humid conditions,” says d’Hooghe. D’Hooghe also points to the potential problems


of persuading specifiers who are more used to working with metals to switch to plastics. ForTii shows linear behaviour over a wide range of temperatures, so it is easier to design with, he claims. After the market launch of a polyphthalamide


9T, Ultramid Advanced N, at K 2016, BASF intro- duced another at Fakuma: Ultramid Advanced T1000 (this takes the company’s range of PPA polymers to three, since it already had Ultramid T KR, the original PA6T/6). This is actually a group of compounds based on PA 6T/6I. BASF says that within the Ultramid family, Ultramid Advanced T1000 is the product group with the highest strength and stiffness and with stable mechanical properties at temperatures of up to 120°C (dry) and up to 80°C (conditioned). BASF says that, with its partially aromatic chemical structure, the new material offers high resistance to humidity and to aggressive media, “outperforming conventional polyamides and many other PPA materials on the market.” (The company is not the first to offer a PA9T: one form of the polymer has been offered by Kuraray as Genestar for some time, mostly in Asia.) “New materials for metal replacement are the


key to developing the next generation of light- weight, high-performance components,” says Abdullah Shaikh, head of BASF’s global PPA team. “The demands on the materials have increased drastically in recent years, mostly because of trends such as ongoing miniaturization, higher efficiency


Teknor Apex says Creamid grades, currently available with glass fibre content of 35, 50, or 60%, exhibit dramatically improved property retention in comparison with similarly glass-filled standard PA 66 compounds. They cost around 30% less than high-performance polyamides such as PPA and PA 46 that have comparable performance


targets, and functional integration.” Target applications include thermostat housings


and water pumps, in fuel circuits and selective catalytic reduction systems, for actuators and clutch parts in cars as well as in coffee machines, as furniture fittings, and in construction applications such as water distributors, heating systems and pumps. The initial portfolio consists of heat-stabilised,


glass fibre-reinforced standard grades with reinforcement levels ranging from 30 to 60% for different stiffness, strength and toughness values; glass fibre-reinforced special grades with improved hydrolysis resistance with 35 or 45% glass fibre reinforcement, and a special long glass fibre-rein-

BASF’s Ultramid Vision semi-transpar- ent, semi-crystalline polyamide, first seen at Fakuma 2017, now has its first application, in a special glove for operatives in warehouses and other product handling facilities, which incorporates a scanning unit to read product codes. Ultramid Vision B3K allows light to pass through largely unhindered and impresses with its high transmis- sion rate and low light scatter. After injection moulding, metallic contacts are pressed into the polyamide and connected to the internal electronics. Due to the inherent toughness of Ultramid Vision, this process can be

executed without risk of stress whitening or even failure. In addition, Ultramid Vision allows a clear view of the status LEDs in the display area. As a result, workers have both hands free


and do not have to interrupt their work flow. Lanxess, meanwhile, has been working on grades suitable for infrared laser transmission welding, which it says is taking on increas- ing importance, for example in housings around sensitive electronics, where other types of welding are less suitable. The company recently introduced a new PBT that is transparent to infrared and which is also hydroly- sis resistant. This is an important accomplishment, since improve- ments in hydrolysis resistance normally go hand-in-hand with decreases in laser transmission.
