描述
Fortron FX32T4L is an unfilled, impact modified, and lubricated polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. As the lubricated version of Fortron FX32T4, this grade offers enhanced mold release and improved cycle times for high-speed production applications .
The impact modification provides significantly improved toughness and ductility compared to standard PPS grades, with 30% elongation at break and a Charpy notched impact strength of 10 kJ/m² . The excellent flow characteristics (melt flow rate of 27 g/10 min) enable the molding of complex thin-wall parts with long flow lengths .
The lubricated formulation offers several processing benefits:
-
Improved mold release for efficient demolding
-
Enhanced cycle times to increase production efficiency
-
Reduced friction during processing
As a linear, semi-crystalline PPS, Fortron FX32T4L provides high dimensional stability, excellent chemical resistance (insoluble in all known solvents below 200°C), and very low moisture absorption. The material is inherently flame-retardant .
