Stronger ESD protection. Fewer compromises.

Static discharge is a small spark that can cause big problems – damaging components, interrupting performance, and creating safety risks. Beki-Shield® BU builds ESD protection into your plastics from the inside out, so there’s no need for surface coatings or workarounds. Just clean, consistent conductivity that fits your process and your product.

Reliable ESD protection that starts at the fiber

Beki-Shield® BU is a stainless steel fiber solution for ESD protection and electrostatic discharge control in conductive plastics. Used in masterbatches or direct compounding, it forms a conductive network within the plastic, preventing static buildup and discharge. It works quietly in the background—so your components don’t make any noise.

Low volume. High reliability.

Unlike coatings that wear away or treatments that degrade, this conductivity is built into the plastic itself. The stainless steel fiber network is stable and designed to perform throughout the life of the part. No retesting, no rework, no compromise.

Effective protection. Minimal filler.

  • ESD protection at just 0.25–0.5% volume
  • Conductivity in the range of <10² Ω·cm
  • Lower impact on mechanical properties and aesthetics than carbon-based fillers

Durability that doesn’t short out under pressure

From castor wheels to circuit housings, your parts need to survive friction, impact, and everyday wear. Beki-Shield® BU delivers ESD protection that doesn’t give up when the plastic is under pressure.

Because ESD protection should last as long as the part it's built into. Not a day less.

  • Maintains consistent conductivity over the lifetime of the part
  • Withstands repeated cleaning, movement, and handling without degradation
  • No risk of surface flaking, discoloration, or conductivity loss from wear

Easy to integrate. Easier to trust.

Beki-Shield® BU was built to slot into your process, not slow it down. That means fewer adjustments, fewer surprises, and faster time to production.

  • Works with standard compounding and molding processes – no extra training or special equipment needed
  • Compatible with a wide range of polymers and dosing strategies
  • Less abrasive than carbon fibers, reducing wear on screws, barrels, and dies

Guidance from first trials to final parts

We support your team at every stage, from testing compatibility to optimizing your mix. Developing a new compound? Scaling up production? We work with you to make sure Beki-Shield® BU fits seamlessly into your process and delivers the performance you need.
