Direct peers

• Indorama Ventures PCL: Indorama Ventures is the world's largest PET resin and polyester fiber/filament producer, with vertically integrated operations from PTA to filament yarn. It is a direct competitor across POY/FDY grades and recyPET, supplying automotive, apparel, and home textile customers globally with similar scale economics to Korteks.
• Hengli Petrochemical Co., Ltd. Hengli is one of China's largest integrated polyester producers with continuous polycondensation capacity comparable to Korteks's Berkun plant. It supplies filament yarn globally to apparel, home textile, and industrial customers, and represents the primary low-cost Asian competitor pressuring European polyester yarn margins.
• Far Eastern New Century Corporation: Far Eastern New Century is a Taiwan-based integrated polyester and textile conglomerate producing filament yarn, staple fiber, and downstream fabrics. It competes with Korteks in Asian and global polyester filament markets, including recycled (rPET) offerings and functional yarn segments like sportswear and automotive textiles.
• SASA Polyester Sanayi A.Ş. SASA is Turkey's other major polyester filament and staple fiber producer, headquartered in Adana. It competes head-to-head with Korteks in POY, FDY, and downstream textile yarn supply to Turkish and European customers. Both serve similar automotive, home textile, and apparel segments and operate continuous polycondensation lines at comparable scale.
• Shinkong Synthetic Fibers Corporation: Shinkong is a Taiwan-based polyester filament yarn and staple fiber producer with comparable POY/FDY product breadth. It supplies similar downstream segments (apparel, home textiles, automotive) and competes for European and global textile manufacturer accounts.

Broad incumbents

• Teijin Limited: Teijin is a Japanese materials group with polyester filament yarn, aramid fibers, and recycled fiber (Eco Circle) businesses. Its sustainability-focused and technical yarn products compete with Korteks's BIOLOOP, REBORN, and Hybrid lines in automotive, protective, and apparel segments across Europe and Asia.
• Toray Industries, Inc. Toray is a Japanese diversified materials conglomerate with significant polyester filament yarn production alongside fibers, films, and chemicals. Its functional and sustainable yarn lines (including recycled PET) overlap with Korteks's specialty offerings in automotive and sportswear, although Toray operates at much greater scale across multiple material categories.
• Reliance Industries Limited (Reliance Polyester): Reliance operates one of the world's largest polyester chains (Recron brand) with integrated PTA-to-yarn production. While a much broader petrochemical conglomerate, its polyester filament yarn business directly competes with Korteks in commodity POY/FDY and recyPET grades across global textile markets.
