2025 年,全球二甘醇 (DEG) 市場呈現穩定成長態勢,市場規模達 52.1 億美元。根據報告數據,預計 2026 年市場規模將達到 54 億美元,並在 2034 年進一步成長至 73.5 億美元。這一成長軌跡凸顯了二甘醇 (DEG) 在聚酯樹脂、溶劑、防凍劑配方和化學中間體等領域持續重要的工業應用價值。 2025 年,亞太地區憑藉強大的工業生產能力和成本效益高的製造生態系統,以 74% 的市佔率主導全球市場。
二甘醇 (DEG) 是一種無色、無味、易吸濕的有機化合物,可與水完全混溶。它作為溶劑、增塑劑、保濕劑和化學中間體的多功能性使其廣泛應用。該化合物在不飽和聚酯樹脂的生產中發揮關鍵作用,而不飽和聚酯樹脂廣泛應用於建築材料、汽車零件、船舶複合材料、塗料和黏合劑等領域。除了樹脂之外,二甘醇還用於煞車油、液壓系統、冷卻液、化妝品和潤滑劑,確保了其在各行業的多樣化和強勁需求。
二甘醇 (DEG) 市場趨勢
影響市場發展的關鍵趨勢之一是生物基和永續原料的日益普及。生物基二甘醇 (DEG) 由甘蔗、玉米和甘油(一種生質柴油產品)等再生資源生產。在巴西和印度等甘蔗資源豐富的國家,生產再生二甘醇的經濟效益日益凸顯。生物乙醇轉化技術的進步提高了產率,使大規模生產成為可能。像 Braskem 和 Sojitz 這樣的公司正在投資再生乙二醇的生產能力,進一步推動了這項轉變。環境法規、綠色認證以及對低排放化學品日益增長的需求,都在強化生物基二甘醇的長期地位。
市場動態
市場驅動因素
不飽和聚酯樹脂的重要作用仍然是二甘醇 (DEG) 市場的主要驅動因素。這些樹脂是建築、汽車和船舶行業使用的纖維增強塑膠的關鍵材料。亞太地區(尤其是中國和印度)基礎設施的快速發展,以及對輕質、耐用和經濟高效材料的日益增長的需求,持續支撐著二甘醇的消費。熱固性樹脂在汽車領域的廣泛應用,進一步鞏固了二甘醇在全球工價值鏈中的重要性。
市場限制
儘管二甘醇具有工業價值,但其高毒性仍是一個重大限制因素。接觸二甘醇會導致嚴重的腎臟和神經系統損傷,在極端情況下甚至會導致致命中毒。由於缺乏特效解毒劑且早期檢測困難,因此,尤其是在製藥和消費品應用領域,二甘醇受到嚴格的監管。這些安全隱患限制了其在敏感領域的應用,並給生產商帶來了合規方面的挑戰。
市場機會
新興經濟體的快速工業化帶來了強勁的成長機會。中國、印度和東南亞地區基礎設施、城市住房、交通和製造業的擴張,正在增加對二甘醇基樹脂、塗料、黏合劑和增塑劑的需求。政府對能源、交通運輸和住房項目的投資正在支撐消費成長,而本地製造能力的提升則正在推動市場的長期擴張。
市場挑戰
原料價格波動,尤其是與原油市場相關的環氧乙烷價格波動,仍是一項重大挑戰。原料成本的快速上漲會影響生產計劃、獲利能力和價格穩定性。儘管一些製造商正在努力實現供應來源多元化並提高營運效率,但價格波動仍影響著市場的穩定性。
按應用領域劃分,聚酯樹脂合成佔據主導地位,這得益於其在建築、汽車和船舶等行業的纖維複合材料中的廣泛應用。防凍液混合物市場也呈現穩定需求,這得益於全球汽車保有量的增長以及日益嚴格的汽車性能標準,這些標準要求高效的冷卻和熱傳遞解決方案。
亞太地區預計將引領二甘醇 (DEG) 市場,在基礎建設、汽車生產和大規模聚酯製造的推動下,2025 年市場規模將達到 38.7 億美元,2026 年將達到 40.2 億美元。

The global diethylene glycol (DEG) market demonstrated stable expansion in 2025, with a recorded market size of USD 5.21 billion. According to the report year data, the market is projected to reach USD 5.40 billion in 2026 and further expand to USD 7.35 billion by 2034. This growth trajectory highlights the sustained industrial relevance of diethylene glycol across polyester resins, solvents, antifreeze formulations, and chemical intermediates. In 2025, Asia Pacific dominated the global market with a 74% market share, supported by strong industrial output and cost-efficient manufacturing ecosystems.
Diethylene glycol is a colorless, odorless, and hygroscopic organic compound that is fully miscible with water. Its versatility as a solvent, plasticizer, humectant, and chemical intermediate underpins its wide adoption. The compound plays a critical role in the production of unsaturated polyester resins, which are extensively used in construction materials, automotive components, marine composites, coatings, and adhesives. Beyond resins, DEG is also used in brake fluids, hydraulic systems, coolants, cosmetics, and lubricants, ensuring diversified and resilient demand across industries.
Diethylene Glycol Market Trends
A major trend shaping the market is the rising adoption of bio-based and sustainable raw materials. Bio-based diethylene glycol is produced from renewable sources such as sugarcane, corn, and biodiesel byproducts like glycerol. Countries such as Brazil and India, with abundant sugarcane availability, are witnessing increasingly competitive production economics for renewable DEG. Advancements in bio-ethanol conversion technologies have improved yield efficiency, making large-scale production more viable. Investments by companies such as Braskem and Sojitz in renewable ethylene glycol capacity support this shift. Environmental regulations, green certifications, and demand for low-emission chemicals are strengthening the long-term role of bio-based DEG.
Market Dynamics
Market Drivers
The critical role of unsaturated polyester resins remains the primary driver of the diethylene glycol market. These resins are essential in fiber-reinforced plastics used in construction, automotive, and marine sectors. Rapid infrastructure development and the growing preference for lightweight, durable, and cost-effective materials in Asia Pacific, particularly in China and India, continue to support DEG consumption. Expansion of thermosetting resin usage in automotive applications further reinforces DEG's importance within the global chemical value chain.
Market Restraints
Despite its industrial value, diethylene glycol's high toxicity poses a significant restraint. DEG exposure can lead to severe kidney damage, neurological disorders, and, in extreme cases, fatal poisoning. The absence of a specific antidote and difficulties in early detection have resulted in strict regulatory controls, especially for pharmaceutical and consumer applications. These safety concerns limit its use in sensitive sectors and create compliance challenges for manufacturers.
Market Opportunities
Rapid industrialization in emerging economies presents strong growth opportunities. Expanding infrastructure, urban housing, transportation, and manufacturing activities in China, India, and Southeast Asia are increasing demand for DEG-based resins, coatings, adhesives, and plasticizers. Government investments in energy, transport, and housing projects support higher consumption, while rising local manufacturing capabilities encourage long-term market expansion.
Market Challenges
Raw material price volatility, driven by fluctuations in ethylene oxide prices linked to crude oil markets, remains a key challenge. Sudden increases in feedstock costs impact production planning, profitability, and pricing stability. Although some manufacturers are diversifying suppliers or improving operational efficiency, price instability continues to affect market consistency.
By end-use, polyester resin synthesis holds the dominant share due to its extensive use in fiber composites for construction, automotive, and marine applications. The antifreeze blending segment also shows steady demand, supported by the global vehicle fleet expansion and stricter automotive performance standards that require efficient cooling and heat-transfer solutions.
