FORTRON 4184L4 | PPS | Mineral / Glass Reinforced
 
Description
Fortron 4184L4 is the strongest and toughest glass/mineral reinforced product available. It offers excellent heat resistance at high loads and good chemical resistance. The electrical properties are excellent and the product is inherently flame-retardant. This product also offers low creep resistance and good rigidity due to the mineral content. Applications made of this grade include electronic components (i.e. bobbins, connectors and solenoid valves).
 
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
