In suspension processes the fate of the continuous liquid phase and the associated control of the stabilisation and destabilisation of the system are the most important considerations. Many polymers occur in latex form, i.e. as polymer particles of diameter of the order of 1 p.m suspended in a liquid, usually aqueous, medium. Such latices are widely used to produce latex foams, elastic thread, dipped latex rubber goods, emulsion paints and paper additives. In the manufacture and use of such products it is important that premature destabilisation of the latex does not occur but that such destabilisation occurs in a controlled and appropriate manner at the relevant stage in processing. Such control of stability is based on the general precepts of colloid science. As with products from solvent processes diffusion distances for the liquid phase must be kept short furthermore, care has to be taken that the drying rates are not such that a skin of very low permeability is formed whilst there remains undesirable liquid in the mass of the polymer. For most applications it is desirable that destabilisation leads to a coherent film (or spongy mass in the case of foams) of polymers. To achieve this the of the latex compound should not be above ambient temperature so that at such temperatures intermolecular diffusion of the polymer molecules can occur. [Pg.181]

Cross-linkable rubbery polyesters have been produced but are now no longer produced. Rubbery polyester-amides were introduced by ICI under the trade name Vulcaprene as a leathercloth material but later were used primarily as leather adhesives and as flexible coatings for rubber goods. A typical polymer may be made by condensing ethylene glycol, adipic acid and ethanolamine to a wax with a molecular weight of about 5000. [Pg.742]

A wide range of polyurethane-type products has become available in recent years for coating applications. These include simple solutions of linear polyurethanes, two-pot alkyd-isocyanate and polyether-isocyanate systems and a variety of prepolymer and adduct systems. The coatings can vary considerably in hardness and flexibility and find use mainly because of their toughness, abrasion resistance and flexibility. Uses include metal finishes in chemical plant, wood finishes for boats and sports equipment, finishes for rubber goods and rain-erosion-resistant coatings for aircraft. One type of coating is potentially competitive with PVC leathercloth. Both alkyd-di-isocyanate and adduct-diisocyanate compositions may be coated on to fabrics from solutions of controlled viscosity and solids content. Such coated fabrics are soft, flexible and, unlike PVC leathercloth, free from plasticisers. [Pg.805]

Media publicity has emphasized the introduction of robotic devices for mass production, including the automation of automotive assembly lines and the production of rubber goods, such as belts eind hose. Instrumentation for sensing mechanical motion and the subsequent control of robotic devices provides for challenging applications of numerical control strategies. [Pg.537]

SBR also finds use in conveyor belts, moulded rubber goods, shoe soles, hose and roll coverings. SBR is also available as a latex which is used in carpet backing and other applications. [Pg.97]

Resorcinol formaldehyde latex (RFL) cord dips have only a limited application within the general rubber goods industry and for adhesion to be achieved with synthetic fibres it is necessary to use the systems developed by Bayer and Degussa. These systems are based upon a combination of resorcinol, a formaldehyde donor and a hydrated silica filler (commonly called the RFK system). This system is incorporated as dry ingredients into the rubber compound and is activated by the application of heat. [Pg.139]

Polymers nowadays are not difficult to prepare because of the easy availability of the raw materials. Most of the Synthetic polymers are of recent origin but they have made an impact on our daily life. They have found extensive applications in textile fibres, rubber and rubber goods, building materials, packaging, fancy decorating articles and ion-exchange resins. [Pg.43]

Elastomeric block polymers of styrene and butadiene or iso-prene and their products of hydrogenation are finding increasing use in a variety of fields.44. Linear and radial block polymers are used extensively in injection molded rubber goods, footwear, pressure sensitive and hot melt adhesives and in mechanical rubber goods such as hose, tubing, cove base, toys, drug sundries, rubber bands, stoppers, erasers, etc. [Pg.402]

This versatility gives the synthetic polymer chemist a tool to tailor the chain of the polybutadiene to fit the desired application. It can be used to manipulate the low temperature properties important in rubber goods and tire applications. Moreover, the chemical reaction that chemists want to perform on these rubbers can be altered, depending on the reactivity of the 1,2 polybutadiene double bonds fraction versus that of 1,U polybutadiene. The work of Halasa and co-workers (21) illustrates this point. These workers hydrogenated medium vinyl polybutadiene (1,2 content varied between 60-60%... [Pg.412]
