FORTRON 1342L4 | PPS | Specialty
 
Description
Fortron 1342L4 is a low wear grade, ideally suited for bearings, gears and other sliding friction/wear applications. This product is glass fiber reinforced and contains PTFE.
 
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
