C-15 H (LS) Features

Very Low Sodium and Metal Content

Special manufacturing conditions ensure very low metal content.

Elemental analysis, dry basis

Sodium (Na)<3 ppm
Cobalt (Co)<10 ppm
Copper (Cu)<10 ppm
Aluminum (Al)<50 ppm
Iron (Fe)<25 ppm

No Organic Chlorides Leakage

No chlorinated solvents are used in the manufacturing of Aldex C-15 H (LS) resulting in no leakage of organic chlorides.

Very Low TOC

Non solvent sulfonation and special manufacturing processes assure very low TOC leakage.

Uniform Particle Size

98% of all beads are in the minus 16 to plus 40 mesh range giving a lower pressure drop while maintaining the superior kinetics of standard mesh size products.

Superior Physical Stability

90% plus sphericity and high crush strengths together with a very uniform particle size provide greater resistance to bead breakage while maintaining low pressure drop.

Safety Information

A material safety data sheet is available for Aldex C-15 H (LS). Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-15 H (LS) is not a hazardous product and is not WHMIS controlled.

Caution: Acidic and basic regenerant solutions are corrosive and should be handled in a manner that will prevent eye and skin contact. Before using strong oxidizing agents in contact with ion exchange resin, consult sources knowledgeable in the handling of these materials.
