Twin-Screw Extruder Safety Demonstration Tests

Abstract

Thiokol Corporation installed a Werner & Pfleiderer twin-screw extruder at the Longhorn Division in Marshall, Texas in 1988. A number of modifications to the installation have been made for safety and operational considerations. This paper will review the current installation and discuss some of the modifications and some of the processing results from operation of the system. The facility has been used to process live composite propellant in the mixer mode including casting of samples and test motors. The latest work includes processing in the mixer mode for applications such as infrared decoy flare compositions. The facility is considered a state-of-the-art installation for continuous processing with broad capabilities and special consideration for processing energetic materials.
