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 proprietory 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:

• 60 °C (140 °F) for Cl- form
• 40 °C (104 °F) 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

For other counter ions please inquire for special bulk production.
