Phosphate Antimicrobial Is New for Plastics.

An antimicrobial based on a neutralized amine phosphate is being used in a new line of polymer concentrates. Intersept Specialty Products, Kennesaw, Ga., recently received EPA registration approval of its Intersept antimicrobial for use in polymer concentrates. It has also formed an alliance with thermoplastics compounder PolyChem Alloy, which just moved to new headquarters in Lenoir, N.C. PolyChem will produce a line of concentrates for injection molding and extrusion made with Intersept and market them under the name PolySept.

Intersept antimicrobial has been registered with EPA since 1982 for use in carpet backing, ceiling tiles, and paints. It's said to be a relatively nontoxic compound that is less hazardous to handle and use than phenolic or arsenical antimicrobials. Intersept is said to be highly effective against fungi and bacteria. PolyChem has found a way to incorporate this amber, viscous liquid into 20%-active polymer concentrates for polyethylene, polypropylene, polystyrene, and ABS.
