A New Potting Material — Expandable Polystyrene Bead Foam

Journal of Cellular Plastics, 1977
Many present-day electronic packages are designed using sophisticated and expensive circuitry. A potting material that could be easily removed with common solvents was needed to reduce the cost and time of reworking defective components in these units. Polystyrene bead foam (PSBF) appeared to have several advantages over conventional encapsulants such ...

Marine floating concrete made with polystyrene expanded beads

Magazine of Concrete Research, 1976
Synopsis The performance of concrete containing expanded polystyrene beads was studied in the context of marine floating structures and compared with that of concrete containing perlite, the latter being an ultra-lightweight aggregate used for marine applications.

Flame-retardant hybrid materials based on expandable polystyrene beads

Journal of Fire Sciences, 2020
A highly efficient flame-retardant hybrid foam material combining expandable polystyrene foam beads and a waterborne resin equipped with inorganic flame retardants is described. The resin and the inorganic fillers were varied, and the different compositions were investigated in small burner and cone calorimeter tests.

Energy Absorption by Expanded Bead Polystyrene Foam: Dependence on Fracture Toughness and Bead Fusion

MRS Proceedings, 1990
AbstractIncreased energy absorption and load result when the contact area between an object and a foam cushion is less than the foam area because of an increased foam deformation volume (i.e. “Load Spreading”). The deformed volume is trapezoidal (i.e. not prismatic) and is a function of the foam dimensions and the object geometry.

EFFECTS OF EXPANDED POLYSTYRENE BEADS ON THE STRENGTH PROPERTIES OF BRICK AGGREGATE CONCRETE

Malaysian Journal of Civil Engineering, 2022
Bangladesh's construction industry has grown significantly over the past two decades. The construction industry is progressing at a faster speed, which has raised the raw demand for building materials. Finding an alternative to natural aggregate in concrete casting as a partial replacement is a smart concept to protect natural resources.

Quantified research on the nonuniform distribution of expanded polystyrene beads in sandwich panels

Construction and Building Materials, 2020
Abstract Expanded polystyrene (EPS) concrete is a core material in sandwich panels, and EPS beads are widely believed to be nonuniformly distributed in the panels. However, the effectiveness of attempts to improve the homogeneity has been difficult to prove because of the lack of a direct method to quantitively evaluate a nonuniform distribution ...

Density and Strength Properties of Sand-Expanded Polystyrene Beads Mixture

GeoCongress 2008, 2008
Expanded Polystyrene ƒ EPS ≈ beads was utilized to develop a new geotechnical material, sand-EPS beads-mixture (SEM). Density tests, direct shear tests and compression tests were conducted to evaluate the density and strength properties of the SEM. Direct shear tests were conducted under 4 different vertical stresses (32.7, 50, 75, 100kPa).

Expanded Polystyrene Lost Foam Casting—Modeling Bead Steaming Operations

Journal of Manufacturing Science and Engineering, 2006
The retention of pattern voids observed in the production of expandable polystyrene patterns for lost foam casting can be traced to conditions developed during mold filling and subsequent steaming. Void formation and closure, or healing, was observed using high-speed video imaging through a clear acrylic sheet cut to match one-half of a test pattern ...

Experimental Studies on Bottom Ash and Expanded Polystyrene Beads–Based Geomaterial

Journal of Hazardous, Toxic, and Radioactive Waste, 2016
AbstractBottom ash is a by-product produced from burning of pulverized coal in thermal power plants. The increasing production of bottom ash and its disposal in an eco-friendly manner is a matter of concern. This paper concisely describes the suitability of bottom ash to be used in civil engineering applications as a way to minimize the amount of its ...
