Shallow Shell™ Technology Products

Purolite's Shallow Shell technology or SST®, is designed to improve softening and demineralization performance. Our R&D and manufacturing teams perfected an advanced resin bead structure to increase regeneration efficiency, reduce leakage and fouling and conserve rinse and dilution water so that systems run better, with less expense and enhanced performance.

• Requires less regenerant chemicals to achieve equal or better operating performance

• Provides savings in rinse and dilution water

• Reduces leakage at same regenerant dosage as traditional resin

• Suitable for co-flow, counter-flow and packed bed systems

• Supports ISO 14001:2015 initiatives toward environmental management and impact; uses less chemical regenerant and generates less waste

Product	Type	Ionic Form	Dry Weight Capacity (min.) (eq/kg)	Moisture Retention (%)	Specific Gravity	Reversible Swelling (max. %)	Remarks & Applications
SSTC60	Strong Acid Cation Gel Polystyrenic	Na⁺	*3.8	38−46	1.20	Na⁺→H⁺ 8	Also available in uniform particle size as Shallow Shell SSTPPC60. Increased resistance to iron and manganese fouling over standard softening resins.
SSTC80	Strong Acid Cation Gel Polystyrenic	Na⁺	*4.0	42−48	1.20	Na⁺→H⁺ 7	Primarily used for softening high TDS water at elevated temperature.
SSTC104	Weak Acid Cation Gel Acrylic	H⁺	*5.5	36−44	1.17	H⁺→Ca²⁺ 20 H⁺→Na⁺ 60	Primarily used for high TDS softening. High efficiency and less susceptible to heavy metal fouling. Very low rinse water requirements.
SSTA63	Type II Gel Polystyrenic Strong Base Anion	Cl⁻	*2.6	37−45	1.12	Cl⁻→OH⁻ 15	Primarily used for high performance demineralization. High operating capacity and good silica removal.
SSTA64	Type I Gel Polystyrenic Strong Base Anion	Cl⁻	*2.7	43−51	1.08	Cl⁻→OH⁻ 20	Primarily used for high performance demineralization. Excellent silica removal.

NOTE: * SST products typically have equal to higher operating capacities than standard grade ion exchange resin based on multiple cycles.
