What are Key Advantages of Polytetrafluoroethylene and how are they leading to its High Demand?

The electrical & electronics sector has been witnessing significant growth over the past few years. As per the Semiconductor Industry Association, the worldwide demand for semiconductors reached a shipment of more than 1 trillion units. In addition to this, the sales of semiconductors in China rose by more than 20.5% in 2018 as compared to 2017. The disposable income of people around the world is increasing, owing to which, they are able to afford different electronics items. This expansion of the industry is bound to create requirement for materials that are utilized in the production of different products. 

It is due to these factors that the demand for polytetrafluoroethylene (PTFE) is growing. It is utilized in the electrical & electronics industry for various applications, such as cable tires, battery binders, brush holders, circuit breakers, connectors, barb insulators, and in the fabrication of semiconductor devices. PTFE is a hydrophobic material that is primarily known for its non-stick attributes. It has high density and is resistant to high temperatures, ascribed to which is utilized a number of applications. As per a report by P&S Intelligence, the global PTFE market is predicted to attain $2,953.6 million by 2024, rising from $2,197.8 million in 2018, advancing at a 5.0% CAGR during the forecast period (2019–2024).

PTFE has different types, namely aqueous dispersion, powder, and granules, among which, the demand for granular types was the highest in the past. Even though powder and granular forms have similar properties, granular is preferred more, as it is relatively difficult to mix fine-powder PTFE with solids for forming a uniform blend. In addition to this, the powder variant is more expensive than the granular one. The granular type is ideal to compress molding for the production of sheets, tubes, and rods. 

PTFE has a number of applications, including tapes, tubes, fuel additives, films & sheets, wires & cables, fabrics, and coatings. Out of all these, the largest demand for PTFE was created for the coatings application in the past, which is owing to the high requirement for PTFE-coated seals, valves, and rings in the industrial processing sector. The major end users of PTFE are medical, automotive, industrial processing, construction, and electrical & electronics sectors. The largest demand for the chemical in the past was created by the industrial processing sector, as PTFE-coated piping, gaskets, and linings are widely utilized in the sector. 

The ability of the material to enhance the heat and chemical resistance, improve the electrical load bearing capacity of the base material, and reduce sticking and friction are some of the major reasons for its increasing adoption in the industrial processing sector. Geographically, Asia-Pacific has been the largest PTFE market in the past and is further predicted to make the most use of this material in the coming years as well. This is particularly due to the high demand for PTFE from the electrical & electronics and automotive industries in the region. 

In conclusion, the demand for PTFE is growing because of the expansion of the electrical & electronics industry.
