Extrusion International 5-2018

PREVIEW 48 Extrusion International 5/2018 The new development from AKRO-PLASTIC with regard to a PA 6.6 substitution is called AKROMID ® B+. Rein- forced with 50 %glass fibres, this compound achieves the same strength at 80 °C as a conditioned PA 6.6 GF50 (115 MPa breaking stress). The stiffness of the conditioned material achieves as well almost the level from PA 6.6. A portfolio with 30 to 50 % glass fibre reinforced AKRO- MID ® B+ compounds is already available for sampling, a grade with 60 % glass fibres will follow shortly. For some time now there has been a development part- nership with Plasmatreat with regard to material devel- opment relating to plastic-metal composites. The AKRO- MID ® PST which has resulted from this, in combination with stainless steel, for example, achieves a tensile shear strength of well over 50 MPa. After intensive additional development of these compounds, we now have excel- lent adhesion to aluminium. This is over 30 MPa with an overlap area of 12.5 x 25 mm. As an alternative to hydrolysis-stabilised polyamide, AKRO-PLASTIC now presents with the compound AK- ROMID ® A3 GF 30 4 L black (4678) a new material with outstanding mechanical properties and hydrolysis resis- tance. The blend from PA 6.6 and PP provides excellent hydrolysis properties. The proportion of PA 6.6 is signifi- cantly reduced here and the material is also optimised for density and thereby provides an additional weight advantage. BIO-FED, a branch of AKRO-PLASTIC GmbH, produces and markets biodegradable and/or bio-based plastic un- der the brand name M·VERA ® . In order to meet the legal requirements in France and Italy, among other countries, BIO-FED provides compounds with a correspondingly high proportion of renewable raw materials (bio-based carbon content over 40%) and variable “end-of-life” scenarios such as OK compost INDUSTRIAL, OK compost HOME and OK biodegradable SOIL, which will also be presented to German-speaking trade visitors at Fakuma. AF-COLOR, also based in Niederzissen, is another branch of AKRO-PLASTIC and the specialist for color and additive master batches. It will inform the trade fair visitors about new chemical injection fluid agents for use in thin-walled packaging applications, which are produced in multilayer production processes or used in technical and structural applications. AF-COLOR will also present its new additive portfolio for PET packaging applications. AKRO-PLASTIC GmbH www.akro-plastic.com Hall B2, Booth 2209 (together with sister company K.D.
