描述
Fortron 1140L6 DW is a 40% glass fiber reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade is an easier flow version of Fortron 1140L4, developed specifically for drinking water contact applications —the “DW” designation indicates its suitability for this purpose .
Fortron 1140L6 DW offers essentially the same mechanical characteristics as 1140L4 but with improved flow, making it especially suitable for thin-walled parts with long flow lengths . The material combines high strength, excellent heat and chemical resistance, and inherent flame retardancy.
As a linear, semi-crystalline PPS, it demonstrates excellent chemical resistance to all solvents below 200°C, acids, bases, automotive fuels, and petroleum fluids at elevated temperatures . It provides high dimensional stability with very low moisture absorption (0.02%) and is RoHS, PFOS, and PFOA compliant .
