ECCOSTOCK® SH is a rigid, closed cell, polyurethane foam which remains rigid at high temperatures. ECCOSTOCK® SH may be used at a maximum service temperature of 275°F (135°C) and at 325°F (163°C) for short periods. It is primarily used as a high temperature structural member or thermal barrier in electrical/electronic applications.
Unlike most polyurethanes, ECCOSTOCK® SH has extremely low dielectric loss and The ratio of the capacitance (ability to store electrical energy) of a condenser filled with the material in question to that of the same condenser filled with vacuum.dielectric constant. The material is easily machinable and does not support fungal growth per MIL-STD-810E.
ECCOSTOCK® SH is also available as a two-part, foam-in-place liquid system called ECCOSTOCK® FPH. When cured, it has identical properties to ECCOSTOCK® SH of the same bulk density.
