noun

[mass noun] Chemistry
  • The property of becoming less viscous when subjected to an applied stress, shown for example by some gels which become temporarily fluid when shaken or stirred.
    More example sentences
    • A very desirable property in many applications is thixotropy, in which the material behaves as a gel or very viscous liquid at rest or subject to mild shear, but flows freely when subjected to a larger shear.
    • When cold it is difficult or impossible to ‘shake out’ the stiffening due to enhanced thixotropy.
    • Another property of muscles that increases resistance is thixotropy.

thixotropic

Pronunciation: /ˌθɪksəˈtrəʊpɪk, -ˈtrɒpɪk/
adjective
More example sentences
  • These systems are called thixotropic and are characterized by a difference in viscosity, depending on the speed at which the shear force is applied.
  • Its use in stabilizer systems is advantageous because it exhibits thixotropic rheological properties, requiring little change in processing conditions while providing stability to the finished product.
  • Another advantage of the theory is that it provides a possible explanation for an important quantitative difference between the thixotropic properties of relaxed and contracting fibers, the rate of stiffness recovery.

Origin

1920s: from Greek thixis 'touching' + tropē 'turning'.
