PARA – Polyaramide PARA CF40

AKROLOY® PARA ICF 40 black (6128)

39000 MPa

280 MPa

35 kJ/m²

AKROLOY® PARA ICF 40 black (6128) is a 40% carbon fibre reinforced polyarylamid with good flexural strength and good tribological properties.

Typical applications

Components with high dimensional stability, independent from moisture content.

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.
