PA6 – Polyamide 6 PA6 + PP GF25
AKROMID® B3 GF 25 1 L black (4637)AKROMID® B3 GF 25 1 L black (4637) is a PA6/PP-blend with reduced density compared to standard PA6 with 25% glass fibre reinforcement. The material is suitable for components with high strength and stiffness where cost and weight reduction are required at the same time. The chemical resistance of AKROMID® B3 GF 25 1 L black (4637) is particularly superior to calcium chloride (CaCl₂).

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.
