EMI Absorber Sponge

EMI Absorber Sponge

  • EMI-Microwave-Absorber-Sponge-1
  • EMI-Microwave-Absorber-Sponge-2
  • EMI-Microwave-Absorber-Sponge-3

Overview

  • Open cell polyurethane sponge coated with electromagnetic wave absorbing material
  • Electromagnetic wave absorbing material is uniformly coated inside and outside of the sponge, thus it can be uniformly absorbed even in the thick product.
  • Available to manufacture various products by cell density and thickness of sponge.

Features

  • RoHS Compliant
  • Excellent absorption rate of electromagnetic waves
  • Superior flexibility and elasticity due to polyurethane sponge characteristics
