Envalior GmbH

But what about the non-structural interior applications, like the aesthetic cabin parts where you don't necessarily need the extreme structural rigidity of PPS or PEI? but you still have to legally pass those aviation fire regulations.

For those applications, Envalior offers TPEX with a matrix of flame retardant polycarbonate.

The chemical mechanism of the flame retardant allows it to meet all the FST requirements.

And polycarbonate is a much more economical choice.
