SHOW REVIEW | FAKUMA 2017


trims, inlays in car doors or centre consoles, and functional components such as air vents. Ultramid Vision combines high light transmission with low light scattering, which BASF claims makes it the first semi-crystalline polyamide suitable for production of semi-transparent or transparent components for exposure to chemi- cally challenging environments. The company said the new PA grade is also UV and temperature resistant, scratch-proof and flame-retardant, making it a suitable alternative to amorphous aliphatic PA, PC or SAN.

Ascend Performance Materials introduced Vydyne FR350J, a new high performance PA66 compound intended for electrical connectors used in unattended home appliances.


In addition to good electrical and flammability


properties, the company said Vydyne FR350J displays high ductility and a 15% elongation at break, which provides engineers with greater freedom when designing parts such as living hinges and snap fits. The unreinforced, flame- retardant compound also provides good melt flow and a broad processing window. “Home appliances are getting smarter and demand for these so-called ‘smart’ products continues to grow. That means they will incorporate more electronics and more connectors,” said Vikram Gopal, Ascend’s Vice President of Technol- ogy. “Vydyne FR350J will make sure that appli- ances are safe as well as smart.” Vydyne FR350J provides an RTI electrical rating

of 130°C and a UL94 V-0 flammability rating at thicknesses down to 0.4 mm. Finished moulded parts tested according to IEC 60335-1 achieve glow-wire end product test values of 750°C at all thicknesses. The flame retardant additive package is REACH


and RoHS compliant and exhibits low corrosion for improved electrical contact performance. ❯ www.ascendmaterials.com


BASF unveiled two new new specialty polyamides offering high gloss and semi-transparency, as well as introducing an enhanced barrier PBT for sensitive packaging applications such as coffee capsules. Ultramid Deep Gloss is said to combine the chemical resistance of a semi-crystalline PA with the glossy finish of an amorphous polymer and very good abrasion resistance. It is aimed primarily at automotive applications such as decorative

BASF said the new polymer will be available globally as an uncoloured base grade – Ultra- mid Vision B3K – or in custom coloured versions. It can also be coloured by the processor using BASF Color Solutions’ PA-based colour masterbatches. The new barrier PBT grade – Ultradur Barrier B 1520 FC – offers enhanced oxygen barrier for single-layer injection moulded food contact packaging applications. BASF says independent tests have shown oxygen transmission rates below the ISO 15105-2/DIN 53380-3 test standard limits. ❯ www.basf.com


Coperion’s ZSK extruder concept marked its 60th anniversary this year (the company is planning a number of events to mark that milestone over the coming months). The continuing development of what Coperion refers to as the “forefather” of all twin screw extruders was evidenced on the company’s stand at Fakuma in the form of its new involute screw and kneading elements. Coperion Director of Global Marketing Bettina


König said the involute elements, which use a new cross section, can deliver significant output and quality gains in certain specific applications. The company cites the example of highly filled polyole- fin formulations such as PP/PE with 70-85% CaCO3
