A3 GF 40 2 L black (7500)PA66+PP GF40

AKROMID® A3 GF 40 2 L black (7500) is a PA6.6-PP-blend with reduced density compared to standard PA66 GF 40. With 40% glass fibre reinforcement, the material is suitable for components with very high strength and stiffness where cost and weight reduction are required at the same time. The materials very good surface quality as well as the outstanding UV-stability make it the product of your choice for technical parts which are exposed to UV radiation. This grade can be used for fuel filters.
