Novel plastics

On his return home in 1911, Honda was appointed professor of physies at the new Tohoku Imperial University in Sendai, in the north of Japan this institution had been established only in 1906, when the finance minister twisted the arm of an industrialist who had made himself unpopular because of pollution eaused by his copper mines and extracted the necessary funds to build the new university. A provisional institute of physical and chemical research was initiated in 1916, divided into a part devoted to novel plastics and another to metals. This proved to be Honda s lifetime domain he assembled a lively team of young physicists and chemists. In the same year, Honda invented a high-cobalt steel also containing tungsten and chromium, which had by far the highest coercivity of any permanent-magnet material then known. He called it KS steel, for K. Sumitomo, one of his sponsors, and it made Honda famous. 

Pol Tner Nanocomposites are novel plastic compounds with a filler having dimensions between 1 and 100 nm. They have attracted much attention in the past because nanocomposites exhibit markedly improved properties like stiffness, thermal flammability, improved barrier properties and others compared to the unfilled matrices [3], Among all potential fillers, those based on easily available clay and layered silicates have been more widely investigated for some time now. 

Amine-resin thermosetting materials (plastics) are manufactured in all industrially developed countries. Aminoplasts are still one of the most common types of polymeric materials although production of novel plastics is rapidly growing. 

In a way, conducting polymers are at the same stage of development as their insulating brothers were some 50 years ago. Regardless of the practical application that are eventually developed for them, they will certainly be challenge to researchers with new and unexpected phenomena. Only time will tell whether the impact of these novel plastics will be as large as their insulating relatives or more. 

Butanediol was also used as an intermediate in the production of polyurethanes. These novel plastics had been discovered by Otto Bayer, Reppe s counterpart at Leverkusen, in 1937.52 formed by the condensation of di-isocyanates (derived from... 

A novel flame retarding plasticizer is based on polyetltylene stibnite phosphate esters. It contains all essential elements present in compounds having flame retarding properties, such as Sb, P, and halogens. The plasticizer has the advantage of a uniform distribution of antimony oxide which is formed in situ but it is not sufficiently stable at elevated temperamres and to hydrolysis. " Low smoke generation was obtained with a novel plasticizer based on pentaerythritol. ...

Responsible use of non-renewable resources is one of the three emphasis areas in the sustainable growth (Chapter 2). Any technologies that help conserve fossil fuel reserves help achieve that goal. Using renewable bioresources to make plastics, especially types of plastics used in high volume, is therefore a sustainable move by the industry (Philp et al., 2013 Reddy et al., 2013). Biomass raw materials can yield the same basic chemical intermediates that are derived from fossil fuel raw materials, making bio-based synthesis of conventional and novel plastics a possibility. The option is particularly attractive where the embodied energy as well as the carbon emissions associated with manufacture of the bio-derived variety is at or below that of conventional plastic material.

As consumer products become smaller and offer more services to the user, one frequent consequence is that they contain increasing numbers of physically smaller components. A typical example of this trend is the hearing aid where the emphasis is on providing a more powerful and efficient device which will improve the wearer s quality of life. The Acuris P hearing aid from Siemens incorporates a moulded interconnect device (MID) made from Ticona s Vectra E820i LDS liquid crystal polymer (TCP). This novel plastic permits complex, fine-line circuit patterns to be laser-etched and then plated. The MID itself, whose function is to connect the microphone module to other electronic components in the unit, is approximately 3 mm wide and 25 mm long. 

Cell construction cost reduction involves development of novel plastic monoblock housings reduction of piece parts through monoblock construction, low cost plastic materials where possible, shared terminals and vents and standardized sizes. 

Metallocene-based polyolefin alloys, blends and compounds, an emerging class of novel plastic products, offer an unique combination of performance properties. In polymer blending and/or alloying, often dissimilar polymers are physically mixed (com-patibilized) and/or chemically reacted (reactive extrusion processing). 

Microcapsules are also used in novel plastics that can automatically repair damage known as self-healing materials. 

Due to several sources of credible information, it became highly doubtful that a novel plastic was being produced. Instead, it was suspected that the Sample A product was being purchased and repackaged as being representative of pilot scale quantities of Sample B. If Sample A and Sample B were produced in different facilities using different reaction parameters then some differences between the two samples would result. Polymer Solutions Inc. was asked to compare the chemical compositions and key chemical and physical properties of the two polyacetal resins to determine if Sample B was counterfeit. It was concluded that there were no differences between Sample A and Sample B so Sample B was essentially a counterfeit plastic resin.
