Positive impact of China's automotive/packaging sectors China may have forecast a lower growth rate this year, but companies interviewed at the recent Chinaplas show in Shanghai are still expanding, against the back of the burgeoning packaging and automotive sectors and the country’s 13th five-year plan that will stimulate a new round of consumption and industrial upgrade. The show closed with a total of 3,323 exhibitors and 148,575 visitors from 160 countries and regions.
Automotive sector drives growth for polymer firms With the global automotive market demand mainly driven by China, which has accounted for nearly 35% of global light vehicle sales in 15 years, it is little wonder that German speciality chemicals firm Lanxess is rooting for business in China/Asia. In fact, in 2015, its sales in China represented nearly half of the total in Asia Pacific. “We were successful last year, and this year has started promisingly, driven by the Chinese automotive market,” said Milan Vignjevic, Head of Sales & Marketing for High Performance Materials (HPM) in Asia Pacific. The HPM business unit makes Durethan polyamide (PA), Pocan polybutylene Milan Vignjevic of Lanxess paints terephthalate (PBT) and a rosy picture for the company’s Tepex thermoplastic engineering plastics growth in fibre composites.

With increasing mobility, the trend is towards lighter, safer and more fuel efficient cars. Since the use of engineering plastics in cars in China accounts for only 35% of that in Germany, there is further high potential for metal replacement, said Milan. “We are working with Chinese customers in new projects targeting front ends, engine parts and structural parts.” One example of a serial application production in China is of IHU and injection moulding, which is a combination of inner high pressure forming of aluminium tubes and injection moulding using Lanxess’s Durethan PA. “The IHU technology provides excellent stiffness and strength, against side impact, while the injection moulded Durethan is filled with 60% glass fibres and is an ideal choice for metal-plastic replacement,” said Milan. The first use in the automotive industry is for a front end and instrument board carrier in MercedesBenz A-Class and B-Class models. As well, the recent megatrend of engine downsizing and turbocharging has caused increasing thermal stress to components such as air intake manifolds with integrated intercoolers or charged air ducts. Thus, Lanxess offers Durethan XTS (Extreme Temperature Stabilisation), which elevates the continuous service temperature of PA6 and PA66 up to 200°C and is an alternative to high-temperature polymers such as PPA or PPS.
Honda has introduced the world-first development of hybridmoulded rear bumper beam in the hydrogen electric vehicle. It is made of Lanxess’s Tepex fibre-reinforced thermoplastic composites with a PA6 matrix
Yet, another technology is Tepex fibre-reinforced thermoplastic composite sheets, with the company “flooded with enquiries” in Asia, according to Milan. The first use was in brake pedals and more recent applications include seat pans, front end and rear bumpers. A recent example is a hybrid-moulded rear bumper beam for
