Since 1992, SIEPEL has been designing, manufacturing and setting up a wide range of electromagnetic absorbers. Very innovative, it is also the widest range on the market.

Thus, we have developed ASI & APU: elastomeric absorbers adjustable to frequencies between 1.5 GHz and 24 GHz.

These absorbers offer following remarkable physical properties:

  • Flexibility: easily manageable products
  • Mechanical resistance: excellent ageing resistance
  • Chemical resistance: good performance in saline environment
  • Power handling: 0.9 W/cm² CW max
  • Temperature resistance: from – 60°C to +140°C
  • Notable reflectivity performances and resistance over time
  • Compliance with environmental standards: raw materials in accordance with REACH & RoHS standards


Moreover, throughout the manufacturing process, our absorbers are submitted to numerous factory tests, as defined by our quality management system. Indeed, our products follow a rigorous checking process, which allows us to engage ourselves in guaranteed performances.
