Innovative options to tackle static and ESD

Wittenburg Group company Witcom Engineering Plastics specialises in development and production of electrically conductive compounds based on a wide range of polymers. It says conductive POM (acetal) is gaining a lot of attention for semi-finished materials used during manufacturing and assembly of electronic components.

“We can produce conductive POM that our customers can extrude safely up to more than 200 mm thick slabs and rod stocks without any stress cracking or gas bubbles on cross sections during further machining,” says Christine Van Bellingen, Business Development Manager for Conductive Materials at the company.

“In another direction, motivated by the corona pandemic, our conductive TPE grades offer touch-free solutions as well as tight profiles and sealing solutions,” she says.

Witcom has customers in the automotive industry already using its radar absorption compounds in the latest radar systems for blind spot detection, cross-traffic alert and more. Opportunities are also seen across the broader EV sector. “While electrifica¬≠tion and digitalisation of cars generate more electro-magnetic interferences, the trend for lower energy consumption and light weighting calls for more plastics. Our latest generation of cost-effective EMI shielding plastics compounds clearly opens new perspectives for metal replacement as well as for metal coating alternatives,” says Udo Schwestka, Business Development Manager for Radar Absorbing Materials.
