FORTRON® 4332L6 SD3002 BLACK
FORTRON® 4332L6 SF3001 NATURAL
 
FORTRON 4332L6 | PPS | Mineral / Glass Reinforced
 
Description
Fortron 4332L6 is a glass fiber/mineral filled injection molding grade, which is intended for applications requiring improved tensile and flexural properties, when compared to other GF/MIN reinforced PPS grades. The recommended processing parameters are similar to the standard grades.
 
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.
