PPS 1120L4 含20%玻纤增强,耐热,耐化学
FORTRON® 1120L4 SF3001 NATURAL
FORTRON 1120L4 | PPS | Specialty
Description
Fortron 1120L4 is a 20% glass fiber reinforced injection molding grade exhibiting excellent heat and chemical resistance, inherent flame retardancy, high hardness and stiffness at elevated temperatures.
Other Processing
Injection Molding
On injection molding machines with 15-25 D long three-section screws, as are usual in the trade, the FORTRON is processable. A shut-off nozzle is preferred to a free-flow nozzle.
Melt temperature 320-340 degC
Mold wall temperature at least 140 degC
A medium injection rate is normally preferred. All mold cavities must be effectively vented.

Processing
Pre Drying
Necessary low maximum residual moisture content: 0.02%
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℃. 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).
Drying time (h):3-4
Drying temperature (℃):130-140
