Although most interest in plastics focuses on their standard physical properties, the sensory external qualities of POs help these relatively low-strength materials take applications from more expensive, rigid engineering resins. Other chapters have touched on sensory characteristics as well (e.g., colorants and clarifiers), but this chapter will focus on additional issues of most current interest in the industry, including ...

In comparison with other additives used in packaging materials, plasticizers focus attention as they need to be used in high amounts in glassy polymers, up to 50 wt% in PVC and up to 30 wt% in PLA to reach the expected mechanical properties. 

Yasushi Miyano - received his BS (1964), MS (1966) and PhD (1969) degrees from Keio University in Japan. After graduation, he was employed at Hitachi Research Laboratory, Hitachi Ltd., until 1977. He is a Professor in Kanazawa Institute of Technology since 1977, and also the Director of the Materials System Research Laboratory at this school. He is investigating the durability of advanced fiber-reinforced plastics, focusing on the residual stress analysis in polymers and the experimental viscoelastic analysis. 

The air-coupled ultrasonic probes are essentially built up by the piezo-composite plate and a front side matching layer, made of air bubbles filled plastic materials. By using a thermoplastic material as matrix material of the composite, the transducer can easily be shaped by heating up, forming and cooling down to realize focusing transducers. Because of the low... 

Light-focusing plastic rods and other optical devices with graduated refractive indexes may use DADC and other monomers (29). Preparation and properties of plastic lenses from CR-39 are reviewed in reference 30. 

Because of low prices and steadily rising performance on the part of technical and standard plastics, the application of natural fibers came to a near halt. The current critical discussion about preservation of natural resources and recycling led to a reflection about natural materials, the focus centuring on regrowing raw materials [2]. 

With plastics to a greater extent than other materials, an opportunity exists to optimize product design by focusing on material composition and orientation to structural member geometry when required. The type of designer to produce a product depends on the product requirements. As an example in most cases an engineering designer is not needed... 

RAPRA free Internet search engine. The number of plastic-related web sites is increasing exponentially, yet searching for relevant information is often laborious and costly. During 1999 RAPRA Technology Ltd., the UK-based plastics and rubber consultancy, launched what is believed to be the first free Internet search engine focused exclusively in the plastics industry. It is called Polymer Search on the Internet (PSI). It is accessible at www.polymersearch.com. Companies involved in any plastic-related activity are invited to submit their web-site address for free inclusion on PSI. RAPRA Technology s USA office is in Charlotte, NC (tel. 704-571-4005). 

Fungal and bacterial deterioration are identified as microbiological and have always caused problems to materials. Fungal attack on plastics has received a great deal of attention beginning with the early days of World War II, when the tropical theaters served to focus attention on the overall problem of materials deterioration. 

Plastics offer the opportunity to optimize RP design by focusing on material composition in conjunction with reinforcement orientation, as well as product structural geometry. This interrelation affects processing methods, product performances, and costs. This action also gives the designer great flexibility and provides freedom not possible with... 

Plastics product design engineering handbook , Sidney Levy and T. Harry DuBois Van Nostrand Reinhold, (Kluwer Academic Publishers) (1977) ASIN 0412005115. A classic design course converted to book format that provides a very good introduction to a multitude of basic design features and environments focused on specific examples and end use application areas.
