PPS 0205
 
FORTRON® 0205B4 SF3001 NATURAL
FORTRON® 0205P4 SF3001 NATURAL
 
FORTRON 0205 | PPS | Unfilled
 
Description
0205 is an easy flowing unfilled grade. It demonstrates excellent chemical resistance and thermal stability. Intended for compounding with various fillers. Available standard in pellet (0205P4) and powder (0205B4) form.
 
Other Processing
Injection Molding
On injection molding machines with 15-25 D long three-section screws, are usual in the trade, the unreinforced FORTRON is processable. A shut-off nozzle is recommended.
 
Melt temperature 310-320 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 (℃):110-120
