The Polyolefin Plastomer Price Trend showed that cost-related factors became more important than demand during Q1 2026. Manufacturers faced higher expenses due to increasing ethylene prices, while natural gas costs also remained elevated. These rising production costs made it difficult for suppliers to maintain previous pricing levels. At the same time, delays in transporting raw materials and concerns about feedstock availability reduced supply flexibility. Even though buyers remained cautious, higher manufacturing costs continued to push prices upward.
