Please,
I already asked for additives to blend with PP to realize a foaming operation using microwaves. I forget your answers.
I know it need to create electronic conductivity in the polymer matrix.
One solution could be: ''PP + blowing agent'' + Carbon black, result is not so good.
Some others additives to replace carbon black or in addition with carbon black ????? (metallic powder?)
Thanks in advance.
