Fir is a product series of JIANYU, which provides a "Flame-retardant" solution for 3D printing filaments. It is impermeable and has a water absorption rate of less than 1% at room temperature. The material fulfills flame retardancy according to UL 94 V-0 (@2.0mm), and is suitable for applications and components that require flame retardancy. COCOON ASA-Fir is a thermoplastic engineering material with flame-retardance. The material fulfills flame retardancy according to UL 94 V-0 (@2.0mm) It has high strength, low shrinkage, strong interlayer adhesion, and good toughness. The great performance in both UV resistance, water resistance and thermal stability make it an ideal material in printing complex, ready-to-use components, including final parts, fixtures, functional prototypes with demanding geometries, as well as large-scale leisure architecture and sculpture parts.
