Polyetherimide (PEI) Price Forecasts & Market Foresight Q3 2026

Outlook: Strongly Bearish

Confidence: High

In India, PEI prices are expected to remain under corrective pressure during Q3 2026, driven by softer Bisphenol A (BPA) and m-Phenylenediamine (MPD) feedstock costs, adequate import availability, and monsoon-related weakness in industrial activity.

Cautious, need-based procurement from downstream engineering plastics consumers and sufficient inventories are expected to keep market sentiment subdued before prices gradually stabilize toward the end of the quarter.

Historically, several events have caused significant fluctuations in Polyetherimide (pei) prices

  • Surge in Demand for Lightweight Materials in Automotive and Aerospace (2021-2023): As industries began focusing more on lightweight and high-performance materials, demand for PEI surged in sectors such as aerospace, automotive, and electronics. The shift toward electric vehicles (EVS) also drove demand for high-temperature-resistant plastics like PEI. This increased demand contributed to upward pressure on prices, particularly in 2021-2023 as industries recovered post-pandemic. 
  • Global Semiconductor Shortage (2020-2022): The global semiconductor shortage, caused by high demand and disrupted production, indirectly impacted the PEI market. PEI is widely used in the electronics and automotive industries, both of which were severely affected by the chip shortage. Reduced production in these sectors softened the demand for PEI temporarily, preventing major price spikes during the period, though supply chain recovery helped stabilize prices by late 2022. 
  • COVID-19 (2020-2021): The COVID-19 pandemic had a significant impact on the PEI market, causing widespread supply chain disruptions, particularly in early 2020. Lockdowns and restrictions on industrial activities led to decreased production and transportation delays. PEI prices saw volatility, with some regions experiencing shortages and subsequent price spikes. As industries began to recover by late 2021, prices stabilized but remained elevated due to pent-up demand and limited supply.
