Celanese FORTRON 1140LC6 PPS, 40% Specialty
Categories:	Polymer; Thermoplastic; Polyphenylene Sulfide (PPS); Polyphenylene Sulfide (PPS) with 40% Glass Fiber Filler
Material Notes:	Fortron 1140LC6 is a 40% glass fiber reinforced material with a total chlorine content less than or equal to 900 ppm*. It offers excellent physical properties similar to those of the Fortron 1140L6 product. 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:	Low chlorine, 40% GF
