Brabender Plastograph
Encyclopedia
The plastograph, or Brabender plastograph, is a device for the continuous observation of torque
in the shearing
of a polymer
with a range of temperatures and shear rates. The generic device records lubricity
, plasticity
, scorch
, cure
, shear
and heat stability.
Perhaps the most popular use of the plastograph is its use in baking where it is known as a Farinograph
.
It was designed by Carl Wilhelm Brabend and produced by Brabender Industries, founded in 1923.
Torque
Torque, moment or moment of force , is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist....

Shearing (physics)
Shearing in continuum mechanics refers to the occurrence of a shear strain, which is a deformation of a material substance in which parallel internal surfaces slide past one another. It is induced by a shear stress in the material...

Plasticity (physics)
In physics and materials science, plasticity describes the deformation of a material undergoing non-reversible changes of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the...

Farinograph
In Baking, a Farinograph measures specific properties of flour. It was first developed and launched in 1928 Brabender History. The Farinograph is used as a tool to measure shear and viscosity of a mixture of flour and water. The primary units of the farinograph are Brabender Units, an arbitrary...
