Eccostock®SH
Rigid High Temperature Plastic Foam Sheet Stock
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.
FEATURES AND BENEFITS
• Rigid
• High Temperature Resistance
MARKETS
• Commercial Telecom
• Security and Defense

APPLICATIONS
• Eccostock SH is primarily used as a high-temperature structural member or thermal barrier in
electrical/electronic applications.
AVAILABILITY
• Standard sheets are 30.5 x 61 cm (12” x 24”) in thicknesses of 2.5 cm, 5 cm, 7.6 cm, 10 cm & 15 cm
(1”, 2”, 3”, 4” & 6”).
• It is available in bulk densities of 2, 4, 6, 8, 10, 12, & 14 lbs/ft³ (0.03, 0.06, 0.10, 0.13, 0.16, 0.19 & 0.22
g/cc).
• Eccostock SH is available in other thicknesses, sizes, and customer specified shapes upon request.
