Hi,
I am searching for production of polypropylene thread using a needle felting method. I would like to know what components and how much are needed to produce polypropylene (how much) and what are the emissions related to that. However, I couldn't find any information.
Also if you can guide me the same information on polystyrene?
I really do appreciate your time and guidance.
