Mesh to MM / Micron Conversion for Sieve SIzes:

Mesh sizes are used to determine sizing of our Graphite Powder - which are corresponded to sizes in mm or micron.


Mesh sizes are the number of openings in 1 sq. inch of the screen i.e. a 4 - mesh screen would have 4 openings per sq inch. A 200 mesh would have 200 such openings per sq inch. 


Minus (-) in a Mesh Size indicates that all material shall pass through that Mesh and Poisitive/Plus(+) in a Mesh Size indicates all material which is Retained or Doesn't pass through that mesh. 

i.e. -200 mesh indicates all material passes through 200 mesh and +200 mesh indicates all material is retained on -200 mesh.
