Thanks to compliance with the UL94-V-0 standard, PA-FR can be used in areas where there is a risk of fire without any problems
One of the basic properties of all plastics is that they are generally flammable. Normally this isn’t a problem either, after all, who’s going to set fire to plastics?
However, there are areas in which plastics are often used because of their other material properties, but a fire hazard must be minimized as far as possible. A prominent example of this are fittings such as cabin components of aircraft, but the same applies to motor vehicles of all kinds, as well as to space rockets.
For such cases, we offer you 3D models made of flame-retardant materials. In addition to ULTEM™, which is processed using the FDM process, this also applies to the PA-FR, one of our 6 PA variants. Both materials meet the requirements of the UL94-V-0 fire protection standard and can therefore be proven to be flame-retardant.
Underwriters Laboratories has been testing materials since 1894
This standard is issued by Underwriters Laboratories (UL), from Northbrook, Illinois (USA), which has been in existence since 1894 and specializes in safety testing of products and materials.
In the case of the relevant fire protection standard UL94-V-0, the test procedure is based on a precisely defined one trial by fire in a Bunsen burner flame. The material must neither catch fire nor melt into burning drops after it has been immersed twice for 10 seconds each in a Bunsen burner flame that is self-extinguishing after a maximum of 30 seconds.
Processing in selective laser sintering
Like all PA plastics, PA-FR is also processed using selective laser sintering, also known as SLS printing. This widely used 3D printing process is based on the local fusing of individual layers of powder using laser beam. This moves exactly the structure specified in the CAD file in the (in this case PA-FR) powder, the 3D model is built up layer by layer.
