G-Etronax EP FR - Tube

EP FR (EP GC 23) is a material with a high glass content that is wear-resistant and has good thermoelectric properties. It is an epoxy-based material characterized by its self-extinguishing properties.

EP FR (EP GC 23) vs EP 10

G-Etronax EP FR is the flame-retardant counterpart to EP 10 (equivalent to the G10 grade): the two share the same temperature class, and the difference between them is essentially flame retardancy. EP FR is UL 94 V-0 approved and self-extinguishing, while EP 10 is not.
Also available as sheet (FR4).
