Eccostock™ PP

Eccostock™ PP

Due to the low dielectric constant, the materials are essentially transparent to electromagnetic energy. It offers excellent thermal insulation. Eccostock PP is lightweight and will return to its normal thickness after being compressed. It can be heat sealed to form blocks of material or to make contoured pieces that can be draped over complex objects. Eccostock PP can be used as radomes, blankets, and coverings where radar transparency is desired as well as spacer in electronic.
