Figure 4.8 ((a), (b), (c), and (d)) displays, in a simplified manner, the alteration of the basic properties of homopolymer (H-PP) when modified with other comonomers (co-PP), with elastomer (impact) or with an inorganic filler mineral, talc, short or long glass fibres (SGF or LGF). 

Calcium carbonate is the most widely used filler mineral in the world. Its success is mainly due to its availability and also its suitability for a large range of applications. 

In response to concerns about halogenated FRs, resin users have inaeased their use of mineral-based FRs, especially magnesium (di-)hydroxide (Mg(0H)2 MDH) and less-costly, more widely used aluminum trihydrate (or aluminum hydroxide Al(OH)3 ATH). These can be used alone, together synergistically, or in combination with other fillers. Mineral FRs are used in PE and PP for wire and cable, and in flooring, roof tiles, conduits, sheets, film, and wall coverings, along with other construction and nonconstruction applications. 

Nonetheless, impact strength often must be saaificed by additions of low-cost fillers. Mineral fillers usually tend to stiffen PO compounds but also lower their toughness. Thus, increasing these filler loadings without considering effects on impact, tear, or pimcture resistance could be a redpe for failed resin produrts. 

Flexibility in operation because it is designed for more than one type of additive component it can easily be converted to process fillers or fibres or chopped scrap foam. Its range of application includes continuous reinforcing fibres, natural fillers (mineral or organic), pulverised plastics, etc.

This chapter focuses on the non-linear viscoelastic behavior of rubber composites and nanocomposites. Here, we have discussed about the effect of individual fillers (mineral fillers, nanotubes, carbon nanofillers, fibrous nanofiUers, biofillers, special structured fillers viz. nanorods, nanowires, nanoflowers etc.) on the linear/ nonlinear viscoelastic behavior of rubber composites. Moreover, as this chapter is more concerned on the non-linear viscoelastic behavior, we have also discussed the effect of hybrid fillers on the nonUnear viscoelastic behavior of rubber composites in more detail. 

Fillers are defined as additives in solid form that differ from the polymer/rubber matrix with respect to their composition and structure. A mineral filler is defined as a finely pulverized inert mineral or rock that is included in a manufactured product (e.g. paper, rubber, and plastics) to impart certain useful properties, such as hardness, smoothness, or strength etc (http //www.mindat.org/glossary/ mineral filler). Mineral particulate fillers are used in rubber/polymer composites to reduce the cost of the final product and to add some mineral property with the host (rubber/polymer) matrix, that is, to improve the properties of the matrix [19-22]. Common mineral fillers include asbestos, kaolin, talc, mica, wollastonite, and calcium carbonate etc (http //www.mmdat.org/glossary/mmeral filler) [19]. 

Mineral Filler - Mineral fillers are a large subclass of inorganic fillers comprised of ground rocks or natural or refined minerals. Some fillers, so-called commodity minerals, are relatively inexpensive and are used mostly as extenders. A good example of these is ground limestone. Other fillers, so-called specialty minerals, are usually reinforcing fillers. These are inherently small particle size fillers, such as talc, and surface chemically modified fillers. See also Organic Filler. 

Talc has been the second mineral of choice to fill polypropylene. Such applications have usually been automotive and industrial. Talc is a general purpose filler mineral and is highly compatible with polyolefins. It is widely used to increase stiffness and heat resistance in polypropylene automobile trim parts that do not require high reinforcement. 

If filled polymers are used, they are usually first extrusion compounded into pellets which are then pulverized, often cryogenically. Blends of powdered polymer and filler mineral do not work well since there is no means to force the wetting of the filler powder by the plastic as it melts.
