SEPLITE® Monojet™ MA9000 Ion Exchange Resin is a macroporous polystyrene type 1 strong base anion in uniform particle size.
It can be used to remove anions like silica. Due to the macroreticular structure, it has excellent resistance to mechanical and osmotic shock.
It is particularly recommended for use in applications such as condensate polishing where these resins can be operated at high flow rates.

Resins should be stored in sealed containers or bags where temperature was above 0℃ in dry conditions without exposure to direct sunlight.
Do not mix ion exchange resin with strong oxidizing agents; otherwise it will cause violent reactions.
In case of eyes contact with resins, rinse eyes immediately with plenty of water, and consult a specialist.
Material and samples must be disposed according to local regulations.
Dry polymers will expand when become wetted and may cause an exothermic reaction.
Spilled materials may be slippery.
