Eccosorb™ JCP-PP9

Eccosorb™ JCP-PP9

Eccosorb JCP-PP9 is an injection molded absorber grade based on a proprietary blended polypropylene based material made to match a typical automotive bumper’s physical properties. JCP-PP9 has been formulated to achieve significant reduction of electromagnetic interference through absorbing the energy in the 60+ GHz range. Its high impact resistance and compliance, typical of polypropylene, are a perfect match for many automotive, industrial, consumer, and military applications.

Features and Benefits

  • High loss
  • Low density
  • Impact resistant
  • High frequency radar applications, 76-81 GHz
  • Ability to economically manufacture complex shapes for higher volume products
  • Form 3D parts to fit available cavities without the limitations of 2D die cut materials
  • Due to the unique loading system, parts molded from JCP-PP9 feel and perform very close to the original polypropylene blend base material with exceptionally high EMI attenuation
  • Automotive imaging radar systems see a significant distortion of their signal, seen in the side lobe of the antenna pattern, because of reflections off the areas surrounding the radar unit, vehicle chassis and the vehicle bumpers. ReZorb with JCP-PP9 radar brackets absorb the incident signal greatly limiting reflections and limiting noise, false positives and false negatives in signal readings.
