according to Joe Allbritton, technical service associate for the Teknor Color Division. ‘TekTuff concentrates are available on a custom basis, including new colour matches as well as any existing colour’, he says. Allbritton also reveals that the company intends to develop similar TekTuff technology for use with styrenic resins. Teknor Apex, a privately held firm founded in 1924, produces flexible and rigid vinyl, thermoplastic elastomers, nylons, toll and speciality compounds, colour masterbatches, speciality chemicals, bioplastics and hoses. The company is headquartered in Pawtucket, RI, USA, and operates 13 facilities worldwide in the USA, the Netherlands, the UK, China and Singapore. The Teknor Color Division produces colour concentrates for use in all thermoplastic processes. Contact: Teknor Apex Co, Pawtucket, RI, USA. Tel: +1 401 725 8000, Web: www.teknorapex.com
Gabriel-Chemie presents new metallic effect and flame retardant products
A
ustrian firm Gabriel-Chemie GmbH has developed new masterbatch solutions for injectionmoulded parts with a metallic look. According to the company, the new products offer improved flow line properties and therefore reduce timeconsuming and costly post-treatment. A new series of low- and no-halogen flame retardant masterbatches has also been introduced. The new metallic effects from Gabriel-Chemie unite ‘aesthetic surfaces, reduced flow lines and cost optimization’, the company claims. They are simple to process and visibly upgrade plastic products, it says. The masterbatches reportedly allow ‘almost unrestricted freedom of design, even with complex geometries’. With their use, flow lines can be significantly reduced in the production of injection-moulded parts and the optical appearance of the component can be considerably improved, while visually perceptible surface defects resulting from streaking are avoided, it reports. Through the targeted optimization of the metallic effects it is now possible to avoid the use of paints, coatings or labels, according to Gabriel-Chemie. In some cases it is even possible to completely replace

metal parts, it claims. Metallic effect plastics are used in household, office and decorative articles, electronics, telecommunications, sports and leisure applications. Whether for the interior equipment of cars, electrical cables or entertainment electronics, the use of flame retardants is absolutely necessary in order to ensure the safety of the consumer. Gabriel-Chemie has ‘many years of experience with optimum solutions’ for this sector and now offers halogen-free flame retardant masterbatches for both thinwalled applications (polyethylene and polypropylene) and thick-walled applications (polypropylene), it reports. The new series includes both low-halogen and 100% halogen-free products. According to the company, its new product range offers ‘a wide variety of complete solutions’ and is ideal for ensuring adherence to certain fire protection standards, for enabling good compatibility with common UV stabilizers and thus for guaranteeing suitable protection of the plastic. It also enables easier processability, higher flexibility in colouring and advantages in mechanical properties, Gabriel-Chemie claims. Typical areas of application for these flame retardant masterbatches are films, tapes, pipes and fibres for outdoor and indoor applications, it reports. The company presented the new products at the Fakuma trade fair in October, where it also highlighted its range of ‘ecologically optimized’, HBCD (hexabromocyclododecane)-free flame retardant masterbatches for extruded polystyrene (XPS). Gabriel-Chemie also revealed its Colour Vision® No. 15 palette of future trend colours for plastics at Fakuma 2014. The range of 36 colour plates focuses on ‘chrome metallics’, ‘plastic science’ and ‘artificial symbiosis’. The new metallic shades ‘impress with a mirror finish and reflective surface’, while the company suggests that the colour plates in the ‘plastic science’ range should not only be looked at but also listened to and felt. The ‘artificial symbiosis’ range takes nature as a model and combines ‘material looks and experienceable surfaces’, it says. Polymers such as PP, COC and PS are used in the colour plates. Some of the exclusive colours are refined with special raw materials such as effect pigments, fibres and special additives, which were predominantly implemented in opaque colours but are also shown in some transparent versions, Gabriel-Chemie reports.
