overview

INITIA® 310 is a high actives and high purity sulfonated copolymer that is effective for control of calcium phosphate and iron and is highly effective for the dispersion of silt, sludge and other inorganic particulates in process water applications. INITIA® 310 is extremely effective for cooling water applications where phosphate, iron, and general scale and solids control are required.  Additionally, INITIA® 310 can be utilized for iron transport, sludge conditioning, and solids control in low to medium pressure boiler water applications.  INITIA® 310 complies with 21 CFR 173.310 for boiler water additives where steam may contact food and has been independently verified to be compliant with TSCA, NSF® G5, G6, G7 and Kosher requirements.

calcium phosphate stabilization

INITIA® 310 contains a high level of sulfonate functional groups which provide more effective stabilization of calcium phosphate than competitive polymers. Compared to standard copolymers, INITIA® 310 contains 80% more sulfonate functionality. This is evidenced by comparative phosphate stabilization laboratory tests as shown in figure 1.

Further, INITIA® 310 is produced by a process that yields a high purity and active polymer. Because of this, INITIA® 310 yields improved performance versus polymers that also contain high levels sulfonate functional groups. Figure 2 shows INITIA® 310 compared to a competitive polymer with the same molar concentration of sulfonated monomer but with lower activity and purity.

iron stabilization

The increased level of sulfonate functionality in INITIA® 310 and optimized molecular weight are key design characteristics for effective stabilization of transition metals such as iron. INITIA® 310 was evaluated for iron stabilization using 2 ppm Fe2+ at 70 °C for 18 hours.

thermal stability

INITIA® 310 is an effective tool for use in boiler applications for iron transport, hydroxyapatite control, and general solids dispersion.INITIA® 310 was evaluated using Thermogravimetric analysis (TGA) to demonstrate the thermal stability of the polymer. Figure 3 shows that INITIA® 310 substantially retains its integrity up to 270° C which equates to about 800 psi in boiler applications. Based upon traditional uses of similar copolymers, it is recommended that the use of INITIA® 310 is limited to 600 psi or below.
