B3 GF 30 4 L black (7481)PA6 + PP GF30

AKROMID® B3 GF 30 4 L black (7481) is a PA6/PP-blend with reduced density compared to standard PA6 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® B3 GF 30 4 L black (7481) is particularly superior to water glycol. This compound fulfills the requirements of VW TL52682 (1000h/135°C; 50/50 G12 EVO/water) and can be used for applications that are in contact witch cooling water.
