Performance Intermediates

Arxada’s AGU (Acetylene Generation Unit) in Visp, Switzerland is the backbone of a comprehensive, fully backward integrated chemical network (Verbund). Originating from this enabling technology we offer a variety of basic chemicals and performance intermediates based on special technologies like Hydrocyanic Acid- (HCN), Cyanogen chloride-, Acetylen-, Ethylene- and Ketene/Diketene- chemistry.



Pyromellitic Anhydride (PMDA) is produced in Nanjing, China and is a raw material for heat-resistant polyimide resins, films and coatings. PMDA is mainly applied as an intermediate for polyimide films as well as polyimide-based composite materials in flexible printed circuit boards, tape automated bonding, magnetic wire insulation, and other high-performance applications. It is also used as a curing agent for epoxy resins used in molding powders (to produce components for seal rings, thrust washers, special gaskets or thermal and electrical insulators), adhesives and coatings.
