Relatively high molecular weight not sure but usually at room temperature is a solid, solid, solid, sometimes can be a liquid organic substances. Softening or melting temperature range, flows under external force, a shell-shaped rupture often. Broad sense refers to as polymers or oligomers of plastic substrates. Insoluble in water, soluble in organic solvents. Classified according to the source natural resins and synthetic resin according to its processing features are available in different thermoplastic resins and thermosetting resin.
DOWEX resin is an inseparable even mixed-bed resins. Ultrapure water polishing treatment phase can not be mixed bed regeneration in Silicon, boron, sodium, potassium, sulfate, chloride, zinc, iron and aluminium ions low ppb levels. This class cannot be used in mixed bed regeneration before replacing 2-3. UPW ions with high levels of resin has a conversion rate (95% minimum), excellent cleaning characteristics of electrical conductivity and TOC, and Super strength. Because it is a particle of 360 μm cation resin anion resin mixing and 590 microns, and keep it efficient dynamic performance and high capacity.
