Isn't natural gas the feedstock for crackers that go into the ethylene and propylene responsible for making of plastics?

With the over abundance of NG and the short on Ethylene plants in the US with only DOW Chemical talking about building a large facility (Gulf Coast) to provide feedstocks, plastic production in the US looks stable to declining and is a commodity at best. Unless you get on the specialty end like, EPR, high voltage insulation or semi conductor resins. The middle supply chain may be better to look at with the other C2Hx components (butene, hexene, hexane, etc) in the long run.

Natural Gas liquids, not the natural gas (methane). Ethylene and propylene are made from ethane.
