CRP Technology Windform® FR1 Carbon Filled Flame Retardant Composite Polyamide for Additive Manufacturing
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer; Thermoplastic; Nylon (Polyamide PA)

Material Notes: Windform® FR1 is a carbon fiber reinforced Flame Retardant (V-0 rated) material for Additive Manufacturing, processable by Selective Laser Sintering. It passed the FAR 25.853 12-second vertical and 15-second horizontal flammability tests as well as the 45° Bunsen burner test successfully. It is a halogen free polyamide based material that combines superior mechanical properties with excellent stiffness and light weight.

Applications: Aircraft and Aerospace applications (interior parts, cockpit, cabin components, air conditioning piping, air ducts, air outlet valves); Automotive and Transportation parts (vehicle interiors, housing and enclosure assemblies, air ducts, air outlet valves), Consumer goods and Electronics (lighting, appliances) and in general for any parts requiring flame retardancy. It is also suitable for the manufacturing of components with detailed surface resolution.
