Western Electrochemical Co


AMPAC’s perchlorate business, Western Electrochemical Co (WECCO), is a worldwide leader in the production of ammonium perchlorate (AP) and other perchlorate chemicals and derivatives.


The company has supplied AP for use in aerospace, national defense programs and commercial applications for more than 40 years.


AP is the leading oxidizing agent for solid propellant rockets, booster motors and missiles that are used in space exploration, commercial satellite transportation and national defense programs. A significant number of existing and planned space launch vehicles use a solid propellant and thus depend, at least in part, upon our AP.


WECCO is the anchor operation of AMPAC’s Utah Production Facility. This facility is ISO 9001-2008, ISO 14001:2004, and OHSAS 18001:2007 certified.
