ForTii® F81

Technical Datasheet | Supplied by DSM
ForTii® F81 by DSM is a halogen-free, red phosphorous-free, flame retardant polyamide 4T (PA4T) grade reinforced with 15% glass fiber. Is suitable for processing by injection molding. Possesses improved flow and high dimensional stability. Shows fast crystallization, shorter cycle times, low moisture absorption, long term heat ageing performance and good weld line strength. Exhibits high thermal stability, high stiffness at elevated temperatures, high toughness, excellent chemical resistance and is also resistant against calcium chloride. ForTii® F81 is ideal for Surface Mount Technology (SMT) lead-free reflow soldering. It brings the second best moisture sensitivity level (MSL2) acc. IPC/JEDEC J-STD 020D for SMT in the most demanding applications. Used in automotive applications, electrical and electronic components. Meets the highest MSL-level (MSL1) for SMT and ISO 1043 for PA4T.
