Cellborn
Endothermic type blowing agent

Cellborn

Eiwa’s endothermic type blowing agent and compounds developed for Extrusion molding for PS, ABS Pe and PP.
Nontoxic, Odor free, and white color blowing agent manufactured by carbon dioxide gas process.
It is made out of Sodium Bicarbonate so easy is to handle offering safety operation as well as optimum storage conveniences. It gives flexibilities to various molding options.
Its fine cell contributes to the surface smoothness. Its bubble core formation for PS and PP will help to reduce the aging time. It is POPL registered product so favorite for food packaging application.
