Flame retardancy can be tested with several standards, the most common standards are the UL 94 standard which is widely used for e.g. electrical components and the FAR norms which were developed for aerospace applications.
We offer 4 materials with flame-retardant properties on OnSite:
| Technology | Material | Standard used for testing (click to download certificate*) | Test result (rating) | valid from wall thicknesses above |
| Selective Laser Sintering | PA 2210-FR |
UL 94 |
V0 | 3.0 mm |
| PA 2241-FR |
FAR 25.853 |
Passed | / | |
| Fused Deposition Modeling | PC | UL 94 | HB | 3.0 mm |
| Ultem 9085 |
UL 94 |
V0 | 1.5 mm |
PA 2210 FR is a halogen-free flame-retardant polyamide which was developed for the electric and electronic industry. It is Blue Card certified and passes UL 94 burning tests with V0 for wall thicknesses from 3 mm onwards.
PA 2241 FR is a material developed for the aerospace industry which passes the FAR 25.853 tests.
PC is a thermoplastic material used widely for prototyping purposes which also has flame retardant properties, however in a lower rating than V0.
Ultem 9085 is a thermoplastic material which is applied in aerospace applications and reaches the UL 94 V0 flame retardancy rating.
