China and the United States are the leading exporters of Allene (CAS 463-49-0), accounting for the majority of global shipments in recent years, while Germany, Japan, and South Korea represent the largest importing markets. Trade volumes have remained relatively stable since 2022, with modest growth in European imports coinciding with upward pressure on Allene prices amid tightening supply from key Asian producers.
Allene Market Dynamics Report – Recent Commodity Market Intelligence
1. **Price Information**: As of June 27, 2026, the latest quotation for allene (GB standard, 99.9% purity) is RMB 1,800 per kilogram. The supplier is Shanghai Hanyang Chemical (850102) Co., Ltd., with delivery location specified as Shandong Province and Shanghai Municipality.
2. **Pricing Mechanism**: The Business Network Benchmark Price is derived from large-scale price data and the Business Network pricing model, serving as a transaction guidance price. It may be used to determine the settlement price on a specified date or the average settlement price over a designated period. The pricing formula is: Settlement Price = Business Network Benchmark Price × K + C, where K is the adjustment coefficient (accounting for factors such as credit terms and financing costs), and C represents the premium/discount (covering logistics costs, brand value differentials, regional price differentials, etc.).
Analysis and Assessment
1. **Supply-Demand Perspective**: Publicly available information does not directly specify recent changes in allene’s supply-demand fundamentals. However, considering the broader chemical market environment, the propylene industry chain currently faces supply-overhang pressure: global propylene capacity is projected to exceed 169 million metric tons in 2025, while demand stands at approximately 110 million metric tons. As allene is generated as a by-product/impurity during propylene production, its supply-demand dynamics may be indirectly influenced by the propylene market. Should the propylene supply surplus persist, it could affect allene’s production volume and market circulation—though the precise magnitude of this impact remains difficult to quantify directly.
2. **Price Trend Perspective**: With only a single-point price observation, accurate short-term price trajectory analysis for allene is infeasible. Nevertheless, reviewing overall olefin market trends (including propylene, polyethylene [PE], and polypropylene [PP]) from late 2025 through early 2026 reveals a pattern of initial decline followed by a low-level rebound. For instance, propylene prices fell from ~RMB 6,800/ton in July 2025 to ~RMB 5,718/ton in December 2025, then rebounded to ~RMB 6,421/ton in January 2026. Allene prices may likewise be affected by general market sentiment and upstream/downstream price fluctuations. However, due to its relatively small market scale, allene’s price volatility may exhibit distinct characteristics independent of broader olefin trends.
3. **Industry Competition Perspective**: Detailed competitive landscape data for the allene market is currently unavailable. Nonetheless, competition across the chemical sector remains intense. Against the backdrop of propylene-chain oversupply, enterprises are likely competing vigorously on cost control, product quality, and operational efficiency—factors that may indirectly influence allene production and pricing. For example, manufacturers seeking to lower propylene production costs may optimize their processes to minimize generation of impurities like allene, thereby reducing allene’s available market supply.
Forecast
1. **Short Term (1–3 months)**: Owing to insufficient historical supply-demand and price data, allene prices are expected to remain relatively stable in the near term—though minor fluctuations cannot be ruled out, driven by broader chemical market volatility or shifts in upstream/downstream product pricing. A pronounced change in propylene market fundamentals—such as further supply expansion or sudden demand growth—could transmit corresponding effects to allene pricing.
2. **Medium Term (3–6 months)**: As more market intelligence accumulates and broader chemical market trends become clearer, allene’s price direction may gradually emerge. If propylene oversupply intensifies, downward pressure on allene prices may materialize; conversely, improved propylene demand could support upward price movement. Additionally, evolving competitive dynamics and regulatory/policy adjustments may also exert meaningful influence on allene pricing.
3. **Long Term (6–12 months)**: Over the longer horizon, allene market development will largely hinge on the trajectory of the entire propylene value chain. Should propylene capacity growth decelerate and supply-demand balance gradually restore, the allene market may likewise stabilize. Moreover, continuous technological advancement—including novel production processes and efficiency-enhancing innovations—could reshape allene manufacturing economics and exert sustained structural influence on its pricing.
Allene (propa-1,2-diene) is a colorless, highly volatile, flammable gas at room temperature with a mild, chloroform-like odor; it has a boiling point of −34.5 °C and a melting point of −136 °C. It is classified as an aliphatic hydrocarbon and, more specifically, as a cumulated diene due to its two adjacent carbon–carbon double bonds. Allene serves primarily as a specialty chemical intermediate in organic synthesis, valued for its unique reactivity in cycloadditions, metal-catalyzed couplings, and as a building block for strained ring systems. Its principal applications are in the research and production of fine chemicals, including pharmaceuticals, agrochemicals, and advanced materials such as specialty polymers and optoelectronic compounds.
Organic intermediate.
Allene is colorless with a sweet odor. It is a flammable gas and may cause fl ash fi re at roomtemperature. Allene is the simplest member of the 1,2-diene class of compounds of hydrocarbonsof the aliphatic chemical family. It is a benzene and petroleum ether. Allenes arenot as stable as conjugated dienes or isolated dienes. Allene is slightly more strained thanthe isomeric methylactylene. Allene is chiefl y used in organic synthesis. It is incompatiblewith metals and oxidizing materials, therefore it is important to avoid copper and silverand their alloys when used under high pressure or temperature.
This chemical is included in Basic Chemicals. See more about what is Allene and Allene SDS information.
