Materials supplier Evonik (Chinaplas booth 17-D87) is boosting capacity in China for its polyether block amide (PEBA) copolymer elastomers in China. Construction will commence in the fall of 2023 with completion slated for one year later. Together with a debottlenecking in Marl, Germany, overall capacity for PEBA will double.

PEBA is used widely in midsoles of sports shoes, and ski and hiking boots on account of its superior low temperature flexibility properties, but it also finds use in automotive applications such as airbags and noiseless automatic transmission gears, where it is blended with plastics such as polyacetal, according to Janny Ji, director of PA 12 Granules and Compounds at Evonik. PEBA is also used in hydraulic pressure lines for trucks.

Evonik is also developing applications for its Vestamid polyamide (PA) 12 resin in the new energy vehicle (NEV) market. "PA 12 has a long history with fuel lines [for internal combustion engine vehicles] in terms of chemical and thermal properties. As we transition to new energy vehicles, we believe the same properties will be important for battery cooling," said Senior Vice President Christina Walkosak, Product Line Granules & Compounds at Evonik.

Other Evonik highlights at Chinaplas directed at the NEV market include:

Chinaplas 2023 runs from April 17 to 20 at the Shenzhen World Exhibition & Convention Center.
