PITTSBURGH, Dec. 10, 2001 -- Sybron Chemicals Inc. has published a new product guide highlighting its complete line of Lewatit¨ ion exchange resins for industrial applications, including MonoPlus uniform-particle-size ion exchange resins.

The monodispersed resins, available in both gel and macroporous varieties, have been tested and proven in a host of worldwide applications. Typical uses include condensate polishing, cocurrent softening and demineralization.

MonoPlus resins' uniform-particle size promotes maximum kinetic and hydraulic resin performance, leading to higher throughput per cycle, lower water and chemical consumption and higher mechanical and chemical stability. Other benefits include longer life cycles, better backwashing properties and easier separation in mixed beds.

Sybron Chemicals is a wholly owned subsidiary of Bayer Corporation. The Bayer Group's state-of-the-art plant in Bitterfeld, Germany makes it the world's largest producer of monodispersed ion exchange resins.
