Flame retardant materials for CNC machining

0
Z
4

Hello,

I’m working on a project that requires producing flame retardant plastic connectors with very precise tolerances. I’m looking into CNC machining as injection molding seems not to be an option due to the precision required.

Maybe anyone could advise what flame retardant plastics should I consider for cnc that have UL recognition or certification? Ensuring the material meets safety standards is crucial for my application. Thank you, would appreciate any recommendations

Hi Zdenek,
To complete Niko’s answer, you can check this detailed article about flame retardant materials https://xometry.pro/en-eu/articles/flame-retardant-plastics-ul-94/ You’ll find a list of materials which are, for most of them, UL 94 V-0 rated.
I also would like to bring your attention to the fact that depending on your application, V-0 rating might not be necessary and you could consider V-2 or V-1 (or maybe even HB) rated materials. The grade of flame retardancy should be chosen based on the part, its application, and the environment in which it will be used.

      Hi and thanks for your question. In CNC we have an ABS and Peek material rated UL94V0. Please add this demands in the comment, if you order at Xometry, there different grades are available.
