While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

23 Jul 2024
Prices of PE, PP, PVC, PET Largely Firm, Flat for PS
By most measures, pricing for the five commodity resins appeared to be holding firm going into the third quarter.

21 Jun 2024
Prices Up for PE, ABS, PC, Nylons 6 and 66; Down for PP, PET and Flat for PS and PVC
Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.

31 May 2024
