  • Plasticizers are used to increase the process-ability, flexibility, and durability of the material, and of course to reduce the cost in many cases. This edition covers introduction and applications of various types of plasticizers including those based on non-toxic and highly effective pyrrolidones, and a new source of Collagen based bio-plasticizers that can be obtained from discarded materials from a natural source; Jumbo Squid (Dosidicus gigas).

  • Number of the equipments used in everyday life remarkably increased after the invention of synthetic polymers, especially of styrene-butadiene rubber in 1930 and of PVC in 1936, and thanks to fast-developing polymer technologies. Polymers are light, cheap and ductile inert materials, which have good mechanical and thermal properties, suitable to use for various purposes and are highly resistant to corrosion. Thanks to such properties, they play an essential and ubiquitous role in many industrial fields.

  • Example Applications Contactless Smart Cards The first plastic cards appeared in the USA as early as the beginning of the 1950s, when cheap PVC replaced cardboard. In the years that followed, plastic credit cards became widespread. Incidentally, the first credit card was issued by Diners Club in 1950. The rapid development of semiconductor technology made it possible to integrate data memory and protective logic onto a single silicon chip in the 1970s.

  • At the open burning sites, some metals were present at concentrations over one hundred times typical background levels for soils, including lead, a highly toxic metal. High levels of other toxic metals, including cadmium and antimony, were also present. Numerous classes of organic chemicals were also present in one or more of the samples, including many halogenated (chlorinated or brominated) chemicals. Many of the compounds identified are intentionally used in electronic devices.

  • Phthalates are used to make plastics like polyvinyl chloride (PVC) more flexible or resilient and also may be found in solvents. They are used in hundreds of products, including vinyl flooring, adhesives, detergents, lubricating oils, automotive plastics, plastic clothing such as raincoats, and personal care products such as soap, shampoo, hair spray, and nail polish. Before 1999, phthalates were used in pacifiers, soft rattles, and teethers (CDC 2005).

  • PVC tubing, creating the effect of diaphanous surfaces of flowing plastic hair that create shade and accommodate program. The sensuous lines are a constructive solution that cumulatively define the larger surfaces and representationally echo the digital method that made them. That is, the lines define the physical surface in the same way that embedded surface curves, or isoparms, make up a digitally ruled or lofted, one. Massie's method coordinates well with conventional building materials.
