FORTRON 1140E7 | PPS | Glass Reinforced
 
Description
Fortron 1140E7 is an inherently flame-retardant grade exhibiting extremely low flash and fast cycle times. It has excellent electrical properties, high hardness and stiffness. This grade exhibits good high-temperature load-bearing capabilities. It is especially used for thinner walled and longer flow length parts requiring low flash behavior. Good weldability due to a modest filler level. Commonly used in electrical connectors and and other thin wall/long flow length parts.
 
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
