How is Expanding Electronics Industry Driving Polyimide Films Market?

With the emergence of electronic devices, life has become exceptionally simpler for human beings. People are becoming increasingly dependent on these products for carrying out their day to day tasks, due to which the demand for electronics is surging. Furthermore, technological advancements in several industries, such as medical, automotive, and electronics, are resulting in the development of newer products every day. Because of these factors, the requirement for improvisation in designs of devices and coating materials is growing, which, in turn, is driving the demand for polyimide films in the electronics sector. These films are utilized in the developmental process of flexible printed-circuit (FCP) boards, recording devices, rotating machines, integrated circuits, and electric wires. Moreover, polyimide tapes are also used in capacitor & transformer insulation, gold leaf masking during wave soldering, coil insulation, and magnetic wire insulation. 

As per a study conducted by P&S Intelligence, the global polyimide films market generated a revenue of $1,850.0 million in 2016 and is predicted to advance at a 10.1% CAGR in the near future. The various application areas of polyimide films are specialty fabricated products, motor/generators, FCPs, pressure sensitive tapes, and wires & cables.

Among all these, the largest demand for polyimide films was created for the FCP application during 2013–2016. Polyimide films are utilized as an insulating material for the manufacturing of FCP; in a single layer FCP, these films are used as base layer on the single metal layer and in the case of multi-layer FCP, polyimide films are used for developing inner layers. A buffer is created against mechanical stress and heat transfer by making use of these films. Because of these factors, the FCP application is projected to continue creating highest demand for polyimide films in the coming years. 

The polyimide films market is witnessing significant growth due to the different applications of polyimide films in various industries. This is due to the exceptional properties of these films such as thermal stability, ability to withstand a wide range of temperatures, flexibility, durability, chemical resistance, excellent tensile strength, low weight, water absorption characteristics, and damp-proof usage. Other factors leading to the rising demand for polyimide films over other coating materials include its abrasion and cut-through resistance characteristics, cost-effectiveness, faster design times, and ability to fabricate nanoscale features. Ascribed to all these properties, polyimide films find applications in a variety of industries such as medical, military, medical, and as mentioned above electronics.    

As the technological advancements are taking place in every field, the device materials and coatings are also witnessing innovations. This has resulted in the emergence of polyimide tubing, which is a lightweight thermoset plastic with properties such as chemical interaction, flexibility, and resistance to heat. Due to these properties, polyimide tubing is gaining traction in the medical design market as the need for minimally invasive surgical devices is growing. In addition to this, polyimide tubing also has the potential to be utilized as an electrical and thermal insulator for fluid and gas delivery. Owing to all these factors, the demand for polymer films is predicted to rise in the coming years.
