From PP prices down, other commodities up in a turbulent March (Plastics News):
Polypropylene was the odd resin out in March, with North American prices falling, while prices for other commodity resins in the region saw increases. […]
PP prices fell an average of 12.5 cents per pound in March. Demand for the material remained strong across many end markets. The price decline was the result of a demand drop for propylene monomer feedstock.
Prices for all grades of PE moved up 7 cents per pound in March, after increasing by that same amount in February. Prices had increased by 5 cents in both January and December, as the market was tight even before the storm hit. North American PE prices are up a net of 39 cents since January 2020.
