What are the common filler materials used in PP, PE, LDPE, HDPE, and PVC-moulded materials?
To give a background - I own a limestone quarry and selling calcium carbonate in powder form. I want to make value added products from CaCO3, which I came across the filler master batches. But I am not sure what type of plastics use that. Answer to this will help me identify a particular sector and do targeted market analysis as I understand different end users require different grades of CaCO3 fillers.
