PI Film - Global Industry Market Analysis Report 2020-2031

PI film, or polyimide film, is a high-performance polymer film known for its excellent high temperature resistance (long-term use temperature can reach 400°C, short-term resistance to more than 500°C), mechanical strength (tensile strength is usually 200-300 MPa), electrical insulation (breakdown voltage>150 kV/mm) and chemical stability. It is widely used in electronics, aerospace, automobiles, industrial manufacturing and new energy. Its molecular structure is based on aromatic diamines (such as p-phenylenediamine PDA) and dianhydrides (such as tetracarboxylic dianhydride PMDA) prepared by polyamic acid (PAA) prepolymer, and then dehydrated by high-temperature curing (300-400°C) to form a stable imide ring structure. The production of PI film requires high-purity monomers (purity ≥99.9%) and precision coating processes (such as cast or biaxial stretching). The film thickness is usually between 10-125 microns, and can be customized according to the application in transparent (golden), black (adding carbon black) or composite (laminated with metal foil). For example, in the field of flexible electronics, PI film is used as a substrate for flexible printed circuit boards (FPCs), supporting the thin and light design of wearable devices and folding screen mobile phones (such as the Samsung Galaxy Z Fold series); in the field of aerospace, it is used as an insulating material for high-temperature cables and satellite components, withstanding radiation and vacuum in extreme environments; in the field of new energy, it is used for lithium battery separator coatings or backplanes of photovoltaic modules to enhance durability and weather resistance. The production process requires strict control of environmental humidity (<50%RH) and particle contamination (cleanliness ISO 5 level), and online detection (such as infrared thickness measurement and defect scanning) is used to ensure the uniformity of the film surface and the absence of pinhole defects.

PI film has performed well in high-tech fields, but its advantages and disadvantages have triggered in-depth technical and market discussions. Supporters believe that its excellent comprehensive performance makes it irreplaceable under extreme conditions. For example, in 5G devices, PI film is used as a high-frequency, low-loss substrate (dielectric constant of about 3.5, loss factor<0.003), supporting millimeter-wave antennas and high-speed signal transmission; in aircraft engines, its high temperature resistance and corrosion resistance protect wires and sensors and extend service life; in electric vehicle batteries, it can withstand high temperatures and high voltages (>500 V) as an insulating layer, improving safety and cycle life. In addition, the lightweight properties (density of about 1.4 g/cm³) and flexibility of PI film make it suitable for flexible electronics and wearable devices, meeting the needs of consumer electronics for miniaturization and portability. However, critics point out that the production cost of PI film is high, and the high-purity monomers and complex high-temperature curing process (requiring special ovens and inert gas protection) have pushed up manufacturing costs (prices can reach $50-100 per square meter), which may limit its popularity in the low-end market. In addition, waste gas (such as DMAc solvent volatilization) and wastewater (containing acidic byproducts) in the production process may pollute the environment if not properly handled, and an efficient waste gas absorption and neutralization system is required. Some users also reported that PI film is difficult to process. For example, cutting or drilling may produce microcracks, which will affect the mechanical properties. Laser cutting or precision die-cutting technology is required. In addition, its hygroscopicity (about 1%-3%) in high humidity environment may cause dimensional changes, which needs to be improved by surface modification (such as hydrophobic coating).

In terms of market, the demand for PI film is closely related to the rapid growth of the global electronics industry, aerospace development, new energy popularization and intelligent manufacturing. Asia, especially China, has become the main market for PI film due to its leading position in the production of consumer electronics (smartphone production is expected to exceed 1.5 billion units in 2025), 5G equipment (the number of base stations exceeds 2 million) and new energy vehicles (production exceeds 10 million vehicles). The demand of Chinese companies (such as Huawei, BYD and CATL) in flexible screens, electric vehicle batteries and 5G antennas has promoted the widespread application of PI film, and domestic manufacturers (such as Times New Materials and Kangdexin) are also accelerating the localization of technology. The North American and European markets focus more on high-end applications and reliability. For example, the United States uses PI films as insulation and heat insulation materials in the aerospace field (such as NASA satellites and SpaceX rockets), which must comply with MIL standards; Germany and Japan use PI films in industrial robots and medical equipment (such as MRI insulation layers), emphasizing its durability and stability. The growth of market demand is also driven by the trend of intelligence and lightweight. The popularization of flexible electronics, wearable devices and new energy technologies continues to increase the demand for high-performance film materials. However, the market development also faces several challenges, including the supply of raw materials (such as PMDA and ODA) may be limited due to the high concentration of the global chemical industry (the main suppliers are Japan and the United States), and price fluctuations may push up costs; the high energy consumption in the production process (about 2000-3000 kWh per ton of film in the curing stage) and environmental pressure may be restricted by regulations (such as the EU's RoHS directive); in addition, the low cost of competitive materials (such as PET film or PEN film) may divert part of the low-end market.

In the future, the development of PI film may focus more on cost optimization, performance improvement and green manufacturing. The development of new monomers or improved polymerization processes (such as low-temperature curing or solvent-free processes) may reduce energy consumption and costs, making it more competitive in the market. The development of enhanced PI membranes, such as improving thermal conductivity (up to 1-2 W/m·K) or dielectric properties by adding nanofillers (such as graphene oxide or boron nitride), may broaden its application in high-power electronics and thermal management. In the field of new energy, the potential of PI membranes is worthy of attention, such as as high-temperature diaphragms in solid-state batteries or as proton exchange membrane substrates in hydrogen fuel cells to enhance durability and efficiency; in addition, its application in flexible photovoltaics and wearable medical devices will also become a growth point. However, the industry still needs to face some challenges, including how to deal with the stability of the raw material supply chain (such as dependence on monomer imports), environmental protection requirements for waste management during the production process (solvent recovery rate must reach more than 95%), and the difficulty of finding a balance between high performance and economy. Overall, PI film will continue to maintain its position due to its excellent performance and versatility in the high-tech field, but its future development will need to rely on technological innovation (new processes and composite materials), supply chain optimization (localization and diversification) and environmental protection upgrades to cope with increasingly fierce global competition and changes in market demand.
