PARA – Polyaramide PARA CF40
AKROLOY® PARA ICF 40 black (6128)
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.
