丁二醇產能、產量、市場規模、平均價格及預測（2018-2034 年）

2025年全球丁二醇市場規模為104億美元，預計2034年將達290億美元，預測期內複合年成長率（CAGR）為11.5%。這一強勁成長主要得益於其在紡織、汽車、建築和電子等行業的應用不斷擴展。丁二醇是一種用途廣泛的化學中間體，用於生產四氫呋喃（THF）、聚丁烯對苯二甲酸酯（PBT）和生物分解聚合物（PBAT）等關鍵下游產品。對高性能材料、彈性纖維和工程塑膠的需求不斷成長，持續推動全球丁二醇消費量的成長。

丁二醇的需求分析

預計到2025年，全球BDO需求量將達到約290萬噸，過去五年複合年成長率（CAGR）為5%。市場供應趨勢受區域工業成長、原料價格波動和原油市場趨勢的影響。中國在全球供應中佔主導地位，總設備容量的62%。到2025年，中國的裝置容量將超過230萬噸，預計到2034年將成長近一倍，這主要得益於對下游PBAT、PBT和PTMEG生產的大量投資。儘管馬來酸酐價格上漲，但由於成本效益高，乙炔法仍是中國主要的生產流程。

BDO 的大部分消費與 THF 和 PBT 的生產有關，這兩種產品的消費量合計佔全球需求的 70% 以上。 THF 是生產氨綸纖維和 PTMEG（一種黏合劑的關鍵材料）的必需原料，而 PBT 因其高強度和熱穩定性而被廣泛應用於汽車、電氣和電子元件。 BDO 的其他應用包括聚氨酯 (PU)、γ-丁內酯 (GBL) 和其他特殊聚合物。特別是熱塑性聚氨酯 (TPU)，其在鞋類、建築和工業產品中的應用日益廣泛，並支撐著長期需求成長。

區域展望與生產變化

亞太地區持續引領全球BDO消費，主要得益於快速的工業化過程、具競爭力的生產成本以及強勁的下游需求。中國在生產和需求方面均保持著核心地位，而韓國和台灣等國家和地區也不斷擴大產能。相較之下，北美和歐洲等市場雖然成長放緩，但成長依然穩健，近年來也出現了一些產能合理化調整的現象。中東和拉丁美洲市場擁有長期發展潛力，各國政府都在積極推動產業多元化。

主要企業及近期趨勢

主要的BDO生產商包括BASF、中國石化、利安德巴塞爾、三菱化學、大連化學和亞什蘭。儘管生物基BDO的生產日益受到關注，但仍受到成本和規模的限制。近期產業動態包括山東如意關閉了其在美國的一座年產11萬噸的工廠，以及BASF石油公司關閉了其在馬來西亞的一座年產10萬噸的工廠，這兩家工廠都反映出某些地區存在供應過剩的情況。儘管有這些工廠關閉，但預計亞洲，特別是中國的新投資將重塑全球供應BASF。

生物分解性塑膠將塑造未來的需求。

PBAT產量的快速成長，尤其是在中國，預計將成為未來十年BDO市場的主要成長引擎。 PBAT是生物分解性塑膠，是軟包裝和一次性塑膠中低密度聚乙烯（LDPE）的永續替代品。光是在中國，PBAT產能就計畫超過7,000千噸，BASF、LG化學、紅大道、SK Geo Centric和Novamont等公司已宣布了大規模計劃。平均而言，生產1噸PBAT需要0.5噸BDO，這進一步鞏固了BDO在轉型永續性中的作用。

第15章附錄

The global Butanediol market was valued at USD 10.4 billion in 2025 and is projected to reach USD 29 billion by 2034, growing at a CAGR of 11.5% during the forecast period. This strong growth is being driven by expanding applications across the textile, automotive, construction, and electronics industries. BDO is a versatile chemical intermediate used in the production of important downstream products like tetrahydrofuran (THF), polybutylene terephthalate (PBT), and biodegradable polymers (PBAT). The increasing demand for high-performance materials, elastic fibers, and engineering plastics continues to push BDO consumption worldwide.

Butanediol demand analysis

The global BDO demand reached around 2,900 kilotons in 2025, with an average annual growth of 5% over the past five years. Market supply trends have been shaped by regional industrial growth, fluctuations in feedstock prices, and crude oil market dynamics. China dominates the global supply, accounting for 62% of total installed capacity. In 2025, the country had an installed capacity of over 2,300 kilotons, which is expected to nearly double by 2034 due to heavy investments in downstream production of PBAT, PBT, and PTMEG. The acetylene method remains the preferred production process in China, largely due to its cost efficiency amid rising prices of maleic anhydride.

A significant portion of BDO consumption is linked to the production of THF and PBT, which together account for over 70% of global demand. THF is essential in producing PTMEG, a key material for spandex fibers and adhesives, while PBT is used in automotive parts, electrical components, and electronics due to its high strength and thermal stability. Additional BDO applications include polyurethanes (PU), gamma-butyrolactone (GBL), and other specialty polymers. In particular, thermoplastic polyurethane (TPU) is seeing increased usage in footwear, construction, and industrial goods, supporting long-term demand growth.

Regional Outlook and Production Shifts

Asia-Pacific continues to lead global BDO consumption, driven by rapid industrialization, competitive production economics, and robust downstream demand. While China remains the core of both production and demand, countries like South Korea and Taiwan are also expanding capacities. In contrast, markets like North America and Europe are experiencing slower but steady growth, with some capacity rationalization observed in recent years. The Middle East and Latin America offer long-term potential as governments push for industrial diversification.

Key Industry Players and Recent Developments

Major BDO producers include BASF, Sinopec, LyondellBasell, Mitsubishi Chemical, Dairen Chemical, and Ashland, among others. Bio-based BDO production is also gaining attention, though still limited by cost and scale. Recent industry movements include the closure of Shandong Ruyi's 110 kiloton plant in the U.S., and BASF Petronas' 100 kiloton plant shutdown in Malaysia, both reflecting overcapacity in some regions. Despite these closures, new investments in Asia, especially China, are expected to reshape the global supply map.

Biodegradable Plastics to Shape Future Demand

The rapid expansion of PBAT production, especially in China, is expected to be a major growth engine for the BDO market in the coming decade. PBAT is a biodegradable plastic made from BDO and adipic acid, offering a sustainable alternative to low-density polyethylene (LDPE) in flexible packaging and single-use plastics. China alone has over 7,000 kilotons of PBAT capacity planned for development, with significant projects already announced by BASF, LG Chem, Red Avenue, SK Geo Centric, and Novamont. On average, 0.5 tons of BDO is required to produce 1 ton of PBAT, further reinforcing BDO's role in the sustainability transition.
