Eccostock® SH
RIGID PLASTIC FOAM SHEET STOCK
Eccostock SH is a rigid polyurethane foam, which remains rigid and withstands high temperatures, for a short time even up to 163°C (325°F). Unlike most polyurethanes, Eccostock SH has an extremely low dissipation factor and low dielectric constant. It is a closed cell foam, pink in color.
