The EPP outdoor absorbers are a solid, expanded polypropylene absorbent material, under normal conditions and oblique incident electromagnetic area, it has excellent broadband wave absorption, and of the EPP material, it is also weather-resistant and suitable for outdoor use.

The base material of the flat foam absorbers is polypropylene mixed with carbon material and other additives. 

Compared to traditional polyurethane absorbent materials, the EPP rigid foam absorbent materials we produce are weather resistant and have the advantages of higher energy consumption, stronger usage intensity, improving the clean and hygienic environment of the whole chamber. The life of the EPP foam absorber can be up to 20 years.
