Isobutylene (2-Methylpropene, CAS: 115-11-7; UN 1055; Hazard Class 2.1 Flammable Gas) is a valuable olefin monomer from the C4 hydrocarbon chain. Two mainstream grades are widely available: 99.5% industrial grade and 99.9% polymer grade. Both can be supplied in 118L LPG-style cylinders with 50kg filling. However, they differ greatly in impurity control, reaction stability, and end-use suitability. Many buyers treat them as identical material, which may lead to polymerization failure, color deviation, and inconsistent product performance.

Since the second half of 2026, the global ethylene oxide market has been undergoing structural changes due to the combined effects of rising energy costs and a sharp decline in core production capacity. The continued rise in international oil prices has driven up raw material costs throughout the entire industry chain. Coupled with the unexpected shutdown of INEOS's 420,000-ton-per-year ethylene oxide plant in Bayport, Texas, the already weak global ethylene oxide supply and demand relationship has been rapidly disrupted. This change is spreading from North American production areas to other parts of the world, directly impacting the purchasing decisions of multiple downstream industries, including fine chemicals, semiconductor materials, new energy additives, and consumer chemicals.

Sulfur hexafluoride (SF₆, GWP₁₀₀ = 24,300, IPCC AR6) is one of the most potent greenhouse gases. China has put SF₆ formally on its national GHG inventory, and the 15th Five-Year Plan (2026–2030) clearly targets strengthened control over non-CO₂ fluorinated greenhouse gases.
The core trend: export procedures remain relatively open today, but supply conditions and compliance rules are expected to tighten in the coming years. While there is no immediate export ban yet, the era of simple, unrestricted bulk shipments of virgin SF₆ is likely nearing its end.

Sulfur Hexafluoride (SF₆) Q4 2026 Market Price Analysis & Limited-Time Bulk Promotion
Sulfur hexafluoride (SF₆) remains an indispensable specialty gas for high-voltage GIS switchgear insulation, arc quenching, and semiconductor plasma etching. As we enter Q4, many global buyers are closely watching SF₆ spot price movement and supply stability.
