Abstract:

The viscosities of three liquids used as ingredients of plastic propellant have been measured at room temperature, as a function of strain-rate, by parallel plate plastometry. The liquids were a Vistanex LM, a polyisobutene with falling-sphere viscosity at very low shear-rates of about 100 kPa s 10 to the 6th power poise, b a mixture of polyisobutene, plasticiser and surfactants known as PSB, used as the binder for many propellant formulations, and c an unplasticised mixture of polyisobutene with surfactants, known as USB, similar to another propellant binder.
