This includes minimal amounts of harmful trace elements such as uranium or thorium (less than 0.1 ppb), which can cause malfunction in semiconductor devices due to alpha radiation.

Structure: Amorphous, as confirmed by X-ray diffraction analysis, ensuring stable and consistent performance across applications.

Particle Size Range: From several microns up to 100 microns, with coarse grain grades available for specific requirements.

Applications: EXCELICA is widely used in industries that demand high-purity silica, including:

Encapsulants for Semiconductors: Protects semiconductor components from environmental damage while ensuring optimal performance.

Hole-Plugging Materials for Substrates: Used in semiconductor packaging to seal holes in substrates.

Die Bonding Materials: Ensures effective and secure bonding of semiconductor dies.

Precision Adhesives: For applications requiring exact precision and high purity in bonding.

Quartz Materials: Suitable for high-precision quartz-related manufacturing processes.

Films and Coatings: Used in creating specialized films and coatings in electronics and optics.

Packaging: Available in flexible containers or paper bags, designed for easy handling and shipping.

EXCELICA's superior purity and amorphous structure make it ideal for high-precision applications, especially where low contamination levels and high reliability are paramount.

EXCEBEADS Spherical Amorphous Silica Beads

EXCEBEADS is a high-purity, spherical, non-porous silica with a particle size ranging from 3 to 10 μm, produced using TOKUYAMA's unique vapor phase reaction process. Known for its excellent sphericity and amorphous structure, EXCEBEADS is designed primarily for use in healthcare and cosmetic applications, serving as an eco-friendly alternative to microplastic beads.

Product Features:

Chemical Composition: SiO2 (Silicon Dioxide)

Particle Size Range: 3 to 10 μm, ensuring a narrow and uniform distribution for optimal performance in various formulations.

Purity: Manufactured in a closed system using highly purified materials, EXCEBEADS contains minimal impurities, including traces of radioelements, heavy metals, or ionic elements.

Structure: Amorphous, confirmed by X-ray diffraction, contributing to its stable, consistent properties across applications.

Non-Porous: Its non-porous nature ensures no impact on the product’s viscosity or function.

Applications: EXCEBEADS is highly versatile, particularly in cosmetic and personal care products, where it can replace microplastic beads. Key applications include:

Microplastic Bead Alternatives: A sustainable choice to replace microbeads, aligning with eco-friendly initiatives.

Makeup Products: Used in foundations, face powders, and other makeup formulations to improve texture and performance.

Sunscreen: Enhances the sensory feel and stability of sunscreen products.

Special Characteristics:

Silky Smooth Skin Feel: The uniform particle size distribution provides a soft, smooth texture, enhancing the skin feel of products.

Soft Focus Effect: Reduces the appearance of wrinkles and pores by minimizing uneven skin texture both physically and optically.

Polishing/Scrubbing Effect: The spherical particles act as a gentle scrubbing agent, offering a natural, skin-friendly alternative to traditional plastic beads.

Eco-Friendly: EXCEBEADS offers a sustainable solution with a natural origin index of 1 (according to ISO 16128), making it environmentally friendly.

Volume Enhancement: Acts as a chemically stable excipient that increases volume without excessive thickening, while being gentle and safe for the skin.

Packaging: Available in paper bags for convenient handling and shipping.

EXCEBEADS is an ideal choice for cosmetic formulations aiming to deliver high performance, skin-friendly benefits, and contribute to environmental sustainability.
