7300 FOAMING PLASTIC MASTERBATCH

 
7300 FOAMING PLASTIC MASTERBATCH
A Most Widely used Nitrogen foaming Masterbatch For Foamed Plastics

Introduction-

Foaming plastic masterbatch 7300 is particularly adapted for use in unicellular procducts where low gas loss be diffusion is required since it blows by releasing nitrogen.It is non-odorous in itself and imparts no odor to the finished products for which it is used and may be used in white or light colored compounds without the objectionable discoloration and staining obtained with many organic chemicals although it is a yellow pellet, the decomposition residue by heat is white. 7300 is broadly used blowing agent for most polymers processing, and should not be used with beryllium or copper tooling in injection molding structural foam.
