If you make or use glycols
HERE'S GOOD NEWS!
Sodium Borohydride Removes Trace Impurities Fast, At Low Cost! At today's record-breaking low prices, if you make or use glycols—especially for plasticizers—it makes good sense for you to get facts now! Complete information, samples and on-the-spot technical service are yours for the asking!
In less than an hour you can reduce 50% of the aldehyde in your glycols without adding any significant costs to your product or process. Sodium borohydride works fast at room temperature and is extremely effective using any of three simple treatment techniques. In pellet form, sodium borohydride is ideal for fixed-bed purification. In powder or liquid form (SWS) you can add small amounts directly to your process stream. Or, even easier, add borohydride to your glycols 'while packaging them in drums. The borohydride will "clean up" contaminents while glycols are in inventory or in transit. For re-cycling contaminated glycols, borohydrides are equally effective and easy to use.
