PA6.6 – Polyamide 6.6 PA66+PA6I/6T LGF50

AKROLOY® PA LGF 50 natural (5504)

20500 MPa

290 MPa

115 kJ/m²

AKROLOY® PA LGF 50 natural (5504) is a 50% long glass fibre reinforced, semi-aromatic polyamide blend with extraordinary high stiffness and strength even at high temperature and very high impact and notched impact strength at elevated and low temperature even in conditioned state. PA LGF 50 natural (5504) distinguish due to isotrop mechanical properties, low shrinkage, higher heat deflection temperature and very good fatigue performance. The material has very good surface properties.

Typical applications

Technical components in the automobile and mechanical engineering industries.

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.
