NEWS Covestro makes a circular call
Covestro said it is working with Fairphone, a Netherlands-based social enterprise aiming to build a market for sustainable and repairable smartphones, on the use of circular and recycled materials. Fully and partly recycled TPUs from
Covestro’s Desmopan range are specified for the protective covers of the Fairphone 3 and new Fairphone 4, including Desmopan 3095AU RC100, which is sourced from post-industrial streams of recycled plastics. The materials are certified according to Recycled Claim Standard for traceabil- ity of recycled raw materials. “The fully recycled material exhibits the typical advantages of TPU, for example, high chemical and abrasion resistance, but easier processability because it melts at lower tempera- tures and flows better than virgin
to virgin material in terms of impact strength, stiffness, flame retardancy
and flow, while reducing CO2 emissions by 30%. n Separately, Covestro and biotech firm Genomatica announced they have produced “significant volumes” of bio-based hexamethylenediamine (HMD) during their joint work to develop a commercial process technology. HMD is a key raw material for the

material,” Covestro said. The new Fairphone 4 model also contains 30-50% post-consumer recycled Makrolon PC in the rear cover, middle frame and wireless charger. The PC grade used is said to offer physical properties comparable
production of PA66 polymer. The two companies now plan to
proceed to full commercial scale manufacturing and Covestro has secured an option to license Genom- atica’s GENO HMD process technol- ogy for this purpose. �

MK connects with Ultradur PBT
MK-Elektronik developed its new C-Klic automotive connector system using Ultradur B 4300 G4, a glass reinforced grade of PBT from BASF. The new design is said to provide a space saving of up to 60% compared to standard USB ports while supporting data transfer rates of >10GB/s and providing a USB power delivery option. Ultradur is used to produce the CPA element, coding housing and internal overmoulding in the new design. �
