Pillar covers

The largest area of application for ASA is the automotive sector [91,92]. Almost all automotive manufacturers use ASA for unpainted exterior parts such as mirror housings, radiator grills, cowl vent grills and pillar covers.

Typical applications for this process are bumpers or A-, B- and C-pillar covers [1, 3]. In connection with in-mold surface-decoration, cascade injection may improve the quality of the molded parts. Such moldings are not only damaged by high pressures but also there may be wrinkles at the locations of weld lines. Both problems can be avoided using cascade injection molding. But this process is not limited on decorated moldings. Often this process is also adopted to produce visible parts for the automotive industry (e.g. bumpers). 

In this process, gas (nitrogen) is injected into the molten polymer to form hollow sections inside a part. The gas can be injected via the machine nozzle or through mold nozzles. GAIM is widely employed in the automotive, consumer and furniture industry, especially for parts with thick sections. Typical products are bumpers, dashboards, pillar covers, pedals, rear guidances, automotive door panels and arm rests, handles, copier doors, housings and covers, TV and monitor cabinets, CD-ROM trays, crates, chair legs, etc. [4].

These are represented by classes D and A respectively in Fig. 4.4. The first category includes parts which could impact the driver in a collision, such as B pillar covers and the lower part of the instrument panel, and its adjacent trim panels. Unreinforced ABS and a variety of PP copolymers are commonly used for these components. The same tough, resilient materials are used for the components which need protection from the passengers feet (seat valances, kick plates), or from their golf clubs (boot liners). Door pulls arc also usually moulded from unmodified PP copolymers. Figure 4.7 shows a variety of interior panels in PP.

Polypropylene (PP) High heat resistance, superior to that of polyethylene (PE) Low cost Helps maintain a cohesive material theme throughout the interior of the vehicle through use of the same base material in different parts like pillar covers, door panels, and IP. As these parts are in constant contact with each other, use of PP enables them to withstand temperature cycles. [28]... 

The anodes can either be laid on the bottom, hung between the pillars or attached to the object to be protected. In every case they should be mounted so they can be easily exchanged. Anodes laid on the seabed are installed on concrete sleds or concrete slabs (see Fig. 16-7) so that they do not sink into the mud or become covered with sand. The current output in sand is considerably reduced due... 

Pillared clays (MELS) are aLso covered in this review. MELS have three-dimensional network structure like zeolites, and, unlike clays, which have two-dimensional layered structures, pillared cationic and anionic clays have been studied. Phthalocyanins intercalated in anionic clays have given interesting results for wastewater purification (Vaccari, 1998).

The Protein Profiling Biochip is composed of six chips assembled in a flow cell cassette device. Each chip provides 200 data points (200 pillars per chip) for a total of 1200 data points per cassette. Pillars are 50 p in diameter. The mesa on each pillar is covered with a self-assembled monolayer (20 to 25 A thickness) of biotin-derivatized PLL-g-PEG groups. A constant grafting ratio of 3.5 parts Lys to 1 part PEG is maintained with variable biotin-PEG content. sAV antibody is immobilized at 0.5 to 2 pmole/cm and Fab fragments at 4 pmole/cm. ... 

The topics contained in the book fall squarely within the realm of Combat Casualty Care, one of the pillars or mission areas for Army medical research. Specifically, the book deals with Far Forward Resuscitation, prevention and management of blood loss, wound dressing, prevention of infection, and prevention of adverse tissue responses and impaired healing. These aspects of treatment are critical to prevent death, treatment complications, and disability. They are the important aspects of early interventions in the battle area or during medical evacuation. Information covering so many aspects of this type of care are not usually found in a single source. This book will compile a large amount of important information that is current and state of the art. It will help to define the Standard of Care.
