Trelleborg completes the acquisition of leading South Korean manufacturer MNE Group, significantly enhancing its capabilities and capacity in the semiconductor sealing market.

Consisting of the companies Materials Nano Engineering and Materials Nano Solution, MNE Group is primarily a manufacturer of high-performance specialty seals for both aftermarket and original equipment manufacturers. The acquisition provides Trelleborg Sealing Solutions with new products and capabilities and established customer contacts with some of the most significant manufacturers in one of the largest local markets for semiconductors globally.

Among the new products brought into the Trelleborg portfolio are Nanopure® perfluoroelastomer (FFKM) and fluorocarbon (FKM) O-Rings which seal in key processes including chemical vapor deposition (CVD), etch, ash & stripping.

Trelleborg has also acquired chemical mechanical planarization (CMP) parts including liquid silicone rubber (LSR) and high-consistency rubber (HCR) rolling diaphragms to stabilize the grinding pad and wafer during CMP polishing processes.

Another product brought into the Trelleborg range is the most critical seal in chip manufacturing, bonded slit valve door seals comprised of dynamic rubber-to-metal bonded seals for wafer transfer chambers.
