Eccostock® PP
FLEXIBLE LOW LOSS CLOSED CELL FOAM
Eccostock PP is a closed cell, cross-linked polyethylene foam with low loss, low dielectric, and low density. Due to the low dielectric constant, the materials are essentially transparent to electromagnetic energy. Dielectric constant does not change with frequency and change with temperature is negligible. 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.
