Selection automotive applications

Rubber Blends For Automotive Applications. The ionomers from Exxpro elastomer can be blended with other elastomers such as Neoprene(CR), Nitrile(NBR), and Acrylics(VAMAC) for selected automotive applications, e.g., hoses, air springs, and belts.

A modified concept for the generation of partially crosslinked expanded PP films and sheets for use in automotive applications is presented. An optimised formulation window for the organosilane crosslinking of selected PP copolymers is described in detail. 5 refs. 

This book (Volume 2) presents more than 800 up-to-date advanced cleaning product formulations for household, industrial and automotive applications. It is the result of information received from numerous industrial companies and other organizations. The data represent selections made at no cost to, nor influence from, the makers or distributors of these materials. Only the most recent formulas have been included. All formulations are completely different than those contained in Volume t, which was published in 1989.

An important aspect related to air supply sub-system for the attainment of optimal FCS operation is the selection of a compressor highly efficient in all operative conditions suitable for automotive application. 

The nature and mobility of ions and solvent in zeolite cages will affect the ac-impedance of the material. This effect can be utilized for zeolite-based sensor concepts where a zeolite film is coated on interdigitated electrodes. For example, it was shown that the impedance of a film of proton-conducting H-ZSM-5 is influenced by the presence of ammonia (Figs. 15, 16).[126,127] The ammonia is protonated in the zeolite, thus producing much larger ammonium ions with different mobilities in the zeolite that can be detected by impedance spectroscopy. The detection of ammonia is of interest for automotive applications where the selective catalytic reduction of NOx by ammonia is envisioned. 

This is not to say that price is the sole criterion by which batteries are selected in automotive applications where benefit can be realized through either reduced weight, improved life, lower maintenance, less gassing, or increased reliability, the choice may be logically made to use VRLA in lieu of the flooded equivalent. 

EPDM tends to show good resistance to ozone attack, oxidation resistance, and moisture resistance. It is therefore used in applications that require good weather resistance and heat stability. Roofing materials, outer covers of high-voltage electric cables, and selected automotive hoses use EPDM. 

In view of the above efforts, it is surprising that the majority of recent patents on adhesives are for solvent-based systems.The new inventions include a universal primer, an adhesive composition in which solvents have been selected based on Snyder s polarity (only solvents which belong to group III are useful in adhesive for automotive applications to avoid a deleterious effect on paint), a low VOC adhesive for pipes and fittings, a solvent-containing heat-resistant adhesive based on siloxane polyimide, a water-based polyimide adhesive,and two-component solvent-free polyurethane adhesive system for use in automotive door paneling. ... 

A major factor in the selection of elastomers for automotive applications is the extent to which they absorb petrol or oil. When an elastomer absorbs diluent (vapour or liquid) it is said to swell (this is illustrated in Figure 3.12). The increase in volume shown is X4. The increase in length of any... 

In addition, the structure of the uncured materials can be selected to fit a variety of industrial application processes. Thus, they are used in Aerospace applications, Automotive applications, as Adhesives in the textile industry and in building, electronic, healthcare, energy, medical, paper and personal care industries (see Adhesion in medicine). 

Particularly in automotive applications, the design engineer selects materials that will endure periodic fluctuations of both tensile and flexural type loads for the service lifetime of the molded part. Under-the-hood automotive conditions include extremes in ambient temperature combined with possible localized vibrations from the engine and rotation of molded parts (cooling fans) under continuous load. Although deformation will occur due to creep, there is concern regarding fatigue type failure after repeated fluctuations of the applied load.
