Polyurethane foam sponge

At the Walter Reed Army Institute of Research, an enzyme immobilized polyurethane foam sponge to decontaminate the skin of chemical warfare agents in a wide variety of... 

As described above (see Section VILA), soluble ChE and oxime together detoxify OP compounds. These features were combined to developed a sponge product composed of ChE (FBS-AChE and EqBChE), organophosphate hydrolase (rabbit or bacterial OPH), oxime (2-PAM or HI-6), and polyurethane foam combinations for the removal and decontamination of OP compounds from medically important biological surfaces such as skin. This is an important extension of the bioscavenger approach to external decontamination and protection against organophosphate toxicity, since currently... 

Flexible and rigid foams are the most popular types of polyurethane made in the United States. Flexible foams are used for cushioning, as in mattresses, upholstered furniture, and automobile seats. Semiflexible foams are component of carpet pads, sponges, packaging, and door panels for automobiles. Rigid polyurethane foams are used to produce insulation for roofs, refrigerators, and freezers. The construction industry accounted for more than half of all the rigid polyurethane foam made in 2002, primarily for...

FIGURE 11.5 Simplified plan view of defoamer and filter elements in typical cardiotomy reservoir. Both defoamer elements are sponge-like open-celled polyurethane foams coated with PDMS-hydrophohed silica antifoam. Inner particle filter has pore sizes in range of 50-90 microns and outer filter has pore size of 40 microns. (After Servas, F.M., Gremel, R.F., Ryan, T.C.

Sevastianov [82] reports the preparation of an open-celled polyurethane foam chemically hydrophobed with a perfluorosiloxane as a suitable defoaming material for defoaming blood. This material was initially as effective as the same polyurethane sponge coated with a proprietary PDMS-hydrophobed silica antifoam for defoaming a solution of human albumin (supposedly the main foam stabilizing protein in blood). However, the effectiveness of the latter diminished relatively rapidly... 

Development of Novel "Sponge-Type" Sorbent for Elimination of CS Preparation of Ammonium Molybdophosphate - Polyurethane Foam (AMP-PUF) Composite and its Sorption Behavior... 

Abstract. Aiming to develop sponge-type sorbent, composite involving ammonium molybdophosphate (AMP) and polyurethane foam (PUF) was prepared. A 33 - 60 % (w/w) of AMP granule was kneaded with base-liquids of two-component rigid type PUF. The composite was able to selectively and quantitatively adsorb 0.5-500 pg of Cs from 10 mL solution containing 500 pg of Na, K, Mg and Ca as matrices ions distribution coefficient (kj) was 4.2 x 10 and 1.3x10 mL/g for without and with matrices, respectively. Maximum sorption capacity was of 42.9 mg/g.

This paper describes a method for improving hydrophilicity by using radiation-induced grafting of flexible polyurethane (polyether) foam with polar vinyl monomers. By this procedure, the normally hydrophobic material can be converted into a remarkably water-wettable sponge.
