Polyimide Prices, Demand and Supply Overview

Polyimide is a high-performance polymer produced by the polycondensation of dianhydrides with diamines, prized for exceptional heat resistance, mechanical strength, and dielectric properties. The largest demand pull comes from flexible printed circuit board film and semiconductor packaging applications, followed by aerospace composite and insulation film use, with demand accelerating on AI chip packaging, semiconductor, and electric vehicle growth.

Global polyimide prices tracked close to the USD 67.00 to USD 73.00 per KG range projected for 2026, firming on AI, semiconductor, and electric vehicle demand. US prices averaged USD 78.40 per KG in Q1 2026, up 2.5 percent from Q4 2025 and the highest among reporting regions, as strong semiconductor packaging and aerospace demand met disciplined specialty supply and producers held premium film grades tight. Japan lifted levels on announced film-grade increases and strong electronics demand, South Korea stayed firm on display and circuit demand, while China's lower-cost capacity kept it the most competitive source.

What is Polyimide Price in August 2026?

Polyimide prices held a firm tone through August 2026, tracking close to the Q1 2026 levels across all tracked regions, as strong semiconductor packaging, AI chip, and electric vehicle demand continued to support the market against disciplined specialty supply.

  • North America (US): US polyimide prices held near USD 77.20 to USD 79.60 per KG, close to the USD 78.40 per KG recorded in Q1 2026 and the highest among tracked markets, as strong semiconductor packaging and aerospace demand met disciplined specialty supply and higher import freight reduced offshore competition.
  • APAC (Japan): Japanese polyimide prices held near USD 72.90 to USD 74.90 per KG, close to the USD 73.90 per KG recorded in Q1 2026, as announced film-grade increases and strong electronics demand continued to lift levels across the region's producer base.
  • APAC (China): Chinese polyimide prices held near USD 54.00 to USD 55.60 per KG, close to the USD 54.80 per KG recorded in Q1 2026 and the most competitive among tracked markets, as lower-cost domestic capacity continued to keep China the most affordable sourcing region globally.

Polyimide Price Forecast for 2026

The balance of supply and demand for PI film through the rest of 2026 leans clearly to the upside. Producer cost floors are firm, held up by steady feedstock values and by elevated freight after the mid-year disruption around the Strait of Hormuz raised shipping and insurance costs on east-west routes. Demand is growing fast, led by artificial-intelligence server build-outs, semiconductor packaging, and rising electric-vehicle and foldable-display use. Japanese producers have signalled price increases on film grades from the second quarter, which should reinforce the climb. The main upside risk is a supply squeeze in a tight specialty market. The main downside risk is faster capacity additions in Asia that ease tightness and slow the rise.

Region 2026 Price Range (USD/KG) Outlook
Global Average 67.00 - 73.00 Firm rise on AI, semiconductor, and electric-vehicle demand
United States 77.00 - 83.00 Aerospace and semiconductor demand sustain the premium end
Japan 73.00 - 80.00 Announced film-grade increases and strong electronics demand lift levels
South Korea 64.00 - 70.00 Display and circuit demand with new capacity keep the market firm
China 54.00 - 59.00 Lower-cost capacity keeps the region the most competitive source

Three factors dominated: surging electronics and semiconductor packaging demand, growing electric-vehicle and display use, and tight specialty supply that limited availability.

The global average is expected in the USD 67.00 to 73.00/KG range for the rest of 2026, assuming firm electronics demand and announced film-grade increases hold while Asian capacity additions stay measured.

The United States and Japan carry a premium on semiconductor, aerospace, and high-grade electronics demand, South Korea sits firm on display and circuit use, and China prices lowest thanks to large low-cost capacity.

This report is updated monthly. For real-time pricing intelligence, contact the Expert Market Research team directly.

Prices respond mainly to feedstock costs, specialty capacity discipline, and downstream electronics and battery demand. Freight shifts and announced producer increases can amplify short-term moves across regions.

The United States, Japan, and South Korea host the established premium producers, while China is the fastest-growing volume source. Tight specialty supply means any disruption ripples across markets within one to two quarters.

Buyers can use quarterly trends and forecasts to time contracts, choose between fixed-price and index-linked supply, and secure volumes ahead of announced increases. Regional price gaps also help teams weigh alternative supply geographies when premium grades turn scarce.
