ForTii® K11

Technical Datasheet | Supplied by DSM
ForTii® K11 by DSM is a lubricated polyamide 4T (PA4T) grade reinforced with 30% glass fiber. It is suitable for processing by injection molding. Possesses high mechanical strength, good processability, high dimensional stability and good flow versus halogen-free competitive PPAs. 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® K11 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 electrical and electronic components like terminal blocks, RAST, DDR3, FPC, I/O, SATA/SAS and DIN connectors, PCB components and in mobile phone components. Meets the highest MSL-level (MSL1) for SMT and ISO 1043 for PA4T.
