New Method of Tackiness Testing

 Tackiness

  

Falex Application Lab new method :

 

State of the art Tackiness testing

 

After some initial trials and a lot of brainstorming, we now propose a correlation between the 'finger test' field experience of tackiness of a grease (the thread formation) and a lab-based repeatable and reproducible force measurement.

 

The lab method allows the measurement of pull-off force of a ball pressed into a grease, as well as the resistance against further pulling apart, while treads form.

 

As speed of separation plays a critical role in the thread formation, a speed mapping of the pull-off force is used to map the properties of a grease.
