New foaming agents lead to weight reductions of engineering plastics without a significant impairment of their properties. The use of mutually matched systems, e.g. the (PA+PP) Akromid Lite blend and the foaming agent masterbatch AF-Complex PE 990310 TM, is recommendable. In the case described here, the density of Akromid B3 ICF 201 Lite black (5296) was reduced by 13 % through the addition of a foaming agent. A further weight reduction of 8% was achieved by means of blend technology (PA+PP). Compared with polyamide 6 GF 30, an overall weight reduction of 30% was possible thanks to the innovative ICF carbon fiber from Akro-Plastic - in addition to higher tensile strength and bending resistance. Hereby, the density of this foamed compound is significantly lower than that of water (Title figure), and has a flexural modulus of more than 12,000 MPa.
