General description

Poly(tetrafluoroethylene) is a fluoropolymer that is commercially known as PTFE. Its properties include high thermal stability, excellent chemical resistance, low dielectric constant and low surface energy. It is a hydrophobic polymer that is majorly used as a protective coating on the metal surface.[1][2]

Application

Inert lubricant.

Suitability

Low coefficient of friction, low critical surface energy and excellent antistick properties.

Storage Class Code

11 - Combustible Solids

    Multicapillary column ion-mobility spectrometry (MCC-IMS) may identify volatile components in exhaled gas. The authors therefore used MCC-IMS to evaluate exhaled gas in a rat model of sepsis, inflammation, and hemorrhagic shock. Male Sprague-Dawley rats were anesthetized and ventilated via tracheostomy
