ResinTech CG8-C Coarse Grade Cation Exchange Resin, Na Form, 1 Cubic Foot
ResinTech CG8-C is a sodium form 8% crosslinked gel strong acid cation resin. CG8-C is a course mesh resin with low surface area and high void volume. ResinTech CG8-C is intended for use in high flow rate applications where the lowest possible pressure loss and highest possible flow rate is needed. CG8-C is available in the sodium form.
Features & Benefits
- Highly Uniform Coarse Particle Size: 16 to 30 mesh size provides low pressure drop in high floret applications and helps prevent suspended solids from restricting flow.
- 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 8% crosslinked cation resin optimized for industrial softening applications. CG8-C is suitable for hot water applications and for waters that contain modest levels of chlorine
- High Flow Rate Use: CG8-C is made with large bead size which increases the void space between the beads and reduces the surface area, thus reducing the resistance to water flow through the resin bed. Because the resin bed has lower pressure loss the resin can operate at high flow rates. High flow rates are useful in polishing applications where a large resin volume is not need to provide a long throughput between regenerations. It should be understood that the rate of ion exchange is somewhat slower due to the large bead size.
