Automotive airbag

A crosslinkable silicone rubber coating composition, (I), was prepared by Azechi [1] and used in preparing automotive airbags. 

FUm Applications Anti-corrosive linings, non-stick roll covers, pharmaceutical cap liners, microphone electrical membranes, photovoltaic cell glazing, antigraffiti coverings, erasable surface coverings, automotive airbag systems, fuel hose permeation barriers, hot melt adhesives, and many others.

Our goal in this chapter is to understand how to determine reaction rates and to consider the factors that control these rates. What factors determine how rapidly food spoils, for instance How does one design an automotive airbag that fills extremely rapidly following a car crash What determines the rate at which steel rusts How can we remove hazardous pollutants in automobile exhaust before the exhaust leaves the tailpipe Although we will not address these specific questions, we will see that the rates of all chemical reactions are subject to the same principles. 

A word of caution Alkyl azides are explosive, and low-molecular-weight alkyl azides should not be isolated but should be kept in solution. Sodium azide is used in automotive airbags. 

One of the first demonstrations of diamond s usefulness in electroanalysis was the oxidative detection of azide anion in aqueous media [29,30,37]. Sodium azide has been widely used commercially and, in the past, as an inflator for automotive airbags. Azide anion is highly toxic and presents a... 

Poly(tetramethylenediamine-co-adipic acid), nylon-4,6 [24936-71-8], polymer introduced as Stanyl by Dutch State Mines is spim into a high-temperature-resistant, high-tenacity filament yam, Stanylenka 460 HRST, by Akzo Nobel Faser AG in Wuppertal, Germany. Stanylenka is intended for industrial applications including tire cord and automotive airbags because of its enhanced heat capacity, improved chemical resistance, better dimentional stability, and higher modulus than nylon-6,6 (176). The fiber melts at 285°C and has a density of 1.18 g/cm . 

Sodium azide is reactive compound that is widely used commercially as a propellant in automotive airbags. The azide anion is highly toxic and can present health hazards at high levels, in the form of headaches, cytochrome oxidase inhibition and vasodilation. Usage of azide in airbags increases contamination in... 

RCF is sold in a variety of forms, such as loose fiber, blanket, boards, modules, cloth, cements, putties, paper, coatings, felt, vacuum-formed shapes, rope, braid, tape, and textiles. The products are principally used for industrial appHcations as insulation in furnaces, heaters, kiln linings, furnace doors, metal launders, tank car insulation, and other uses up to 1400°C. RCF-consuming industries include ferrous and nonferrous metals, petrochemical, ceramic, glass, chemical, fertiH2er, transportation, constmction, and power generation/incineration. Some newer uses include commercial fire protection and appHcations in aerospace, eg, heat shields and automotive, eg, catalytic converters, metal reinforcement, heat shields, brake pads, and airbags. 

The latest development are micromechanical sensors. Their development began with the large-scale introduction of silicon micromachined pressure sensors to the automotive industry in the nineties, which entailed a massive price reduction. Then acceleration sensors for airbag firing, yaw rate sensors and more were introduced. Many devices are still being discovered. The next step is product evolution, with introduction times between a few years and over a decade, as shown in Tab. 2.2. Once customers in the industry have accepted a product, investment in large-scale production can go ahead. It helps to find more applications for the product The time scale for the product evolution process varies from about five... 

In the initial stages, the end use of n-Al was largely dominated by defense-related applications. Small caliber primers for defense munitions, additives for solid and hybrid rocket propellants, enhanced lethality explosives and pyrotechnics and thermite-based weapons are some typical military applications of n-Al powder. The use of n-Al powder has also been reported for some civil applications such as fireworks, automotive inflators and airbag initiators as well as drilling and oil exploration. 

In recent years, the automotive sensor market in Europe has grown strongly and is now of equal importance to the US market Emission-related legislation has now reached comparable standards as in the US. In addition, the European consumer has demanded safety-related features, many of which, such as ABS and the airbag (including side airbags), are now considered standard equipment...

In terms of security, they are often irreplaceable. This is the case of the airbag in automobiles. Without polymers, how can we achieve this protective ball With a pig s bladder But then, how to integrate onto this skin the very sophisticated technology which allows the liberating explosion of the ball without injuring the driver There is no solution outside the plasticity of polymers. So, today, 50% of plastics applications in the automotive sector are no longer substitutable. 

The automotive industry has found several other applications where the additional cost of specialty may be beneficial. These areas are manifolds and tailpipes, catalytic converters, high-temperature fasteners, exhaust valves, airbag inflators, and other critical electrical components. The future use of these materials will depend on the benefits found in service and the changes in automotive technology that affect the corrosion conditions encountered by automobiles.
