What are Static Mixers?

Static mixers are a very simple way to mix two materials together. There are no moving parts just a series of elements joined together to cause two materials to disperse around them and blend into one material.

   Static = not moving
   Mixer = to mix something.

The process of pushing two liquids, usually adhesive, through a static mixer is what causes the mixing to occur. The mixing "element" or core remains stationary and the two materials fold around each element within a mixing tube to cause blending.

Static mixers are measured by the number of elements joined together. These elements are fastened inside a tube so material can flow in and around the elements. A longer static mixing tube equals more elements which equals greater mixing. There are a couple of factors that determine how to select a static mixer such as thickness of the adhesive (viscosity), back pressure, and amount of mixing required.
