PP – Polypropylene PP GF25+M15

AKROLEN® PP GFM 25/15 black (1415)

AKROLEN® PP GFM 25/15 black (1415) is a 25% glass fibre reinforced, 15% mineral-filled polypropylene with good surface and dimensional stability

Typical applications

Thin wall housings for electronic parts in the automotive industry with operation temperatures up to 100°C

Processing information

The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.


6 Drying time 2 h

Drying temperature (τ ≤ -30°C) 80°C

Processing moisture ≤ 0,2%

2 Temperature zone 1 - Zone 4 200 - 255°C

3 Nozzle temperature 200 - 255°C

4 Melt temperature 215 - 265°C

5 Mold temperature 30 - 80°C

P Nach Holding pressure, spec. 300 - 800 bar

P Stau Back pressure, spec. 50 - 100 bar

Injection speed high

Screw speed 5 - 15 m/min

Warning

AKROLEN® PP can be processed on all injection molding machines with standard screws as per recommendation of the machine manufacturers. Please see our recommendations for the settings of machines, tools and dryers at the graphic below. Pre-drying is normally not required, unless the moisture content exceeds 0,2%.
