EVALUATION OF PFG ADDUCTS
Abstract
The evaluation of three perfluoroguanidine derivatives prepared by Esso Research Company was carried out using an NF binder system. P-FABDE, FA- TNENE, and FA-PETRIN were added to an NFPA-acrylic acid copolymer/TVOPA binder in varying amounts. A propellant containing 13% P-FABDE proceeding from burning to explosion at pressures of 400 psi and above. High speed motion pictures of burning propellants containing P-FABDE and FA-TNENE showed subsurface combustion of particles, build-up of incandescent streamers on the surface and rate increase through a wormholing or filled void process. Gas voids were produced during the curing reaction of propellants containing over 3% FA-TNENE. Processing difficulties were encountered using FA-PETRIN as plasticizer in place of TVOPA. Some increase in burning rate was obtained with P-FABDE and FA-TNENE but other considerations, i.e., sensitivity, stability, processing and handling, indicate other methods and materials may be more satisfactory.
