New and Extended Product Portfolios
High-quality appearance and lightweight design feature prominently on the booth run by Akro-Plastic GmbH, Niederzissen, Germany. The company has developed Akroloy Para ICF 40, an aromatic polyamide with very good flowability (PA MXD 6). Even with 40 % carbon fiber reinforcement, high surface quality with strength values similar to that of metal can be achieved. According to the manufacturer, the surface quality is so high that components can be fitted unpainted in the BMW 7 series.
Two new grades in the Akromid-Lite range (based on PA with chemically coupled PP) not only save weight but also offer improved properties and good adhesion to olefin-based TPE grades. The long glass fiber-reinforced polyamide blend Akromid B28 LGF 40 1 L is said to have superior strength values to a short glass fiber-reinforced polyamide with 50 % glass fibers, even at 120°C. Akromid B3 ICF 20 1 L offers good mechanical properties comparable with those of unreinforced PA, coupled with light weight that can be further reduced through the use of chemical blowing agents.
For the backrest cover and other applications for a bus seat, halogen-free, flame-retardant Akromid B3 GF 25 9 (6360) has been developed in collaboration with the seat manufacturer, Franz Kiel GmbH, Nördlingen, Germany. This grade has low flammability, good flow properties and surface replication and meets the requirements of UN/ECE R118 Appendix 8. For the railway sector, Akro offers the unreinforced PA6, Akromid B3 1 FR black (5983), in its portfolio, a product approved under European railway standard EN 45545-2 (R22/HL3, R23/HL3 & R26/HL3). Supplied to meet the requirements of standard EN 45545-2 R24/HL3, Akromid B3 GF 30 FRT black (6665) is listed under UL94 HB (0.8 to 3.0 mm) and also f1 listed. In the aerospace sector, the compound Akroloy PA K17 FR black (5762) can be used. This grade is specified for interior aerospace applications under Federal Aviation Regulation (FAR) 25.853. It has low smoke density, toxicity, and flammability and can be used for structural components.
Under the trade name Precite, the compounder is marketing a new range of PBT and polyethylene terephthalate (PET) compounds and various polyester blends. The portfolio focuses on reinforced grades with up to 50 % glass fibers. Blends of PBT/ASA and PBT/SAN (styrene-acrylonitrile copolymer) are also available – these have lower warpage and are therefore suitable for larger components. For applications with high surface requirements, compounds based on PBT/PC and PBT/PET complete the portfolio. This product line also includes ICF grades with cost-competitive carbon fiber reinforcement. Besides offering high strength and elongation at break, the ICF compounds reduce the component weight by 10 to 20 %, depending on the grade. The material is suitable for precision parts in lightweight design and electromobility applications.
With AF-Clean Basic (180–240°C) and AF-Clean HT (240–350°C), AF-Color, a subsidiary of Akro-Plastic, is introducing its new AF-Clean range of purging compounds. In addition, an additive masterbatch known as PE 990407 TM has been developed, which actively promotes the formation of gas cells (nucleation) throughout the whole polymer melt. This leads to significantly more foam cells without reducing the melt viscosity necessary for an effective foam formation process.
