Foaming Agent for PC Gives Off No Moisture

A new exothermic chemical foaming agent is formulated specifically for polycarbonate structural foam, injection molding, and extrusion.

A new exothermic chemical foaming agent is formulated specifically for polycarbonate structural foam, injection molding, and extrusion. XO-230 from Bergen International, Rochelle Park, N.J., reportedly produces no moisture byproduct, unlike some CFAs, thereby eliminating brittleness from polymer degradation. Offered in pelletized masterbatches, XO-230 can be used for maximum density reduction in structural foam or for sink and warp reduction in injection molding.
