Perfluoropoly ether oils

In contrast, Karvaly et al. (2008) showed that a commercially available barrier cream and a perfluoropoly-ether oil applied prior to exposure reduced p.c. uptake of sulfur mustard. In particular, perfluoropolyether oil was highly effective, preventing sulfur mustard exposure for a period of 20 min. A petroleum jelly ointment, however, had no protective effect, even when applied prior to exposure. 

Synthetic pump oils are also called inert oils. So far, there are mainly two types of synthetic pump oils available perfluoropoly ethers (PFPE) and... 

Perfluoropolyethers emerged on the market in the early 1970s. The first perfluoropoly ether was the homopolymer of hexafluoropropylene oxide produced by DuPont, which has the structure [—CF2CF(CF3)0—] and this new lubricant material was called Krytox."- Krytox was and is used in most of the vacuum pumps and diffusion oil pumps for the microelectronics industry because it does not produce any hydrocarbon or fluorocarbon vapor contamination. It also has important applications in the lubrication of computer tapes and in other data processing as well as military and space applications.
