HDPE Milk bottles & Carbon Black
So i have been doing quite a bit of experimenting on different plastic types compression molding; and so far HDPE has been a tough one;
I have been sourcing my HDPE through 2 types of products; bottles containing agressive liquids (acetone for example) and milk bottles.
I had my first tests where all HDPE was put to melt together. MAJOR ERROR !!
W realized that some additives must had been added in the HDPE to resist to the liquid it would contain; the result when we tried to melt it : the additives burned before we manages to get to the melting phase…
But with milk bottles another problem arrived;
HDPE Milk Bottles are made of 3 layers being : HPDE / Black Carbon / HDPE
The middle layer is IMPOSSIBLE to detach from the 2 others; and malting gives a really weird output.
My concern is the following; Carbon Black not being plastic; the fusing output of milk bottles will not be 100% HDPE
Any thoughts on the subjects y’all ?
