Common materials—such as textiles in the form of fibers or fabrics, foamed rubber, foamed plastics, thin sheets of plastic, paper, corrugated cardboard, combustible dusts, dry grass and twigs, and wood shavings—are all examples of materials with large sutface areas in relation to their volumes. In a well-estabhshed fire, materials with relatively small surface areas, such as chunks of coal or logs, burn readily. 

Explosive reactions can occur between oxygen and a wide range of chemicals including organic compounds (such as acetone, acetylene, secondary alcohols, hydrocarbons), alkali and alkaline earth metals, ammonia, biological specimens previously anaesthetized with ether, hydrogen and foam rubber. 

Quite often, NBR adhesives are used to bond various kinds of gasketing (cork, fibre, foam, rubber, metal) to rigid superstructures, such as aircraft. Films cast from solution are often used to fabricate honeycomb structures for aircraft. 

Colloids are classified according to the phases of their components (Table 8.9). A colloid that is a suspension of solids in a liquid is called a sol, and a suspension of one liquid in another is called an emulsion. For example, muddy water is a sol in which tiny flakes of clay are dispersed in water mayonnaise is an emulsion in which small droplets of water are suspended in vegetable oil. Foam is a suspension of a gas in a liquid or solid. Foam rubber, Styrofoam, soapsuds, and aerogels (insu-... 

Aniline, which is used not only to synthesise drugs, pesticides and explosives but also as a building block for materials such as polyurethane foams, rubber, azo dyes, photographic chemicals and varnishes, is manufactured at a quantity of approximately three million tons each year [61]. The toxic effects of aniline include increased nitration of proteins in the spleen [62]. 

A substance which assists in holding the foam structure produced by whipping or frothing in the manufacture of latex foam rubber. 

Foam Rubber A product produced exclusively from a liquid base, e.g., latex. Latex foam has an interconnecting cell structure and is most commonly used for cushioning applications. 

STM is the basement rather than the top floor of a building. The microscope is placed in a little faraday cage, lined with foam rubber, for damping acoustic waves. 

Dunlop A process for making foam rubber which uses sodium fluorosilicate to coagulate the rubber particles and deactivate the surfactants. See also Talalay.

A fire involving foam rubber mattresses in a storeroom led to an unexpected and serious explosion. Subsequent investigation showed that an explosion risk may exist when the flammable smoke and vapour from smouldering of large amounts of foam rubber are confined in an enclosed space. Suitable strict precautions are recommended [1], Methods of quantitatively evaluating potential fire hazards from release rates of heat, smoke and toxic gases from heated foam rubber and plastics materials were developed, and their application to real situations discussed [2],... 

About 25% of polymerized styrene is in the copolyrner form. The largest volume copolymer is SBR (25% styrene, 75% butadiene-rubber), used for making tires, hoses, belts, footwear, foam rubber, rubber-coated fabrics, and adhesives. ... 

Polyurethane foams are lighter than foam rubber and have displaced many of its applications, such as in bedding, cushions, car seats, armrests, and crash pads. Laminates are used widely in clothing as padding. 

The sturdy 16 x 20 foot communication outposf was set up inside the much larger film area. For added safety, the floor was covered with inch-thick foam rubber. The furnishings included two bunk beds, walkie-talkie, telephone and switchboard, radio-telephone, an event log, a small desk, a worktable, chairs and a draped-off chemical toilet.
