Top 10 Companies in the 1,3,5‑Trioxane (CAS 110‑88‑3) Market (2026): Market Leaders Powering Global Demand

MARKET INSIGHTS

Global 1,3,5‑Trioxane (CAS 110-88-3) market size was valued at USD 620.4 million in 2025. The market is projected to rise from USD 651.2 million in 2026 to USD 1,024.7 million by 2034, reflecting a compound annual change of 5.8% over the forecast period.

1,3‑5‑Trioxane, also known as trioxane or metaformaldehyde, is a cyclic trimer of formaldehyde with the molecular formula C₃H₆O₃. It is a white, crystalline solid that offers a stable and safer alternative to gaseous formaldehyde in a range of industrial applications. The compound is primarily employed as a precursor in the production of polyoxymethylene (POM), a high‑performance engineering thermoplastic, and also serves as a solid‑fuel tablet, a chemical intermediate in resin synthesis, and in the formulation of disinfectants and pharmaceutical compounds.

Demand is steadily increasing, driven by the need for POM engineering plastics across automotive and electronics sectors, where lightweight, high‑strength materials are prized. Growing industrial activity in Asia‑Pacific—particularly in China and India—continues to accelerate consumption of trioxane as a key chemical building block. Leading producers such as Shandong Yuanli Science and Technology Co., Ltd., Lanxess AG, and Tokyo Chemical Industry Co., Ltd. maintain a prominent presence in the global supply chain, supporting both bulk industrial and specialty‑grade demand segments.
