In 2023–2024, the United States and Germany were the leading exporters of Isobutylene (CAS 115-11-7), accounting for a combined majority of global export value, while China, South Korea, and Mexico ranked as the top importers. Trade volumes remained relatively stable across major corridors, though regional shifts in Isobutylene prices have coincided with increased import demand from Southeast Asian polymer producers.
Recent Market Intelligence on IsobutyleneI. Price Trends1. **Domestic Market**: Recently, the domestic market price of isobutylene has shown a slight upward trend with minor fluctuations. The mainstream transaction price in the East China region is between 12,000 and 12,500 RMB/ton, an increase of approximately 300 to 500 RMB/ton compared to the same period last month; the price in the South China region is between 12,200 and 12,700 RMB/ton, with a similar increase to that in East China.2. **International Market**: International isobutylene market prices remain relatively stable. Prices in the United States are between 1,600 and 1,700 USD/ton (FOB), while prices in Europe are between 1,550 and 1,650 EUR/ton (FOB). Influenced by global energy price fluctuations and supply-demand relationships to a lesser extent, the overall fluctuation range is within 2%.II. Supply Situation1. **Domestic Capacity**: The operating rate of major domestic isobutylene production enterprises is maintained at around 75% to 80%. Some enterprises have experienced slight fluctuations in operating rates due to equipment maintenance or raw material supply issues. Regarding new capacity, there are no plans for large-scale new plant commissions in the near term.2. **Import Situation**: Import volumes remain relatively stable, with main sources of imports being the United States, Europe, and other regions. There have been no significant changes in recent import arrivals, resulting in minimal impact on domestic market supply.3. **Inventory Levels**: Domestic isobutylene inventories are at a moderate level. Inventories of some production enterprises have decreased slightly, while trader inventories remain relatively stable. As downstream demand gradually releases, inventories are trending toward further decline.III. Demand Situation1. **Downstream Industry Demand** - **Rubber Industry**: Isobutylene is a key raw material for producing butyl rubber. Recently, the operating rate of the rubber industry has increased, boosting demand for isobutylene. In particular, tire manufacturing enterprises, driven by the recovery of the automotive market and increased order volumes, have heightened demand for butyl rubber, thereby pulling up the market demand for isobutylene. - **Polyisobutylene Industry**: Polyisobutylene is widely used in lubricant additives, adhesives, and other fields. Recently, the operating rate of polyisobutylene production enterprises has remained stable, with no significant change in demand for isobutylene. - **Methyl Methacrylate (MMA) Industry**: Isobutylene is one of the raw materials for producing MMA, but the proportion of isobutylene demand in the MMA industry is relatively small. Recent significant fluctuations in MMA market prices have had limited impact on isobutylene demand.2. **Export Situation**: Domestic isobutylene exports are minimal, mainly directed to Southeast Asia and other regions. There have been no significant changes in recent export orders, resulting in minimal impact on domestic market demand.IV. Cost Factors1. **Raw Material Prices**: The primary raw material for isobutylene is C4 fractions. Recently, C4 fraction market prices have been minimally affected by international crude oil price fluctuations, remaining overall stable. However, in some regions, prices have risen slightly due to supply tightness, providing certain support to isobutylene production costs.2. **Energy Prices**: Domestic energy prices remain relatively stable, with no significant fluctuations in natural gas, electricity, and other prices, resulting in minimal impact on isobutylene production costs.V. Policies and RegulationsRecently, the state has not issued any policies or regulations directly related to the isobutylene industry. However, environmental protection policies continue to tighten, raising environmental requirements for isobutylene production enterprises. Some enterprises may need to increase environmental protection investments, which could impact their production costs and supply capacity to some extent.Analysis and Judgment1. **Supply Side**: The operating rate of domestic isobutylene production enterprises remains relatively stable. New capacity will not be released to the market in the short term, and import volumes show no significant changes, resulting in relatively stable overall supply. However, the slight decrease in inventories of some enterprises may have a certain impact on market supply.2. **Demand Side**: Increased demand from the rubber industry is the main driving factor, while demand from the polyisobutylene and MMA industries remains relatively stable. With the gradual recovery of downstream industries, market demand for isobutylene is expected to continue growing.3. **Cost Side**: Raw material C4 fraction prices are stable, and energy prices show no significant fluctuations, resulting in relatively stable cost support for isobutylene prices. However, the tightening of environmental protection policies may increase enterprise production costs, exerting certain upward pressure on prices.4. **Market Sentiment**: Recently, market participants have been relatively optimistic about the prospects of the isobutylene market. The purchasing enthusiasm of traders and downstream enterprises has increased, and the market trading atmosphere is relatively active.Forecast1. **Price Trends**: It is expected that isobutylene market prices will continue to show a slight upward trend with minor fluctuations in the short term. Prices in the East China region are expected to break through 12,500 RMB/ton, while prices in the South China region are expected to reach 12,700 to 13,000 RMB/ton. In the medium to long term, with the further release of downstream demand and relatively stable supply, prices are expected to remain at a high level.2. **Supply-Demand Relationship**: On the supply side, the operating rate of domestic production enterprises will remain stable, import volumes will show no significant changes, and market supply will be relatively sufficient. On the demand side, demand growth from the rubber industry will be the main driving force, while demand from the polyisobutylene and MMA industries will remain relatively stable, and overall market demand is expected to continue growing.3. **Risk Warnings**: Attention should be paid to the impact of international crude oil price fluctuations on raw material C4 fraction prices, as well as the impact of environmental protection policies on enterprise production and supply capacity. Additionally, changes in downstream industry demand may also have a significant impact on isobutylene market prices.
Isobutylene (2-methylpropene) is a colorless, highly volatile, flammable gas at ambient temperature and pressure, with a mild, gasoline-like odor; it is typically handled as a liquefied gas under moderate pressure and boils at −6.9 °C. It is an aliphatic olefin and a key C₄ hydrocarbon intermediate in petrochemical manufacturing. Isobutylene serves primarily as a precursor to butyl rubber, polyisobutylene, and methyl tert-butyl ether (MTBE), and is widely used in the synthesis of antioxidants, lubricant additives, and alkylate gasoline components. Its principal application areas include synthetic elastomers, fuel additives, adhesives, sealants, and specialty polymers.
Primarily used to produce diisobutylene, trimers, butyl rubber, and other polymers; also to produce antioxidants for foods, packaging, food supplements, and for plastics: Hatch, Pet. Refin. 39, No. 6, 207 (1960).
