Organic or Inorganic Fillers

Simple additions of organic or inorganic fillers and components... 

Traditionally acrylie polymers are used in the form of dyes, lacquers, enamels [1,2]. But properties of the filled aerylic polymers are studied insufficiently, though filled with organic or inorganic fillers polymer compositions that have various chemical nature and strueture, are being widely employed [3]. 

Being based on the above discussed results we can estimate that durability dependence on content of each type of the fillers (organic or inorganic) is linear ... 

In some applications, it is useful to incorporate nonplastic substances into a plastic object, to reduce its cost or improve its performance in some way. Fillers are typically used to lower the cost of the plastic, and generally consist of minerals of some kind. Reinforcements are often more expensive, per unit mass or volume, than the plastics, but provide improvement in properties such as strength and/or rigidity. They usually consist of either organic or inorganic fibers. Use of fillers and reinforcements is less common in packaging applications than in uses such as automotive components or housewares, but is sometimes significant. In addition, these additives are more commonly used with thermoset polymers than with thermoplastics. 

POCs are composed of two or more phases. The matrix is the polyolefin with a continuous phase that surrounds the other phases. The filler could be a reinforcement material for the entire composite. The properties of the polyolefin composite are dependent upon the filler type (organic or inorganic), geometry (fiber, flake, particulate, or sphere), the type of matrix, and the size of filler (micro or nano). Figure 6.1 depicts a simple schematic classification of a polyolefin composite [28]. 

Therefore, these materials must be high in strength, low in wear and abrasion, and resistant to moisture and hydraulic fluids. These materials contain several components. Among them are phenolic resins, rubber, organic and inorganic fillers, metals, and fibers, such as mineral-, carbon-, aramid- or metal fibers. Phenolics function as binders in the friction materials. The phenolics are modified in different ways to increase flexibility and abrasion resistance as well as to improve the... 

Plastics are generally organic polymers of high molecular mass. They are usually synthetic and derived from petrochemicals. Also they are malleable and can be molded into solid objects of various shapes. Most plastics contain other organic or inorganic compounds that are blended in. These include fillers which improve performance and may reduce production costs. One such additive might be a fire retardant to lower the flammability of the material. Another could be a colorant to enhance its appearance. Figure 3 displays a plastic vase [13]. 

Fillers. Fillers (qv) are incorporated in epoxy formulations to enhance or obtain specific desired properties in a system. The tsq)e and amoimt of filler used are determined by the specific properties desired. Fillers can also reduce the cost of epoxy formulations. Inert commercial fillers (qv) can be organic or inorganic, and spheroidal, granular, fibrous, or lamellar in shape. The properties of commercial fillers are given in Table 21, and some effects on epoxy resins are shown in Tables 22 and 23. Some formulations contain up to 90 wt% fillers. For certain applications, fillers can have significant effects on thermoset morphology, adhesion, and the resulting performance.
