If you need specific information, which is not currently within the scope of the report, we will provide it to you as a part of customization The changes in chemical properties can highly depend on the type of additive used, but. in general, it also leaves positive results. The resulting polymer is terminated with sulfate ester groups, which can be hydrolyzed to give OH end-groups. [17] This report forecasts revenue and volume growth at global, regional, and country levels and provides an analysis of the latest industry trends in each of the sub-segments from 2014 to 2025. For this study, Grand View Research has segmented the global Polytetrafluoroethylene (PTFE) market report based on product, application, and region: PTFE tubes are used in gas-gas heat exchangers in gas cleaning of waste incinerators.

Algoflon® DF offers the low friction, electrical and high temperature characteristics needed for wire insulation. The requirements for this application also include: On the other hand, North America and Europe is one of the mature industries for electronics, led to continuous technological advancements for end products. This factor is projected to increase the demand for PTFE in North America and Europe over the forecast period. Polytetrafluoroethylene (PTFE) Market Share Insights Processing PTFE can be difficult and expensive, because the high melting temperature, 327°C (621°F), is above the initial decomposition temperature, 200°C (392°F). [33] Even when molten, PTFE does not flow due to its exceedingly high melt-viscosity. [34] [35] The viscosity and melting point can be decreased by inclusion of small amount of comonomers such as perfluoro (propylvinyl ether) and hexafluoropropylene (HFP). These cause the otherwise perfectly linear PTFE chain to become branched, reducing its crystallinity. [36] Fluoropolymer PTFE coating services from Surface Technology UK". Surface Technology . Retrieved 26 February 2018. The major application of PTFE, consuming about 50% of production, [ citation needed] is for the insulation of wiring in aerospace and computer applications (e.g. hookup wire, coaxial cables). This application exploits the fact that PTFE has excellent dielectric properties, specifically low group velocity dispersion, [39] especially at high radio frequencies, [39] making it suitable for use as an excellent insulator in connector assemblies and cables, and in printed circuit boards used at microwave frequencies. Combined with its high melting temperature, this makes it the material of choice as a high-performance substitute for the weaker, higher dispersion and lower-melting-point polyethylene commonly used in low-cost applications.

However, global product demand is projected to exceed the supply, particularly due to novel applications, thereby propelling the market growth. The global industry is concentrated in nature with prominent industry participants accounting for a majority of its share. Companies are trying to reduce production costs, improve supply chain dynamics, and develop high-quality products by investing in R&D. High operational and maintenance costs associated with PTFE resin plants are keeping the threat of new entrants to a minimum. Product Insights Polytetrafluoroethylene (PTFE) was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont. As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty". Since Plunkett was measuring the amount of gas used by weighing the bottle, he became curious as to the source of the weight, and finally resorted to sawing the bottle apart. He found the bottle's interior coated with a waxy white material that was oddly slippery. Analysis showed that it was polymerized perfluoroethylene, with the iron from the inside of the container having acted as a catalyst at high pressure. [4] Kinetic Chemicals patented the new fluorinated plastic (analogous to the already known polyethylene) in 1941, [5] and registered the Teflon trademark in 1945. [6] [7] The Asia Pacific accounted for the largest market share in 2017 and is projected to continue the trend over the forecast period. It is also one of the fastest-growing regions. This growth is primarily credited to rapid expansion in the industrial and chemical processing industry in major economies, such as China and India. Also, the rapid expansion of the automotive industry in the region is projected to fuel the product demand further. In the 1990s, it was found that PTFE could be radiation cross-linked above its melting point in an oxygen-free environment. [13] Electron beam processing is one example of radiation processing. Cross-linked PTFE has improved high-temperature mechanical properties and radiation stability. That was significant because, for many years, irradiation at ambient conditions has been used to break down PTFE for recycling. [14] This radiation-induced chain scission allows it to be more easily reground and reused. Li, G. et al. Rheological properties and foam preparation of biodegradable poly(butylene succinate). J.

Rheological measurement was carried out on the rotating rheometer (TA ARES G2, American) at 130 °C. 1.0% strain was set and the frequency varied from 100 to 0.01 Hz. At the same temperature and strain parameters, a time sweep of 1000 s duration was performed. The creep properties of the materials were tested at 130 °C with a constant stress of 100 Pa and duration of 1000 s. Microstructure analysis The granular PTFE materials are produced by suspension polymerization in an aqueous medium with a meager or no dispersing agent. The granule PTFE material is mainly used in compression, isostatic, and ram extrusion methods. a b Sun, J.Z.; etal. (1994). "Modification of polytetrafluoroethylene by radiation—1.
