Additives fillers

Commercially produced elastic materials have a number of additives. Fillers, such as carbon black, increase tensile strength and elasticity by forming weak cross links between chains. This also makes a material stilfer and increases toughness. Plasticizers may be added to soften the material. Determining the effect of additives is generally done experimentally, although mesoscale methods have the potential to simulate this. [Pg.313]

Model plasters are manufactured from select finishing plasters with special emphasis on a clean, white color. Setting-time control agents, setting-expansion control additives, fillers, and pigments may be added. [Pg.476]

Each of these additives plays an important role in either the processing or service life of the finished goods. In addition, fillers and pigments are two larger scale additives that play an important role in product economics and aesthetics. [Pg.318]

Many different additives, fillers, and/or reinforcements are used in plastic materials. The weight of the compounds change according to the amount included. Figure 5-3 provides a guide to determining their specific gravities. [Pg.305]

The term s plastic, polymer, resin, elastomer, and reinforced plastic (RP) are some-what synonymous. However, polymer and resin usually denote the basic material. Whereas plastic pertains to polymers or resins containing additives, fillers, and/or reinforcements. Recognize that practically all materials worldwide contain some type of additive or ingredient. An elastomer is a rubberlike material (natural or synthetic). Reinforced plastics (also called composites although to be more accurate called plastic composites) are plastics with reinforcing additives, such as fibers and whiskers, added principally to increase the product s mechanical properties. [Pg.338]

In addition to the broad categories of TPs and TSs, TPs can be further classified in terms of their structure, as either crystalline, amorphous, or liquid crystalline. Other classes (terms) include elastomers, copolymers, compounds, commodity resins, engineering plastics, or neat plastics. Additives, fillers, and reinforcements are other classifications that relate directly to plastics properties and performance. [Pg.340]

Identifies a plastics with Nothing Else Added To. It is a true virgin polymer since it does not contain additives, fillers, etc. These are very rarely used. [Pg.363]

Even though equipment operations have understandable but controllable variables that influence processing, the usual most uncontrollable variable in the process can be the plastic material. The degree of properly compounding or blending by the plastic manufacturer, converter, or in-house by the fabricator is important. Most additives, fillers, and/or reinforcements when not properly compounded will significantly influence processability and fabricated product performances. [Pg.368]

For applications having only moderate thermal requirements, thermal decomposition may not be an important consideration. However, if the product requires dimensional stability at high temperatures, it is possible that its service temperature or processing temperature may approach its temperature of decomposition (Tj) (Table 7-12). A plastic s decomposition temperature is largely determined by the elements and their bonding within the molecular structures as well as the characteristics of additives, fillers, and reinforcements that may be in them. [Pg.399]

It has been well established that wear resistance of filled rubber is essentially determined by filler loading, filler morphology, and polymer-filler interaction. For fillers having similar morphologies, an increase in polymer-filler interaction, either through enhancement of physical adsorption of polymer chains on the filler surface, or via creation of chemical linkages between filler and polymer, is crucial to the enhancement of wear resistance. In addition, filler dispersion is also essential as it is directly related to the contact area of polymer with filler, hence polymer-filler interaction. [Pg.945]

Over the last 25 years, many commercial products have been made by melt blending PBT with other resins. Blending is most commonly carried out by extruding the PBT resin with a second resin component. Other additives, fillers, or reinforcements may be added to the blends as well. [Pg.307]

In addition, fillers can be used for both cost reduction and property modification. Table 21.3 presents some examples of typical fillers and their effects on the unsaturated polyester resin formulation properties. [Pg.707]

The property sets of raw PVCs as-polymerized are generally unsuitable for the range of intended applications. It is essential to upgrade and customize the raw polymers by compounding to satisfy the requirements of customers and applications. Numerous additives, fillers, plasticizers, stabilizers etc. are used, allowing the manufacture of a variety of parts and goods from a very rigid to a very soft character. [Pg.309]

Lastly PVC/PVAc are the most-used copolymers for some speciality application niches. They are appreciated for their lower melt viscosities, higher tolerance to additive fillers, and better cold-draw properties than homopolymers. [Pg.310]

One would expect that addition filler of similar structure would reinforce the hard segments. It was found that the addition of thermoplastic polyolefins of high melting point did improve the physical properties. [Pg.413]

The high-temperature resins described above provide the main elements in the adhesive formulator s recipe. However, there are also additives, fillers, etc., that can further enhance the thermal properties of more conventional epoxy adhesives. These additional components improve thermal resistance by providing oxidation resistance, toughening, and control of bond line stress. [Pg.300]

There are different types of plastics that are usually identified by their composition and/or performance. As an example there are virgin plastics. They are plastic materials that have not been subjected to any fabricating process. NEAT polymers identify plastics with Nothing Else Added To. They are true virgin polymers since they do not contain additives, fillers, etc. They are very rarely used. Plastic materials to be processed are in the form of pellets, granules, flakes, powders, flocks, liquids, etc. Of the 35,000 types available worldwide there are about 200 basic types or families that are commercially recognized with less than 20 that are popularly used. Examples of these plastics are shown in Table 1.1. [Pg.4]

The materials being reviewed in this book, as in the industry, are identified by different terms such as polymer, plastic, resin, elastomer, reinforced plastic (RP), and composite unreinforced or reinforced plastic. They are somewhat synonymous. Polymers, the basic ingredients in plastics, can be defined as high molecular weight organic chemical compounds, synthetic or natural substances consisting of molecules. Practically all of these polymers are compounded with other products (additives, fillers, reinforcements, etc.) to provide many different properties and/or processing capabilities. Thus plastics is the correct technical term to use except in very few applications where only the polymer is used to fabricate products. [Pg.9]

Converting polymers to almost 35,000 plastics includes mechanical mixing/blending one or more polymers with additives, fillers, and/or reinforcement. They do not normally depend on chemical bonds, but do often require special compatibilizers. Mechanical compounding is extensively used (Chapter 5). [Pg.15]

In the past engineering TPs have replaced metal in numerous products in many industries by providing improvements in thermal properties.146 The ability to prepare and compound material properties through the choice of plastics with additives, fillers and reinforcements, has allowed the development of the flexibility inherent in TPs to meet the performance requirements required in these different applications. [Pg.27]

The twin-screw extruder may have parallel or conical screws, and these screws may rotate in the same direction (co-rotating) or in opposite directions (contra-rotating). Extruders with more than two screws are known as the multiple-screw extruder. These extruders are normally used when mixing and homogenization of the melt is very important, in particular where additives, fillers, and/or reinforcements are to be included in the plastic. [Pg.230]
