K FAIR 2019
Together with its sister companies K.D. Feddersen, M.TEC and PolyComp, as well as its own branches AF-COLOR and BIO-FED, the compounder AKRO-PLASTIC will show at K 2019 under the banner of “Plastic Solutions” what the companies of the Feddersen Group have to offer in the field of plastics. The compounder will not only present further product developments, but will also focus on application-specific solutions developed in cooperation with partner companies.
Plastic Solutions - a Holistic Concept for the Future
AKRO-PLASTIC at K 2019
Contact with drinking water
The compounder provides an overview of the materials from the AKROTEK® PK series and the AKROMID® T5 series, which meet the standards according to KTW/W270, ACS, NSF 61 and WRAS up to 85 °C.
The test reports comprise all product variations between AKROMID® T5 non-reinforced to 50% glass fibre reinforced in natural and in black, as well as AKROTEK® PK-VM 8 non-reinforced to 50% glass fibre reinforced, also in natural and black.
Substitution of PA 6.6
Polyamide 6.6 compounds are only available to a limited extent, due to the shortage of raw materials on the market which has persisted for years, and prices have risen constantly. Therefore, the compounder has set itself the task of modifying a PA 6 in such a way that it achieves comparable properties to a PA 6.6 as an attractive alternative.
Over the past few months, customers have approached the company with numerous specific test requirements, which have been passed with flying colors and are presented here.
Additive manufacturing
The processing of highly reinforced plastics compounds opens up new possibilities in additive manufacturing and is a core competence of AKRO-PLASTIC. The carbon fibre reinforced AKROMID® B3 ICF 30 9 AM is successfully being used by the IKV (Institute for Plastic Processing) in Aachen in the MDM (melt deposition modelling) process. Thanks to the improved thermal conductivity of the carbon fibre reinforced compound, the associated faster cooling speeds and the tight batch tolerance for highly reinforced plastics, a stable manufacturing process with high production speeds has been implemented.
A video illustrates the functional principle of this processing technology using a test specimen made of AKROMID® B3 ICF 30 9 AM.

Transportation / flame-retardant compounds
For the public transport sector, the compounder has expanded and improved its portfolio of flame-retardant compounds based on halogen-free flame-retardant additives. Regulation ECE 118 applies in buses. For this purpose, AKRO-PLASTIC has developed compounds with various glass fibre contents which meet the requirements of Annex 6, 7 and 8. This means that the materials can be used anywhere in the interior of buses.
Since the introduction of EN 45545-2, stricter, far more differentiated criteria have applied to the railway application area. Here, too, the compounder has products in its portfolio which meet the demands of the standard valid since March 2016 with the requirement sets R21 HL2, R22 HL3, R23 HL3, R24 HL3 and R26 HL3. These materials are best suited for small to medium-sized parts in the interior and exterior of the vehicle. Particularly strict specifications apply to larger components and seat shells. AKROMID® C28 GF 25 FRT is the first glass fibre reinforced polyamide to meet the requirements of EN 45545-2 R1 HL2, R6 HL2 and R7 HL2 as well as the American standard NFPA 130.

Expansion of the PPA product line
Besides the conventional PPA compounds based on PA 6T, AKRO-PLASTIC has expanded its portfolio with the new AKROMID® T9. These compounds, based on the homopolymer PA 9T, are particularly characterised by lower water absorption and thus more consistent mechanical performance. PPAs are mainly used where increased requirements for strength and stiffness at elevated temperatures are required. This is achieved by a higher glass transition temperature (Tg) of the polymer, which can often lie between 125 and 135 °C.
With the PA 6T copolymers mainly used, however, the Tg drops below 100 °C with water absorption, together with the mechanical load capacity. Due to the fact that AKROMID® T9 absorbs less than half of the moisture, the high Tg and thus the high mechanical strength are maintained at elevated temperatures and humidity.
Initial tests in direct comparison also show better flowability and faster crystallisation behaviour, which will facilitate the very complex production of PPA compounds.
Plastic/metal hybrid composite
An economical solution for lightweight construction with simultaneous high functional integration is a combination of plastic and metal. Media impermeability is also a necessary criterion for the quality of the bonding. Optimum hybrid components are obtained through the combination of an applied plasma layer and targeted modification of the plastic.
In order to fully exploit the potential of plastic/metal hybrid compounds, AKRO-PLASTIC GmbH and Plasmatreat GmbH have entered into a cooperation which pursues the goal of realising a material-formed bond between plastic and metal in a closed process.
An innovative project, which was developed together with K.A. Schmersal GmbH & Co. KG in Wuppertal, will be presented at K 2019. The Schmersal Group is a leading system and solution provider in the field of safety switchgear for the protection of people and machinery.
This is what we call metal substitution: Metal Substitution

Highly reinforced compounds
AKRO-PLASTIC has specialised in the production of highly reinforced engineering plastics with its in-house machine technology. The focus of these products is on achieving high mechanical performance and reproducibility. Gentle processing enables less glass fibre or carbon fibre breakage during compounding, resulting in slightly increased mechanical strength and impact strength compared to conventional products on the market.
Used and proven worldwide, the ICX® Technology with identical machines and processes ensures globally the same product quality and constancy, no matter on which continent it is manufactured. Especially in the case of highly reinforced plastics in demanding applications, these properties offer advantages to both the design engineer and the person responsible for the parts in order to achieve the promised functionality safely, competitively and sustainably.

Branches of AKRO-PLASTIC
BIO-FED & AF-COLOR at the K 2019
BIO-FED, a branch of AKRO-PLASTIC GmbH, produces and markets biodegradable and/or biobased plastic under the brand name M∙VERA®. The product portfolio comprises biocompounds with a share of renewable resources ranging from 30 to 100%. In order to meet the legal requirements of the bioplastics sector in France and Italy, among other countries, BIO-FED offers compounds with a correspondingly high proportion of renewable raw materials (biobased carbon content over 50%) and variable end-of-life scenarios such as OK compost INDUSTRIAL, OK compost HOME and OK biodegradable SOIL.
Possible application segments are:
Biodegradable compounds for injection moulding applications (e.g. coffee capsules, drinking straws and disposable cutlery)
Compounds for the production of home-compostable films for starch-based bag applications (e.g. fruit and vegetable bags)
Compounds for the production of biodegradable films for agricultural applications (e.g. mulch films)
All M·VERA® compounds can be colored individually – for example with the AF-Eco® biopolymer based masterbatches which are certified by TÜV AUSTRIA Belgium in accordance with EN 13432. The AF-Eco® range consists of color and carbon black masterbatches as well as additive masterbatches.
