Preliminary datasheet

PA6 – Polyamide 6 PA-Blend

AKROMID® C28 GF 25 FRT blue (7986)

11000 MPa

145 MPa

60 kJ/m²

C28 GF 25 FRT grey (7986) is a 25% glass fiber reinforced, halogen-free flame retardant and easy flowing polyamide blend with a blue color.

To achieve an excellent surface quality a mould temperature of at least 120 °C is necessary.

Typical applications

Public-Transportation, especially train seats

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.
