EMC-20PCL EMC Anechoic Absorber

EMC-20PCL EMC Anechoic Absorber

ETS-Lindgren’s EMC-20PCL is an ultra broadband absorber which has been optimized for EMC applications. Its design is an evolution of traditional pyramidal polyurethane absorber and combines carefully balanced dielectric properties with a special blunt-tip geometry that is suited for low frequency operation.

ETS-Lindgren manufactures EMC-20PCL from high quality, low density polyurethane foam. A double immersion process evenly impregnates the foam with a proprietary conductive carbon formula and fire retardant salts. This process optimizes absorber performance and provides an extra degree of protection against water and fire damage. After curing, the foam is precision-cut into a pyramidal configuration and a coating is added for a pleasing appearance. Fifteen individual quality assurance checks take place during production.

This absorber features blunt-tips, which allow for greater working space within the chamber, while reducing the chances of absorber tip damage.


New or Retrofit Chamber Installation

EMC-20PCL Anechoic Absorber can easilty be installed into either new construction, or as a retrofit to existing chambers.

Reduced Profile, Blunt-Tips

The EMC-20PCL has a reduced profile, providing the user for a greater working space withing the chamber. Blunt-tips on this absorber reduce the chance of absorber tip damage.

Non-Hygroscopic Substrate

The EMC-20PCL absorber is produced from a new, fire-retardant chemical formula that is non-hygroscopic. As a result, the absorber is not affected by moisture and will maintain its mechanical and RF performance over the life of the product.

Assorted Colors

The EMC-20PCL is now available in the original blue, black or white.

Performance Standards

EMC-20PCL absorber meets or exceeds MIL-STD-461D/E/F and RTCA-D0-160 performance requirements and is ideal for new installations or chamber retrofits. It provides an ultra broadband performance range of 80 MHz - 40 GHz.

Ultra-Broadband Performance

During the manufacturing process, our unique two-step impregnations are specially formulated to provide improved reflectivity performance below 200 MHz. This tuning is verified on each absorber piece in a large coaxial reflectometer which measures reflectivity vs. frequency from 20 MHz to 300 MHz to ensure consistency of performance.

Field Strength

EMC-20PCL can safely handle the most stringent commercial EMC radiated field strength of 200 V/m (or equivalent power density of 110 Watt/m2, 0.1 Watt/in2) continuous wave. Max. service temperature is 90o C (190o F, continuous).

Power Handling

EMC-20PCL has excellent power handling capability. This absorber has been proven to safely withstand up to 0.5 Watt/in2 CW power density in RF and microwave frequency ranges. Maximum Service Temperature Max. service temperature is 90o C (190o F, continuous).


This absorber meets the fire retardant standards of NRL 8093 Tests 1, 2, 3, MIT MS-8-21, UL 94, and DIN 4102-B2: Tests for Flammability. EMC-20PCL has an ASTM E84-84 flame-spread index of 35 and a smoke developed index of 450.
