Technora
In this article, we will explore the impact and relevance of Technora in contemporary society. Technora is a topic that has aroused the interest of experts, academics and professionals in various fields, due to its influence on different aspects of daily life. Over the next few lines, we will analyze the implications of Technora in the social, economic, cultural and political spheres, examining how this phenomenon has shaped our perceptions, behaviors and interpersonal relationships. Likewise, we will delve into the different perspectives and debates that have arisen around Technora, with the aim of shedding light on its multiple facets and realities.
Technora is an aramid that is useful for a variety of applications that require high strength or chemical resistance. It is a brand name of the company Teijin Aramid.
Technora was used on January 25, 2004 to suspend the NASA Mars rover Opportunity from its parachute during descent.
It was also later used by NASA as one of the materials, combined with nylon and Kevlar, making up the parachute that was used to perform a braking manoeuvre during atmospheric entry of the Perseverance rover that landed on Mars on February 18, 2021.
Production
Technora is produced by condensation polymerization of terephthaloyl chloride (TCl) with a mixture of p-phenylenediamine (PPD) and 3,4'-diaminodiphenylether (3,4'-ODA). The polymer is closely related to Teijin Aramids's Twaron or DuPont's Kevlar. Technora is derived from two different diamines, 3,4'-ODA and PPD, whereas Twaron is derived from PPD alone. Because only one amide solvent is used in this very straightforward procedure, spinning can be completed immediately after polymer synthesis.
