Fillers stability

Optical properties are related to both the degree of crystallinity and the actual polymer structure. Most polymers do not possess color site units, so are colorless and transparent. But, some phenolic resins and polyacetylenes are colored, translucent, or opaque. Polymers that are transparent to visible light may be colored by the addition of colorants, and some become opaque as a result of the presence of additives such as fillers, stabilizers, moisture, and gases. 

Finally, in the preparation of gas-filled materials on the basis of polymer-oligomer compositions, oligomers which are plasticizers or lubricants of the corresponding high polymers are used. Such compositions ensure miscibility of components with blowing agents, fillers, stabilizers, etc. and subsequent foaming of polymers is usually... 

Just as in the manufacture of sheet natural rubber and the asphaltic sheet linings, the basic material as the sheet lining manufacturer receives it from the plantation (rubber) or from the refiner or importer (asphalt), the manufacturer of the synthetic lining materials will receive his synthetic elastomer, thermoplastic or other basic resin from the company that produces it-and will have to blend it with fillers, stabilizers, plasticizers, and other materials to make a suitable compound which will-as a lining—perform its function satisfactorily under the anticipated conditions, and for an economical length of time. The actual amount of the basic resinous material in the compound may be as low as 70% of the total weight. 

The dispersion stability can be increased due to thickeners added, e.g. ethoxylated urethanes, which are able to form associates with the film forming latex [201]. At the same time, the dispersion contains a certain amount of surfactants these is free surfactant present in the latex, and added surfactant to disperse pigments and fillers. Stability is achieved by varying interaction with the two dispersed phases - latex particles associated with the thickener, and pigment particles. 

In addition to the four primary components in a rubber formulation—the polymer system, fillers, stabilizer system, and vulcanization system—there are a range of secondary materials such as processing aids, resins, and coloring agents (e.g., titanium dioxide used in tire white sidewalls). These are briefly discussed to establish a guideline for the use of the materials in practical rubber formulations.
