Product Name:DOWEX 50WX8
English Name:DOWEX 50WX8
CAS No.:11119-67-8
Aliases:DOWEX 50WX8 strong acid cation exchange resin, Sulfonated polystyrene-divinylbenzene cation exchange resin
Physical Properties:Gel-type strong acid cation exchange resin, appearing as light yellow to amber spherical beads with sulfonic acid functional groups (-SO3H). Insoluble in water, acids, bases, and most organic solvents; thermally stable with a maximum operating temperature of approximately 120°C (H+ form). Wet bulk density is about 1.2-1.3 g/mL, and effective particle size is 0.4-0.6 mm.
Uses:Used for water softening, demineralization, and ultrapure water production, as well as for separation and purification of metal ions. It serves as an acidic catalyst in chemical production, promoting esterification, hydrolysis, and other reactions. Additionally, it is widely applied in pharmaceutical extraction, rare metal separation, and industrial wastewater treatment.
Technical Specifications:
Matrix is styrene-divinylbenzene copolymer with 8% crosslinking degree.
Functional group is sulfonic acid (-SO3H), classified as a strong acid cation exchange resin.
Ion exchange capacity ≥ 1.8 eq/L (wet volume).
Maximum operating temperature: 120°C for H+ form, 150°C for salt form.
Applicable pH range: 0-14.
