Core offering

Oriental Silicas Corporation manufactures and distributes specialty silica products, including precipitated silicon dioxide (white carbon), solid and liquid sodium silicate, synthetic sodium aluminum silicate, synthetic calcium silicate, and vulcanized vegetable oil. These products are sold to industrial customers in the tire, rubber, food, pharmaceutical, cosmetics, paint, paper, and battery industries across Asia Pacific and globally.

Product overview

Oriental Silicas Corporation is a specialty chemical manufacturing and sales company offering a portfolio of silica-based products. The core product is Precipitated Silicon Dioxide (White Carbon), marketed under sub-brands TOKUSIL®, EECOSIL®, OSC®, FINESIL®, and OSCMATT® for tire reinforcement, industrial rubber, dental, food, and coating applications. Complementary products include Solid/Liquid Sodium Silicate (OSC® SL-Series), VVO® (Vulcanized Vegetable Oil) for rubber processing, Synthetic Sodium Aluminum Silicate (OSC® AS-Series) for rubber reinforcement and industrial applications, and Synthetic Calcium Silicate (OSC® CS-Series) for food and cosmetics. In 2024, the company launched the sustainable NZEROSIL series of Renewable Silica products.

Products and services

• Precipitated Silicon Dioxide (White Carbon) High-purity amorphous silicon dioxide synthesized through acid precipitation of sodium silicate with sulfuric acid. Used as reinforcing filler for industrial rubber (reducing rolling resistance and improving wet traction in tires), as well as carrier, free-flow agent, and anti-caking additive in dental, food, feed, and pharmaceutical applications.
• Solid/Liquid Sodium Silicate (OSC SL-Series) Sodium silicate product available in both solid and liquid forms. Used in detergent manufacturing, foundry applications, soil improvement, paper pulp recycling (deinking agent), and as a critical raw material for synthesizing precipitated silica, silica gel, and colloidal silica.
• VVO (Vulcanized Vegetable Oil) Vulcanized vegetable oil functioning as a permanent softener, thixotropic process aid, complementary filler, and surface modifier for rubber processing applications.
• Synthetic Sodium Aluminum Silicate (OSC AS-Series) Synthetic amorphous sodium aluminum silicate providing technical rubber reinforcement properties, used as an extender for titanium dioxide in water-based paint and paper, and as a non-toxic carrier for food, animal feed, and pharmaceutical applications.
• Synthetic Calcium Silicate (OSC CS-Series) Synthetic calcium silicate with notable oil and water absorbability and large micro-pore/total pore volume, serving as a super carrier for food, agricultural, and cosmetics applications.
• NZEROSIL Series (Renewable Silica) Renewable precipitated silica product line, with the Phase 1 RH Series produced from rice husk ash, providing an eco-friendly alternative to conventional precipitated silica for industrial applications.

Expansion highlights5 records

Broad incumbents

• PPG Industries: Former JV partner of OSC's predecessor entity (PPG Industries Taiwan Ltd., 1983–2003) and current global silica/coatings producer. Comparable through overlapping silica technology heritage and overlapping tire/rubber/coatings customer base.
• Tokuyama Corporation: Japanese diversified chemical manufacturer and OSC's strategic investor since 2004; produces its own precipitated silica and specialty chemicals. Comparable through overlapping product lines and customer base, while serving as both a backer and a competitor.

Direct peers

• Cabot Corporation: U.S.-based performance chemicals company producing specialty carbons and silicas (CAB-O-SIL, CAB-O-SPERS) for rubber, battery, and industrial applications. Comparable to OSC across reinforced rubber and battery separator silica markets.
• Solvay (now Syensqo): Specialty silica producer (Zeosil, Tixosil) with strong positions in tire and oral-care applications. Direct competitor to OSC across the same precipitated silica grade families and customer segments.
• Wacker Chemie: German specialty chemical company producing HDK fumed silica and precipitated silica grades for silicone rubber, tire, and industrial applications. Directly competes with OSC in silicone-rubber and high-purity silica markets across Asia.
• Imerys: France-based global industrial minerals group producing functional silica and mineral additives for rubber, paint, food, and personal care. Direct competitor to OSC across non-tire specialty silica applications.
• Evonik Industries: Global specialty chemicals major producing precipitated silica under the SIPERNAT and ULTRASIL brands, serving tire, rubber, food, and personal care customers. Closest direct competitor to OSC's core precipitated silica business and benchmark for HDS-grade green-tire silica.

Regional players

• Quechen Silicon Chemical: Chinese producer of precipitated silica focused on tire, rubber, and footwear applications. Directly comparable to OSC's commodity precipitated silica offering and a key Asia-based competitor in the same regional tire supply chain.
• Sinochem Quanzhou Silica: China-based precipitated silica and silicate manufacturer serving regional tire, rubber, and detergent markets. Comparable to OSC across sodium silicate and silica product lines within an overlapping Southeast Asia and Greater China trade corridor.
• Tongxiang Hengsheng Silica: China-based regional precipitated silica producer serving domestic tire and footwear manufacturers. Comparable to OSC's mid-tier silica offering and a representative of the lower-cost Asian capacity base that pressures commodity-grade pricing.
