KEBAFLOW LCP HF130 (FE 190203*)

KEBAFLOW LCP HF130 is a 30% short glass fiber reinforced LCP with very high heat resistance. The material is characterized by the following properties: Good flowability at thin wall thicknesses, very good toughness and strength, inherent flame retardancy, high heat deflection temperature (HDT ~300°C), good chemical resistance.



LCP - KEBAFLOW

Details

The trade name KEBAFLOW stands for a range of liquid crystalline polymers (LCP). KEBAFLOW’s outstanding flowability enables the realization of extremely thin wall thicknesses. KEBAFLOW LCP is inherently flame retardant and exhibits very high heat resistance and good aging behavior.

Pre-drying:

Dryer type: dry air dryer
Temperature: 150 – 170 °C
drying time: 4 – 6 h
Recommended max. residual moisture: < 0.01 %.

Recommended basic settings:

melt temperature: 335 – 345 °C
Mold temperature: 80 – 120 °C
With higher cavity temperatures, smoother surfaces and better flow properties can usually be achieved.
surfaces and better flow properties.

Injection speed: very high
Viscosity decreases with increasing shear. Thus, for parts that are difficult to fill, increasing the injection speed may be more effective than increasing the melt temperature.

Back pressure: 0 – 30 bar (spec.)

Screw: 3-zone screw with non-return valve
Nozzle: Open nozzle or shut-off nozzle (recommended)
Wear protection: Wear and corrosion protected according to machine manufacturer’s recommendation for LCP glass fiber reinforced

The most important processing instructions in brief:

– Ensure good drying! Ensure moisture content < 0.01%.
– Inject as fast as possible, if necessary use machine with pressure accumulator.
– Injection speed has a strong influence on the achievable flow path length
– Avoid excessively thick walls
– Ensure good venting
