Microwave-assisted foaming of expandable polystyrene beads

Journal of Cellular Plastics, 2011
A novel method for obtaining polystyrene foam, which uses microwave as the source of energy for expansion process, is developed. In this article, a method to disperse target expansion agent using two-stage bulk polymerization and free radical suspension polymerization of styrene is described. Current and proposed research uses environmentally friendly

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. The burning time during the small

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 ...

Adhesives for bead fusion of recycled expandable polystyrene

Journal of Applied Polymer Science, 2002
AbstractExpandable polystyrene (EPS) is a plastic cellular material that is commonly used in the packaging industry. Its growing uses have led to environmental concerns over resource sustainability and the dwindling availability of landfill spaces. Although existing approaches to control and manage EPS wastes are available, much effort is still needed ...

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.

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 ...

Properties of hardened concrete containing treated expanded polystyrene beads

Cement and Concrete Composites, 1994
This paper reports the results of an experimental investigation into the properties of hardened concrete containing chemically treated expanded polystyrene beads. The results showed that the strength, stiffness and chemical resistance of polystyrene aggregate concrete of a constant density were affected by the water to cement ratio.

Effectiveness of Expanded Polystyrene (EPS) Beads Size on Fly Ash Properties

International Journal of Geosynthetics and Ground Engineering, 2020
The present study focused on laboratory investigation of fly ash mixed with expanded polystyrene (EPS) beads. Different sizes of EPS beads were mixed with fly ash to study the effect on maximum dry unit weight, cohesion, angle of internal friction, California bearing ratio (CBR) value, coefficient of consolidation, and permeability.

Mechanical properties of polymer-modified concretes containing expanded polystyrene beads

Construction and Building Materials, 2007
Abstract In this study, styrene-butadiene rubber (SBR) latex as a polymeric admixture was applied in lightweight expanded polystyrene (EPS) concrete. The effects of curing conditions and polymer-cement ratio on the compressive and flexural strengths of polymer-modified EPS concretes were investigated.
