材料文字说明

Fortron 1140L4 DW is a 40% glass-reinforced grade that is the strongest and toughest product available. It has been developed for use in drinking water applications.  It exhibits excellent heat and chemical resistance, good electrical properties and is inherently flame-retardant. The high hardness and rigidity at elevated temperatures allows for good load bearing performance. This product has good weldability due to the modest filler level. Applications made of this grade are electronical components (i.e. bobbins, lamp housings, brush holders) and various other components requiring strength and resistance to aggressive chemicals (i.e. automotive heaters, pumps, valves, fuel rails, microwave oven rings and distillation column packings).

注塑成型

Predrying in a dehumidified air dryer at 130 - 140 degC/3-4 hours is recommended.
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.
Tool temperature of at least 135 degC is recommended for parts to achieve maximum crystallizable potential.
