Rubber reinforcing agents

Use Glass, ceramics, iron-free aluminum and aluminum salts, manufacture of activated alumina, base for organic lakes, flame retardants, mattress batting. Finely divided form (0.1-0.6 microns) used for rubber reinforcing agent, paper coating, filler, cosmetics. 

Use To encapsulate pesticides the coating, though insoluble, is permeable to water, thus slowly releasing the pesticide. Rubber-reinforcing agent. 

CAS 112945-52-5 EINECS/ELINCS 231-545-4 Uses Reinforcing agent, fiiier for HTV siiicone rubber reinforcing agent, fiiier, thickener for RTV-1 siiicone rubber and poiysuifides free-fiow agent for moisture-sensitive substances antisettiing agent for paints and lacquers... 

Rubber-GradG Carbon Blacks. Carbon black is a major component in the manufacture of rubber products, with a consumption second only to rubber itself It is by far the most active rubber-reinforcing agent owing to its unique ability to enhance the physical properties of rubbers. Table 7 lists the principal rubber grades by their N-number classification, general rubber properties, and typical uses. 

Polysaccharides such as starch and cellulose have been used as reinforcing agents in natural rubber. Both solution blending and dry mixing methods have been employed for the development of biocomposites and the performance compared with the composites obtained using carbon black. Dry mixing method is more economically viable and environment friendly.

An isomeric derivative of natural rubber produced by a variety of chemical treatments. The products are resinous and find application as reinforcing agents in natural rubber compounds (particularly in shoe soles) and as rubber-to-metal adhesives. 

An activator in rubber compounds containing organic accelerators. In polychloroprene, zinc oxide is considered to be the accelerator rather than the activator. The use of zinc oxide as a reinforcing agent and as a white colouring agent is obsolescent. Zinc oxide is manufactured by either the French (or indirect) process or by the American (or direct) process. It can be used as a filler to impart high thermal conductivity. 

Although, because of its cost, titanium dioxide is usually only used as a whitening agent for rubber compounds, it is in fact a reinforcing agent comparable on a volume basis with the reinforcement found with zinc oxide. 

Uses. In the rubber, plastic, printing, and paint industries as a reinforcing agent and a pigment...
