PTFE, e tsebahalang ka hore ke Teflon, e ne e se tšibollo e lokiselitsoeng. Ho 1938, DuPont e ile ea khoptjoa ke ntho ena e makatsang ho e-na le ho tsieleha, ho tsosa phetoho ho mahlale a thepa le lits'ebetso tsa khoebo.
Hoseng ho hong ho 1938, Roy Plunkett, lebenkele le lecha la lithethefatsi, o ne a bapala ka mafolofolo le liteko tsa hae hukung ea DuPont. Mosebetsi oa hae o ne o bonahala e le oa motheo: fumana sesebelisoa se secha sa ho pholisa.

Leha ho le joalo, feela ha Roy a lumela hore e ne e le mosebetsi o tloaelehileng feela, lintlha li ile tsa fetoha. O ile a boloka khase ea tetrafluoroethylene ka cylinder 'me a ipolela hore ke eena: “Ho lokile, ke tla u bona hosane.” Letsatsi le hlahlamang, ha a khutla ho ea ntšetsa pele teko ea hae, o ile a fumana hore khase e ne e nyametse ka tsela e makatsang, ho siea qubu feela ya phofo e tshweu. Hantle, sena se ne se hlile se fapane le script eo ae lokiselitseng. Nahana ka maikutlo a hae ka nako eo: halofo ya ho fekeha, halofo ea bohelehele. Ha ho ntse ho hlahlojoa, he uncovered that this unusual white powder had some trendy superpowers: it was hostile to almost all chemicals, can remain amazing at extreme temperatures, and was as unsafe as oil. Instantly, Luo recognized that while he had yet to locate a brand-new refrigerant, he had actually accidentally discovered the secret component of the cooking area superhero of the future – non-stick frying pans. From then on, frying eggs was no longer a challenge, and cleaning pots came to be a breeze.
Although the discovery of PTFE was unintentional, it had huge innovative importance for the plastics industry and many other areas, such as aerospace, automobiles, lisebelisoa tsa elektronike, and appliances. PTFE is extensively made use of because of its one-of-a-kind chemical and physical properties – extremely low friction coefficient, ho hanyetsa mocheso o phahameng, tshireletso ya dikhemikhale, and non-stickiness. From kitchen utensils to integral parts of the space shuttle, PTFE made many ingenious applications feasible. However while PTFE (Teflon ®) marked an innovative development in materials science, it was only the start of a lengthy and tough road to commercialization and extensive application. The initial obstacle was not just to find a new product but additionally to find out how to attain massive manufacturing and how to apply it in various fields.
The processes of monomer synthesis and regulated polymerization of PTFE were not completely developed, making it tough to create PTFE in big quantities or a viable fashion. While the material’s special buildings were useful in the end application, they likewise postured considerable obstacles during the production process. Unlike other common plastics, PTFE is not soluble in solvents, acids, or bases and does not merge a flowable fluid. Ho e-na le hoo, when heated, it becomes a hard, clear gel that does not melt and moves like plastics.
(Roy’s Notes: Discovery of PTFE)
To overcome these challenges, researchers and designers had a hard time to find procedures from various other areas, such as adapting strategies from steel and ceramic handling. To shape PTFE, a process called paste extrusion was used, which was borrowed from ceramic handling. Although conventional molding and developing techniques had some difficulty refining PTFE, it was possible to produce PTFE components. Ka 1947, comprehensive research study and experimentation had thrived, and a small-scale production facility was developed in Arlington, New Jersey.
