Types segmentation captures the purity grades and formulation variants that influence both price and performance. The core category is Pure Electronic Grade SF6, defined by a minimum 99.9 % purity and stringent moisture limits (<10 ppm), meeting IEC 61800‑3 standards for critical power equipment. A sub‑type, Ultra‑High‑Purity SF6, exceeds 99.99 % purity and is reserved for ultra‑sensitive applications such as aerospace‑grade switchgear where trace contaminants can precipitate premature failure. Recycled SF6 constitutes a growing segment, wherein used gas undergoes distillation and moisture removal to reclaim purity levels comparable to virgin product, offering cost advantages while addressing environmental regulations. Finally, Blended Gas formulations combine SF6 with alternative insulating gases (e.g., CO₂, N₂) to reduce global‑warming potential; these blends are classified by the proportion of SF6 retained, typically 20‑40 %. Each type contributes distinctively to the market size, with Pure Electronic Grade SF6 dominating (>80 % of volume) due to its established reliability, while recycled and blended variants capture incremental growth driven by sustainability mandates.
