American specialty chemicals company (NYSE: CBT, HQ Boston MA; ~$4B revenue); Cabot Norit activated carbon division is world's largest producer of activated carbon/activated charcoal for gas purification, water treatment, and pharmaceutical applications. In helium PSA (Pressure Swing Adsorption) purification plants, Cabot Norit activated charcoal beds at cryogenic temperatures adsorb trace impurities (neon, hydrocarbons, trace organics) from raw helium streams. Cabot Norit's activated carbon is simultaneously used in: helium plant gas purification, municipal water treatment (removing chlorine, THMs, and pharmaceuticals), air purification masks (same activated charcoal in military gas masks and HVAC filters), and pharmaceutical drug purification (decolorization of pharmaceutical intermediates). The same activated charcoal that cleans hospital water systems also purifies the helium that cools MRI superconducting magnets.

Japanese specialty chemical company (TSE: 3405); produces Trosifol® PVB and SentryGlas® ionoplast interlayer films at Troisdorf, Germany (~22% global PVB share). UNIQUE STRATEGIC POSITION: Kuraray is simultaneously the world's LARGEST polyvinyl alcohol (PVA) producer — the primary raw material for all PVB production globally — and a competing PVB maker. Kuraray was the first company to commercially produce PVA in the 1950s (Japan) and operates 6 PVA plants (Japan x2, USA, Germany, Singapore). This means Kuraray supplies the key raw material to Eastman Chemical and Sekisui Chemical while competing against them in PVB film. SentryGlas® ionoplast (5x tear strength vs. standard PVB, 100x rigidity) targets premium architectural and security glazing; celebrates 25+ years of market presence.
