DOWEX^® Ion Exchange Resins

DOWEX^® resins are made of spherical particles. The benefit for the user is a highly efficient exchange process, due to optimal flow-through kinetics because of the round (spherical) particles.

We offer a broad range of DOWEX^® ion exchangers (anion and cation) featuring small particle sizes and narrow particle size distributions (50 - 100 mesh, 100 - 200 mesh, 200 - 400 mesh). In addition, analytical grade qualities of DOWEX^® resins are available. These products are processed from original DOWEX^® (»practical grades«) resins, following a proprietary procedure developed by us.

DOWEX^® 1 - anion exchangers of type I, strongly basic:  
A series of gel ion exchangers based on styrene-DVB-copolymerisates of type I. Refers to U.S. Food Additive Regulations, Ref. 1.21.1148

Supplied form of all DOWEX^® anionic resins:
pract. grade = Cl^- form
analytical grade = Cl^- form

Maximum working temperature for all DOWEX^® anion resins listed:
100 °C for Cl^- form
60 °C for OH^- form

For other counter ions please inquire for special bulk production.

DOWEX^® 50 W - cation exchangers, strongly acidic:
Spherical beads, sulfonated polystyrene/ DVB matrix.

Supplied form of all DOWEX^® 50 W resins:
pract. = H⁺ form
analytical grade = Na⁺ form

Maximum working temperature for all DOWEX^® cation resins listed:
120 °C for Na⁺ form
120 °C for H⁺ form

For other counter ions please inquire for special bulk production.
