FEP (Fluorinated Ethylene Propylene) is a high grade material with a long list of truly some remarkable properties. Here are some highlights:outstanding chemical resistance;high thermal stability (service temperature rating up to more than 200 °C);extremely low flammability.
And this is only an abstract. Please check the Additional information below for more details.
As with most things in life, it comes at a price: the high melting temperature of 260 °C means that you will need a all-metal hotend to handle this. And because it is just release from our factory, we do not have in-depth guidelines on how to get the best results. But if you need the above material specifications, there is no real alternative.
