In January, CRP Technology kicked off the year with the launch of Windform® P2, a glass fiber reinforced thermoplastic polyamide material. The Italian producer continues its material developments with the release of Windform® FR2, another composite material from the TOP-LINE family compatible with the SLS technology.
Unveiled in July 2019, the Windform® FR1 is carbon fiber-reinforced flame-retardant material that is similar to the company’s new material in terms of flame-retardance.
The main differences between both materials are their properties: the Windform® FR1 is carbon fiber reinforced and dark gray with regards to color.
The Windform® FR2 on the other hand, is glass fiber reinforced, off-white with regards to color, and electrically insulating. Furthermore, this product is a halogen free polyamide-based material, which combines outstanding wear resistance and good temperature resistance. It delivers accurate parts with smoother surface finish when compared to Windform® FR1.
The producer has carried out the FAR 25.853 12-second vertical and 15-second horizontal flammability tests as well as the 45° Bunsen burner test and Smoke density test which happen to be successful.
“Flame retardants are not new to the 3D printing market but flame-retardant materials which were also reinforced and presenting significant mechanical properties, lacked. (…) In order invent these materials, we must anticipate, intercept and satisfy the requests of the most demanding and innovative industrial sectors”, commented Franco Cevolini, VP and CTO at CRP Technology –
Owing to its flame-retardant quality and insulating properties, Windform® FR2 is suitable for Aircrafts and Aerospace applications, Automotive parts (casings of electrical and electronic components, housing and enclosure assemblies), Consumer goods (lighting, appliances) and in general for any parts requiring flame retardancy.
