CRP  Windform

(Viewing data as-entered. Click here to return)
CRP Technology Windform® FR2 Glass Filled Flame Retardant Composite Polyamide for Additive Manufacturing
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer; Thermoplastic; Nylon (Polyamide PA)

Material Notes: Windform® FR2 is a white, halogen free polyamide based material and is not electrically conductive. Windform® FR2 combines outstanding wear resistance with good temperature resistance. It allows for good detail resolution with smoother surface finish when compared to Windform® FR1. It passed successfully the UL 94 HB 1 mm and 3 mm rating, 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.

Applications: Owing to its flame-retardant quality and insulating properties, Windform® FR2 is suitable for Aircraft 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.
