AKROMID®

A3 GF 40 1 L black (4671)

PA66 + PP GF40

AKROMID® A3 GF 40 1 L black (4671) is a PA6.6-PP-blend with reduced density compared to standard PA66 GF 30. With 30% 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® A3 GF 40 1 L black (4671) is particularly superior to zinc chloride (ZnCl₂).
