Foam-in-Foam Polyurethane Composite

Journal of Cellular Plastics, 2002
Open-pore flexible polyurethane (PUR)foams with various pore sizes (1–8 mm)were used as 3-D filler to reinforce low-density, closed-cell PUR flexible foam. The final composite has a “foam-in-foam” structure. Compared to the unfilled PUR flexible foam, the composite exhibits considerable improvement on mechanical properties: with the same density, the ...

Pulverized polyurethane foam particles reinforced rigid polyurethane foam and phenolic foam

Journal of Applied Polymer Science, 2013
ABSTRACTPolyurethane consumption has been increasing in recent years, raising concerns about how to deal with the polymer waste. Post‐consumer rigid polyurethane foams or polyurethane foam scraps (PPU) ground into particles were utilized to strengthen mechanical properties of rigid polyurethane foam (PUF) and phenolic foam (PF). Viscosity of prepolymer

Polyurethane Foam in Postoperative Casts

Clinical Orthopaedics and Related Research, 1978
One-half inch thick polyurethane foam is recommended for use in postoperative casts to avoid complications seen with postoperative swelling. The polyurethane is placed over the operative area, over the dorsum of the foot, and the anterior surface of the leg.

The many uses of polyurethane foam

The American Journal of Surgery, 1976
Self adherent foam padding has unlimited opportunities for plastic and general surgical use. Skin blisters do occur but less often than with tape. It may also be used over the shoulder and scapula where other types of more invasive immobilization were usually necessary and has also been effectively utilized as postmammoplasty support, as facial and ...

NMR microscopy of polyurethane foams

Solid State Nuclear Magnetic Resonance, 1999
NMR microimaging has been applied to the characterization of foam materials, in order to understand their properties and gain deeper insight into their structures. The structure of "open cell" foams can be visualized with sufficient resolution to obtain the size and shape of cells, as well as their spatial distribution within specimens.

Immobilization of Cells on Polyurethane Foam

2006
In this chapter, protocols and details for the immobilization of a model cell onto polyurethane foam carriers are provided in order to facilitate the use of such systems in laboratory or industrial reactors. Polyurethane foam has recently acquired great relevance as a carrier for its good mechanical properties, high porosity, and large adsorption ...

Polyurethane spray foam burn

Burns, 2008
The increasingly widespread use of polyurethane spray foam cans have resulted in yet another potential mechanism for causing burns. Polyurethane foams form monolithic, selfflashing surfaces which effectively seal against leaks. It is the most efficient form of thermal insulation available.
