Sphelite ASD-35 Primary Amine Resin

Sphelite ASD-35 is a primary amine functionalized macroporous resin designed for biogas upgrading and biomethane purification. Its crosslinked polystyrene structure selectively adsorbs CO₂ from raw biogas, raising methane purity while resisting the humidity and trace contaminants found in digester and landfill gas.
