Thai Rayon Public Company

What Thai Rayon Public Company does

Thai Rayon Public Company Limited is a Thailand-based B2B manufacturer of viscose staple fibre (VSF) and a high-purity sodium sulphate by-product, and is Thailand's first and only VSF producer. Incorporated in 1974 and listed on the Stock Exchange of Thailand since 1984, the company operates a single integrated manufacturing complex in Ang Thong Province with an annual VSF capacity of 151,000 tons across five production lines, supported by an on-site Carbon-di Sulphide plant commissioned in 2008. Thai Rayon is majority-owned by the Aditya Birla Group, a US$41 billion Fortune 500 conglomerate whose Birla Cellulose brand is the global marketing platform under which the company's fibres are exported to more than 30 countries, with approximately 90% of output sold internationally.

The company's product portfolio consists of standard Viscose Staple Fibre, the next-generation Birla Modal fiber positioned as a premium soft-handle offering, and sodium sulphate sold into detergent, glass, textile, and chemical-processing markets. Production is based on chemical processing of cellulose pulp dissolved and extruded through spinnerets — a capital-intensive, process-engineering-driven operation rather than a digital or software-driven model. The firm holds ISO 14001 environmental management certification and is run from a Bangkok head office (Pathum Wan) with the manufacturing footprint concentrated in a single Ang Thong site.

Revenue is generated through direct B2B sales to global textile manufacturers and industrial chemical buyers under quote-based, non-publicly-disclosed pricing tied to volume, fiber specification, and delivery terms. The company employs between 501 and 1,000 staff and reported FY2024 revenue of 12.3 billion Thai Baht. Customer acquisition and retention rely on the trust conferred by the Birla Cellulose / Aditya Birla Group brand, sustained product quality over five decades, and ESG credentials required by large apparel supply chains, rather than on direct marketing, software channels, or third-party distribution intermediaries.

Expansion highlights4 records

Direct peers

• Hi-Tech Fiber Group: Chinese viscose staple fiber producer with multi-line manufacturing facilities serving textile mills across Asia. Comparable regional competitor with similar commodity-grade VSF focus and export orientation.
• Tangshan Sanyou Chemical Industries: Chinese integrated producer of viscose staple fiber and soda ash (a downstream of sodium sulfate). Directly comparable as a large-scale VSF manufacturer with integrated chemicals by-products, competing in similar Asian textile markets.
• Acelon Chemicals & Fiber Corporation: Taiwan-based producer of viscose rayon filament and staple fiber serving Asian textile manufacturers. Smaller but directly comparable cellulosic fiber competitor with similar product portfolio and export-oriented B2B model.
• Sateri: China-based, world's largest viscose staple fiber producer owned by Royal Golden Eagle Group, operating multiple large-scale VSF mills. Direct competitor serving the same global textile mill customers as Thai Rayon with comparable commodity and specialty cellulosic fiber offerings.
• Lenzing AG: Austrian specialty fiber manufacturer producing viscose, modal, and lyocell staple fibers for the global textile and nonwoven markets. Direct competitor to Thai Rayon in man-made cellulosic fibers, with similar product portfolio (VSF, Modal) and overlapping global B2B textile customer base.
• Aditya Birla Grasim Industries (Cellulosic Fibres): Indian-listed parent entity that operates the global Birla Cellulose VSF platform alongside Thai Rayon, including flagship plants in India and Indonesia. Highly comparable as the same group business, sharing technology, brand, and customer pipeline.
• Jiangsu Aoyang Technology Co. China-based lyocell and viscose fiber producer expanding into next-generation cellulosic fibers. Comparable emerging supplier of regenerated cellulosics competing with Thai Rayon's VSF and Birla Modal offerings.

Broad incumbents

• Celanese Corporation: US-based acetyls and engineered materials producer that historically operated cellulose acetate fiber assets. Broad incumbent in acetyl chain with adjacent cellulosic technology relevant to viscose, though not a primary VSF competitor to Thai Rayon.
• Eastman Chemical Company: Large US specialty chemical company whose fibers segment historically included cellulose acetate tow and other cellulosic products. Overlaps with Thai Rayon in cellulosic chemistry but competes only partly and across a much broader chemicals/materials portfolio.

Others

• Aditya Birla Group (Birla Carbon): Sister Aditya Birla Group company operating a Carbon-di Sulphide plant at the same Ang Thong site as Thai Rayon and partnering on CSR initiatives. Important ecosystem relationship given the shared CS2 feedstock link into Thai Rayon's viscose process.
