Retailers, OEMs, and packaging suppliers are feeling strong pressures from both their supply chain and consumers to reduce all packaging and use packaging materials that are more environmentally sustainable. At the same time, pressures to manage costs, enclose products in ways that increase shelf-life, reduce tampering, confirm items are not counterfeit, and showcase products in an appealing manner continue to be important.

Elastomeric components are now widely produced from thermoplastic elastomers, TPEs. Selecting the better candidates and grades to work on for optimizing a part application is complicated by the wide range of TPEs now commercially available. New TPE grades are being introduced on a regular basis and understanding the primary issues that drive the material selection process for TPEs will facilitate the process of material selection.

Newly emerging clarifying agents for polypropylene (PP) and blown-film polyethylene (PE) do more than make these polymers more transparent. They also offer other a host of other improvements, including greater strength, fewer taste and odor problems, lower effective usage concentrations, and reduced cycle times in processing. As a result, these multifunctional clarifiers promise to extend the performance range of PP and PE, making them suitable for markets that were previously closed to them.

The rising cost of plastic resins, driven by soaring crude oil prices, is arousing interest in resin formulations containing high levels of fillers, particularly relatively low-cost minerals and glass. Not only do these fillers bring down the cost of fabricated plastic products, they often provide other improvements. These gains include greater output in blow molding or extrusion, higher impact strength and greater structural integrity of molded goods. Recently, plastics additive suppliers and equipment manufacturers have come up with new technologies that enable processors to maximize levels of fillers in their resin formulations, and minimize some of the problems that can result from high filler levels.

HiTUS, a cutting edge plasma thin film deposition is a major evolution from the traditional magnetron technology widely used in industrial and research circles. The essential factor of this leading edge thin film deposition coating technology is a remotely generated high intensity plasma that gives a number of important benefits that are unavailable from magnetron, ion beam, thermal evaporation and chemical vapour deposition coating systems. The HiTUS process delivers very high quality thin film materials with near ideal physical properties, very low stress and excellent adhesion-whether on metal, glass or plastic substrates.

Smart/interactive textiles (SMITs) are a new type of textile technology. Conductive polymers are playing an important role as conductive fibers in the development of these smart textiles for a broad range of applications. In the future, cloth or fabrics will not only protect the wearer and the environment, but also will have intelligent built-in features, such as multifunctional sensors or computing devices.

Fillers for plastics are basically divided into inactive (or extender) fillers and active (or functional) fillers. Fillers are very widely used in the plastics industry, and their growth rates currently exceed those of the resins themselves. They are used in all three major categories of polymers (thermoplastics, thermosets and rubbers). Fillers are essential components of many polymeric products; the fillers market is both complex and valuable (2.3 billion Euros in Europe in 2008).

Natural fibers are enjoying a comeback in high-tech development. The related research has experienced an explosion of interest, particularly with regard to natural fiber's comparable properties to glass fibers within composites materials. Above all, the automotive industry is interested because cars have been required to be partially decomposable or recyclable since 2006. The main area of increased usage is in interior applications, because the need is the greatest here. A DEFRA report from 2002 projected the growth rates for bio-fibers in automotive components at 54% per year.

Thermoplastic elastomers are remarkably versatile, either used on their own or overmoulded to provide tactile or functional features on components moulded from other polymers. Material properties can vary considerably from one grade to the next, with the difference being down to the chemistry and the presence of filler materials or additives.

When talking about bioplastics, most people immediately think of biobased and/or biodegradable packaging. This is quite understandable, as most examples currently reported in the press and available in the market are of packaging applications. However, other industries are also carefully evaluating bioplastics, or even using them already.

As the number of environmentally conscious consumers continue to grow into a transformative global force, the market demand for biopolymers also continues to increase.

The global healthcare industry is starting to seriously embrace sustainable management and greener purchasing policies. Health professionals and healthcare administrators are rapidly realizing that developing and running a green facility does not have to be costly and that in many cases there are real operational savings to be made.

A driving economic reality of the wood-plastics composites (WPC) business is that the end product costs more than natural wood. Energy costs are a significant part of the equation. WPC compensates for its higher price by offering durability and minimum maintenance requirements, along with ease of installation and attractive appearance.

It may be possible to make things invisible by putting a thin layer of a specially patterned material in the way. Appropriately made, these materials with repeated three dimensional structures less than the wavelength of the radiation used will break the traditional laws of optics and magnetics because they employ quantum effects.

In short, although sustainability is mentioned in almost every new article for the plastics industry and lip service is paid to it by many of the major players, few customers are demanding it. It is almost as if the general public know it is important, as do businesses, but they haven't quite worked out how to incorporate it into their plans yet.

Interesting problems arise when sedan cars are reengineered as roadsters or convertibles. Removing the roof to create an open cockpit typically lowers a vehicle's torsional rigidity by at least half, leading to concurrent losses in handling "crispness" and ride. The challenge - and opportunity - is how to add stiffness back without paying too high a weight or cost penalty.

A newly published study by the Automotive Composites Alliance (ACA), a division of the American Composites Manufacturers Association (ACMA), says that composites make better sense for hybrid-electric vehicles than steel or aluminum. This is because no competitive material/process combination offers more possibilities to reduce weight, lower tooling investment and part costs, and provide opportunities for parts consolidation and reduction or elimination of secondary-finishing operations.

As the range of materials available for use with SLS and their properties are further developed, more applications are emerging, some of which are quite unusual.

It is widely known and published that modern sterilization techniques used in the healthcare industry can have a detrimental effect on thermoplastic polymers. In particular,gamma sterilization, which is the most common ionization method, can cause substantial changes to occur in polymeric materials. Polymer chain scission and cross linking can both occur, altering the physical properties and appearance of materials and ultimately affecting the functionality of a device utilizing these materials. RTP Company’s TPE (Thermoplastic Elastomer) Division has initiated a series of projects to measure the effect different sterilization methods have on RTP Company’s standard TPE products used in medical devices. This paper discusses the effect gamma sterilization has on these various TPE compounds produced by RTP Company for the healthcare industry.

Direct part marking enables tracking a product from the time of manufacturing until the end of its useful life.Direct part marking containing unique identification information necessitates digital process technology such as inkjet, dot peen, and laser marking.

A little research reveals that ultrasonic plastic welding machines can be purchased in a variety of frequencies, including 15, 20, 27, 30, 35, 40, 50, 60, or 70 KHz. As if this doesn't create enough confusion, even more frequencies most likely are available. If two potential suppliers recommend different frequencies, which one is providing the best information? If an ultrasonic welder of one frequency already is in place, is there a need to buy another of a different frequency? Does it really matter?

Automotive safety restraint system components increasingly use flexible styrenic and olefinic TPEs. With continued evolution in automotive interior design and performance requirements, demands on material technology are concomitantly rising. A growing trend towards molded in color solutions with low gloss aesthetics require TPE materials with very low gloss, improved scratch resistance, and low temperature ductility. Innovations utilizing Teknor Apex's compounding technology have enabled the development of low gloss styrenic elastomers for airbag door applications that provide an optimized combination of low temperature performance, surface aesthetics (low gloss and improved scratch resistance), and ease of processing. This paper highlights the salient features of these new compounds and the effect of injection molding condition on the gloss at the surface of the cover.

White-light emitting ultra-small CdSe nanocrystals present exciting possibilities in the area of solid-state lighting technology. In this work, thirteen dissimilar polymers were examined as potential encapsulants for these single-sized nanocrystals. Films of the encased nanocrystals were characterized in terms of nanocrystal aggregation and changes to the nanocrystals' natural emission. The Hildebrand and Hansen solubility parameters of each encapsulant were found to be correlated to the quality of nanocrystal encapsulation achieved. Encapsulants with cyclosiloxane or bisphenol-A type epoxy structures caused extensive aggregation of the nanocrystals at low loading levels (<0.5% w/w) due to the solubility difference between the polymer structure and the nanocrystals' ligands. Of the encapsulants tested, the most robust, color stable, and homogenous encapsulation was obtained using a biphenylperfluorocyclobutyl polymer. In this polymer, nanocrystal loading levels up to 18% w/w were achieved. White-light emitting CdSe nanocrystals encapsulated in the biphenylperfluorocyclobutyl polymer were coated on various UV-LEDs creating a white light source with chromaticity coordinates of (0.324, 0.322) and a high color-rendering index of 93.

In addition, the PCM application increases the thermal comfort inside the passenger compartment, and could delay the aging process of the cover material of the instrument panel. Applied to the seats, the PCM improves their thermal comfort substantially, especially on hot summer days. The PCM-film application in the discussed components is durable, maintenance free and does not require the use of any external energy supply.
Energy can be saved and the thermal comfort inside the passenger compartment can be enhanced by the application of textile composites with thermoregulating properties. The thermo-regulating properties are provided by the application of phase change material (PCM) - a highly productive thermal storage mean. In order to create the textile composites with thermo-regulating properties the PCM is contained in a polymeric film that is laminated to a textile carrier. A study has indicated that the application of the developed composites is especially beneficial in car seats, headliners and instrument panels. In the paper, specific solutions for the application of the textile composites in car seats, headliners and instrument panels will be introduced and test results, received in rigorous field tests, will be discussed.
