A couple of the usual wire insulations on the market are based on the PTFE and ETFE polymers. Jaguar Industries has actually been a leading supplier of PTFE Wire, PTFE Cable & PTFE Tubing for 30 years.
The tensile durability of ETFE can be as much as 34 % higher compared to PTFE. PTFE has a coefficient of rubbing one-third of ETFE making it a much more ideal cable insulator for locations where cord packages could chafe against one another.
There are likewise significant differences in the thermal residential properties of each material. The melting temperature of PTFE is 327oC and ETFE 267oC, but both of these materials start to soften shown below at lesser temperature levels. The operating temperature level of the materials is less. Further, PTFE has a Limiting Oxygen Index (the minimum percent focus of oxygen at which the polymer will certainly burn) greater than 95 % whereas ETFE is somewhere in between 30-36 %, indicating that PTFE should be thought about in greater air atmospheres.
A location of interested in both of these products is the outgassing of fluorine over prolonged periods (outgassing is when the constituent parts of an insulation, when it come to PTFE and ETFE– fluorine, getaway from the insulation). The free of cost fluorine atoms from these materials can make destructive hydrofluoric acid which is of biggest issue in enclosed locations.
Lastly, it ought to be kept in mind that there is also cross-linked ETFE wire on the market.
