Sphelite ASD-35 Primary Amine Resin Direct Air Capture for Ambient CO2 Adsorption

Sphelite ASD-35 Primary Amine Resin

Sphelite ASD-35 is a primary amine functionalized macroporous resin tailored for direct air capture (DAC) and ambient CO₂ adsorption. Its crosslinked polystyrene backbone provides high mechanical strength and a large surface area, supporting repeated capture and release cycles with low regeneration energy.
