Absolute filtration rating
The diameter of the largest solid spherical particle that will pass through a filter under specified test conditions. This is an indication of the largest opening in the filter cloth.
Retention of liquids in the bulk of the fabric where the liquid is retained by filling up void spaces, i.e. pores of the fiber, between fibers in a yarn and between yarns in the fabric.
Glue for affixing the mesh to the screen printing frame. Mostly used are two component adhesives, but there are also rapid- and UV-glues available
Air flow/air permeability
Measure of the amount of air that flows through a filter – a variable of the degree of contamination, differential pressure, total porosity, and filter area. Expressed in ft3/min/ft2 or l/min/cm2 at a given pressure.
Material that minimizes static charge generation, provides 'controlled' static charge dissipation, or both.
See Mesh Opening
Reduction of the signal power or field strength as a function of distance through a material. Also refers to shielding effectiveness.
Vessel for high steam pressure heating of materials. Used for sterilization and other applications.
