FORTRON® 1140L7 SF3001 NATURAL
FORTRON® 1140L7 SY3004 BROWN
 
FORTRON 1140L7 | PPS | Glass Reinforced
 
Description
One of the easiest flowing 40% glass reinforced grade in the Fortron product line. This material can be processed at fast cycle times due to the unique crystallization characteristics. This product offers good heat and chemical resistance, as well as, good electrical properties. The product is inherently flame-retardant and exhibits high hardness and rigidity.
 
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
