High-Reliability EMI Shielding & Environmental Sealing Solutions

providing reliable solutions for electromagnetic compatibility (EMC), environmental sealing, and long-term product reliability across multiple industries

professional solutions and customised solutions

  • Epoxy Potting Compound

    Ultra-low resistivity with effective EMI shielding and environmental sealing. Designed for reliable performance from −55°C to +170°C, offering excellent flexibility, mechanical durability, and multiple form factors including sheets, molded parts, and extruded profiles.

  • Silicone Potting Gel

    Thin, soft, and crack-resistant for installation in confined spaces. As an insulating absorber, it must be bonded or compressed to a metal substrate for optimal performance. Optional adhesive backing (>60 kPa peel strength) and custom die-cut shapes are available. Lower operating frequencies require greater thickness and weight.

  • PU Potting Compound

    Fast surface curing and rapid formation improve production efficiency. Delivers excellent EMI shielding performance exceeding 90 dB, with room-temperature curing to avoid thermal impact on components. Reduces material waste and assembly labor while eliminating costly tooling and supporting rapid prototyping.
