Great Lakes Adds Clearlite Nucleating and Clarifying Agents to Its Polymer Additives Portfolio

INDIANAPOLIS, INDIANA-Great Lakes Chemical Corporation (NYSE:GLK) today announced the introduction of Clearlite NU 004 nucleating agent and Clearlite NU 005 nucleating and clarifying agent to its extensive portfolio of polymer additives.

Clearlite NU 004 is a micronized, sodiumbenzoate-based product that increases the overall crystallization rate of semi-crystalline polymers like polypropylene, polyamide and polyester, resulting in productivity gains and improved mechanical and physical properties. Clearlite NU 005 is a sorbitol-based product that in addition to its nucleating function also acts as a clarifying agent, which reduces haze and significantly increases polymer transparency.

"Nucleating agents are used extensively by Great Lakes' core customers, and we have long been incorporating these products in our Anox® NDB® customized additive blends," commented Henri Steinmetz, executive vice president of polymer stabilizers for Great Lakes. "The addition of nucleating and clarifying agents to the company's own broad portfolio is a logical step that further enhances our service to the polymer industry."

Clearlite NU 004 and Clearlite NU 005 are the first in a new line of nucleating agents to be offered by Great Lakes. Further additions that complement these products will follow in the near future.
