Celanese FORTRON MT9120L4 PPS, 20% Medical Technology
Categories: Polymer; Thermoplastic; Polyphenylene Sulfide (PPS); Polyphenylene Sulfide (PPS) with 20% Glass Fiber Filler

Material Notes: Fortron MT9120L4 Natural is a 20% glass fiber reinforced injection molding grade that exhibits excellent heat and chemical resistance, inherent flame retardancy, and high hardness and rigidity at elevated temperatures. Components made from this grade may
FORTRON should in principle be predried. Because of the necessary low maximum residual moisture content the use of dry air dryers is recommended. The dew point should be =< - 30° C. The time between drying and processing should be as short as possible.
For subsequent storage the material should be stored dry in the dryer until processed (<= 60 h).

Information provided by Celanese Corporation.

Key Words: 20% glass fiber reinforced injection molding grade that may be used for medical and food handling applications
