Thermax Tulsion A-23 SM

Summary

Product identification

TULSION® A-23 SM is a tough gel strong base anion exchange resin (Type I) based on a polystyrene matrix with quaternary ammonium Type I functional groups.

Operating limits

• pH range: 0 to 9
• Maximum operating temperature: 175 °F (80 °C)
• Temperature stability: 175 °F (80 °C)

Feed water

TULSION® A-23 SM exhibits good operating capacity for weak acids such as silicic and carbonic, along with strong mineral acids, when used in water treatment with a strong acid cation exchange resin like TULSION® T-42 SM.
