Specifically HPDE or PET production processes

What monomers and catalysts are used?

This thread will be liberally sprinkled with references to baws, truck nuts, and New Iberia haircuts.

The only thing that will happen in this thread is a bunch of guys making 50k/year will say baw and truck nuts a lot. Probably gonna be a few more cooking jokes too

I think you meant HDPE, which should lead you to "polyethylene", which would lead to the monomer ethylene. Everything you seek can be found on the Internet. Why are you asking here?

Polyethylene. Feedstock is Ethylene, injected into a reactor, injected with a catalyst which turns the gas into a washing detergent type powder. It is then put into an extrusion process where additives are added, then melted and cut by Set of knives on an electric motor into pellets.

ETA: Nobody is going to tell you what catalysts/monomers they use.....

The 50k was referencing the jealous dudes that always say baw and truck nuts in every operator thread, not the operator baws
