FORTRON® 1141L4 SD3002 BLACK
FORTRON® 1141L4 SF3001 NATURAL
 
FORTRON 1141L4 | PPS | Glass Reinforced
 
Description
Fortron 1141L4 is a 40% glass-reinforced PPS that has excellent heat and chemical resistance, inherently flame-retardant, high hardness and a good balance of strength and stiffness. This grade exhibits low flash and is typically used in applications with thicker walls and shorter flow lengths.
 
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
