Thiokol

Thiokol (variously Thiokol Chemical Corporation, Morton-Thiokol Inc., Cordant Technologies Inc., Thiokol Propulsion, AIC Group, ATK Thiokol; finally ATK Launch Systems Group before becoming part of Orbital ATK) was a U.S. corporation concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. Its name is a portmanteau of the Greek words for sulfur (θειον "theion") and glue (κολλα "kolla"), an allusion to the company's initial product, Thiokol polymer.
