EccostockPP Flexible, Low Loss, Closed Cell Polyethylene Foam 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. It is tough and weather resistant.

Observed performance varies in application. Engineers are reminded to test the material in application. APPLICATIONS Eccostock PP can be used as radomes, blankets, and coverings where radar transparency is desired. It can also be used in a variety of electrical and microwave applications. With its low density and being closed cell, it finds uses in ocean buoyancy applications. It has been used as a spacer in antenna applications. AVAILABILITY Eccostock PP is available in two densities: 2 lb/ft(32 kg/m) and 4 lb/ft (64 kg/m). It is designated as Eccostock PP-2 and Eccostock PP-4.
