FAKUMA 2021 – MATERIALS | EVENT PREVIEW


60%, with hardness ranging from 40 Shore A to 60 Shore D. The company has recently launched grades for automotive interiors, with performance testing for odour and emissions. A representative Dryflex Circular TPE grade, a 65 Shore A material for inlay mats with a recyclate content of 20%, showed a very low amount of VOC (60 μg/g) and FOG (594 μg/g). Dryflex Green TPEs is a family of bio-based elastomers containing raw materials from renew- able resources such as plant and vegetable crops. The series includes grades based on TPS and TPO technologies, with amounts of renewable content to over 90% and hardness from 15 Shore A to 60 Shore D. � www.hexpol.com


KD Feddersen Key features of the KD Feddersen display at Fakuma include the full line of PA66 materials from Ascend Performance Materials, which include unreinforced, reinforced, impact-modified and flame-retardant engineering grades. It will also be promoting its extended distribution agreement with Korea’s Hyosung, which now covers all of its Poketone polyketone grades (it previously focused on extrusion grades for compounding). � www.kdfeddersen.com


Lanxess Lanxess says it is putting sustainable material and lightweight solutions in the spotlight at Fakuma 2021. Developments include ISCC-certified product innovations in relation to its Pocan-brand- ed PBT compounds – such as Pocan ECOB3235 and flame-retardant ECOB4239, both of which are reinforced with 30% by weight of recycled glass fibres (mass balance method). The company is also expanding its range of


Tepex continuous-fibre-reinforced thermoplastic composites with the addition of particularly sustain- able variants. A new recyclable material features a combination of flax fabrics and bio-based PLA as a


matrix material. This yields surfaces with a brown, natural look that emphasise the natural origin of the compound. Its weight-specific strength is roughly at the same level as that of a conventional Tepex Dynalite, which is reinforced with glass-fibre fabric. The material could be used in sporting goods, interior parts for cars, and electronic housing components, for example. At Fakuma, Lanxess will also highlight light- weighting projects using its hollow-profile hybrid technology which enables metallic hollow profiles to be functionalised using injection moulding. A new halogen-free flame-retardant and unreinforced PA 6 compound will also be showcased. This is particularly suitable for the large-scale production of components with thin wall thicknesses such as terminal strips. � www.lanxess.com


Lehvoss Lehvoss will introduce the latest addition to its Luvocom XCF line of high performance carbon fibre reinforced compounds, a PPA-based product offering a strength of 425MPa, stiffness of 47GPa, impact strength of 100 kJ/m2 1.37 g/cm3


, and low density of . Intended for demanding metal


replacement applications, the new compound joins the existing PA66, PPS, PPA, and PEEK options. Also new is Luvocom 60-50097, a carbon fibre


reinforced PP that is said to offer an alternative to PA6 and PA66. It offers a strength of 170MPa, stiffness of 18GPa, and notched impact strength of 11 kJ/m2


. Unlike PA, it shows no decrease in performance in humid conditions. The company will also present its Luvocom 1105-50303 PEEK reinforced with hollow glass spheres. This offers a density of 1.01 g/cm3


and is aimed at structural


lightweight construction. The company will also show its recently devel- oped line of highly endothermic propellant masterbatches, which can be used with low dosages (from 0.1%) in injection moulding and extrusion. The new masterbatches are free from azodicarbonamide (ADC) so can be used in food or drinking water contact applications. � www.lehvoss.com
