What is the particle size and micron size for DOW™ ion exchange resins?
Standard ion exchange resins have mean particle sizes of 500 – 800 microns. UPS (Uniform Particle Size) ion exchange resins have a narrow particle size distribution while standard Gaussian resins range from 300 – 1200 microns. The bead size varies with the product. Each product information sheet provides either a mean bead size or a bead size distribution. Dow also carries a line of fine mesh resins, available in the 200 – 400, 100 – 200, and 50 – 100 mesh size. Mesh size is the number of openings in a square inch of a screen or sieve, or the square of the number of strands of wire per lineal inch. Standard U.S. mesh screen No. 16, for example, equates to a 1.19 mm (millimeter) particle diameter and mesh size No. 100 is 0.15 mm particle diameter . Most DOW Ion Exchange Resin technical data sheets that give the mean particle size and/or range.
