RIGID SULPHUR FOAMS

RIGID SULPHUR FOAM IS A THERMOPLASTIC MIXTURE OF ELEMENTAL SULPHUR WITH VARIOUS VISCOSITY IMPROVERS, SURFACE ACTIVE SULPHUR WITH VARIOUS VISCOSITY IMPROVES SURFACE ACTIVE AGENTS, STABILIZERS AND BLOWING AGENTS. WHEN RELEASED FROM A PRESSURIZED VESSEL AS A MOLTEN FROTH, IT COOLS INTO A RIGID FOAM MATERIAL HAVING A CLOSED CELL STRUCTURE AND A UNIFORM DENSITY. ITS COMPRESSIVE STRESS APPEARS TO BE SUFFICIENT FOR MOST STRUCTURAL APPLICATIONS. IT IS NOT SENSITIVE TO LOW TEMPERATURES. IT HAS SEVERAL POTENTIAL APPLICATIONS IN HIGHWAY CONSTRUCTION. /AUTHOR/
