1 Polymers as Binders and Plasticizers – Historical Perspective
نویسنده
چکیده
Ever since the introduction of nitrocellulose (NC) as an explosive fill in the 1850s, polymers have contributed considerably to advancements in the technology of both propellants and explosives. In addition to the specific instance of the use of NC polymer in explosive fills, applications of polymers have been most extensive in binders andplasticizers.Over the years,with thematurity of compositepropellant and polymer bonded explosive technology, diverse classes of polymers have been developed for binder applications, in order to meet the dual objectives of insensitivity and highperformance.This chapter focuses on thehistorical development of polymers for propellant and explosive formulations, particularly as binders and plasticizers.

Recent approach in the field of design and manufacture of the propellant and explosive has led to the use of energetic ingredients. Introduction of energetic plasticizers as a replacement of commonly used inert plasticizers is another approach to improve the energy level of propellants. In this meantime, energetic compound based on organic azids were attracting a lot of attention. The poor mech...

Use of plasticizers in the formulation of solid propellants especially double-base solid propellants is inevitable. Double base propellants are composed of nitrocellulose (NC) polymer. Plasticizers cause to increase flexibility, reduce viscosity and glass transition temperature. Energetic azido ester plasticizers are compatible with energetic binders in solid propellants. In this work, five dif...

Zein is one of the best biopolymer for edible film making and sugars are natural plasticizers for biopolymers. In this research, sugars (fructose, galactose and glucose) at three levels (0.5, 0.7, 1 g/g of zein) were used as plasticizers for zein protein films and their water vapor permeability (WVP), oxygen permeability (OP) and atomic force microscopy (AFM) topography were studied. The p...

Binder has a key role in the performance of composite propellants. The binders are classified into two neutral and high-energy categories. GAP is one of the most important energetic binders, but it has poor mechanical and thermal properties. The goal of this investigation is to improve the properties of GAP by copolymerizing it with polytetrahydrofuran. New energy triblock copolymer was synthes...
