Stronger shielding. Less material.

This is EMI shielding that helps manufacturers cut material use, reduce processing wear, and keep weight down. No compromise on performance.

High performance at low filler content

  • Achieves 30–60 dB shielding effectiveness at just 1–1.5% volume – enough to meet most automotive EMC specs
  • Requires fewer fibers than carbon-based alternatives, reducing compound weight and improving mechanical consistency
  • Lower filler content improves melt flow, minimizes impact on shrinkage and impact strength, and supports greater design freedom

Tested where it counts. Proven where it matters.

Shielding that holds up – not just in lab tests – but during everyday use.

From engine bays to dashboards, modern plastic parts face heat, vibration, and chemical exposure – often all at once. Beki-Shield® GR is engineered for reliability under harsh conditions.

  • Excellent thermal and electrical conductivity to ensure uninterrupted shielding
  • Long-term mechanical and electrical stability – no sloughing, no degradation over time
  • Effective in both near-field and far-field EMI environments, across a wide frequency range
  • Stable performance through processing, moisture, and thermal cycling

Drop-in ready. Built for how you work.

You don’t need a new process to get better performance. You just need a better filler.

No need to reinvent your setup. Beki-Shield® GR is designed for drop-in compatibility with your existing compounding and injection molding lines.

  • Compatible with standard thermoplastics
  • Reduces tool wear compared to carbon fillers, extending machine uptime
  • Easy to disperse at low shear levels, preserving fiber length and maximizing network formation
  • Supports both masterbatch and direct dosing workflows
