ResinTech CG10-Na 10% Crosslinked Cation Exchange Resin, Na Form, 1 Cubic Foot
ResinTech CG10 is a sodium form 10% crosslinked gel strong acid cation resin. CG10 has high resistance to both thermal and chemical oxidation. ResinTech CG10 is intended for use in all industrial applications where physical and chemical durability are more important than chemical efficiency.
Features & Benefits
- 10% Divinylbenzene: Gives greatly increased life where resin degradation due to oxidative effects are anticipated
- Low Color Thow
- Superior Physical Stability: 93% plus sphericity and high crush strengths together with carefully controlled particle distribution provides long life and low pressure drop
- Complies With US FDA Regulations: Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA
Applications:
- Softening: ResinTech CG8-C is an 10% crosslinked cation resin optimized for industrial softening applications.
- Demineralization: ResinTech Cg10-H can be used as the cation component in a variety of demineralization configurations where a hydrogen form cation resin is coupled with a hydroxide form anion resin. The high density of CG10-H provides ideal separation in polishing mixed beds. CG10-H has higher total capacity and lower chemical efficiency compared to CG8-H.
- High Temperature Use: ResinTech CG10 is suitable for operation at temperatures as high as 280°F. At temperatures above 212°F, dissolved oxygen in the feed water is a powerful oxidant and can chemically damage the resin. Oxygen levels in the feed should be reduced to less than 0.05 ppm to ensure a reasonable service life of the resin.
