What It Is
IonPlus™ CA-10 is the standard 8% grade of Carbochem’s strong acid cation resin, supplied in the sodium form for water treatment. It is the resin that does the softening inside a water softener tank: hardness (calcium and magnesium) is exchanged for sodium as water passes through it, and a salt brine regeneration restores it.
Carbochem publishes only the summary figures above for CA-10. Send us your water test and flow rate and we will size the bed and salt setting for you.
Handling & Safety
Carbochem’s Safety Data Sheet for its IonPlus™ CA-10, CA-12 and CA-16 resins (revision May 2016) states that the ion exchange resin is not determined to be hazardous. It may cause irritation on direct contact with the eyes, and inhaling dust may irritate the airways, so wear safety goggles and rubber gloves when loading a tank. Keep it away from oxidizing agents, with which Carbochem says it is highly reactive. It is not regulated as hazardous goods for transport, and Carbochem notes that new or used ion exchange resins generally are not hazardous waste.
California Proposition 65: Carbochem’s SDS makes no statement about Proposition 65 either way — it neither gives a warning nor says the product is free of listed chemicals. Its composition section lists sodium polystyrene sulfonate (40–65%) and water (35–60%). If you need a written Proposition 65 statement for your records, ask us and we will request one from the manufacturer.
Warranty
Carbochem publishes no warranty terms for this resin. Its Safety Data Sheet says that “since the conditions of handling and use are beyond our control, we make no guarantee for results obtained, and assume no responsibility for damages incurred by use of this product.”
This is normal for ion exchange resins and is not a mark against the product: resin performance depends on the water it is fed and how the softener is run, which the manufacturer does not control.
For anything covered by our own sale terms — short shipment, transit damage, or the wrong item supplied — contact us on 408-969-2688 or sales@foreverpureplace.com. Those are our terms, separate from the manufacturer’s position above.

Frequently Asked Questions
Does it need electricity?
No. This is a bag of resin beads that goes inside a softener tank. The softener’s control valve may need power; the resin does not.
