Ignition cables

Bayer, USI, and DuPont are U.S. suppHers. There is an estimated 2300—4000 t/yr of EVA used in the United States. Uses include automotive electrical system components, eg, ignition cable, footwear, weatherstripping, and misceUaneous O-rings and seals for industrial appHcations. 

Auto uses are said to account for about one-third of the 30000 tonnes of silicone rubber consumed annually around the world (in turn about 10% of total silicone consumption). Specific uses include shaft sealing rings, spark plug caps, O-rings (the major market for the fluorosilicones), gaskets, coolant and heater hoses for buses and trucks, and ignition cables. 

Objective 4. Demonstrate the ability of grinding equipment to safely process foreign objects such as detached antiresonance rods and igniter cables. 

Uses of silicone rubbers car uses (sealing rings, O-rings, gaskets, ignition cables etc.), cable insulations. 

In the manufacture of many automobile parts, including air bags, gaskets, headlamps, hydraulic bearings, ignition cables, radiator seals and hoses, shock absorbers, spark plug boots and ventilation flaps ... 

Related to arc resistance is ozone resistance. This gas is found in the atmosphere around high-voltage equipment. Ignition cable insulation, for example, should be ozone resistant. Natural rubber is easily attacked and deteriorated by ozone. Fortunately, most synthetic resins have good ozone resistance and are satisfactory from this point of view. 

Liquid silicone rubbers have also been used in some extruded applications. Vulcanization of the extruded material may be carried out by using infrared heaters or circulated hot air. The process has been applied to wire coating, ignition cables, optical fibers, various tapes, and braided glass-fiber sleeving, as well as for covering delicate products.

Ethylene-propylene rubber finds application in the electrical industry and in the manufacture of electrical equipment. One of the primary applications is as an insulating material. It is used for medium-voltage (up to 35 kV) and secondary network power cable, coverings for line and multiplex distribution wire, jacketing and insulation for types S and SJ flexible cords, and insulation for automotive ignition cable.

Silicone elastomers are used in the antomotive indnstry in snch applications as ignition cables, coolant and heater hoses, O-rings, and seals. In aircraft applications, they are used in seals, connectors, cnshions, and hoses, fir home applications, they are used in O-rings, seals, and gaskets. There are also uses in naval and other applications. 

The main advantages of PP over PE in the automotive industry are its higher temperature resistance and better mechanical properties of nonhalogen flame resistant formulations. Therefore, the use of PP in the under-hood applications is common. The automotive industry wants to move away from PVC. Typically, the automobile ignition cables are made of EPDM or TPO. 

Connector seals Crank shaft seals Exhaust pipe hangers Ignition cables Membranes... 

A typical application is ignition cables where some automobile manufacturers specify an adhesion force of 70 N per 5 cm of ignition cable. This type of specification has been setup to assure proper adhesion when the ignition cable is disconnected from the spark plug. 

Applications acid storage tanks, cables, capacitor films, filtration, fuel seals, heating cables for car seats, ignition cable, membranes, reactive liner of warheads, tubing, valves ...

In addition, approx. 160,000 cars annually are damaged by martens. This so-called bite damage to ignition cables, coolant hoses, transmission and steering collars, and insulation materials annually costs approx. 20 million Euros. Under the hood is a fine place for a marten to hide, a good place to warm up in cold weather. Martens instinctively use their teeth to test the texture of objects. When the marten smells a rival, he goes into a destructive frenzy, and nothing is safe from his sharp teeth. 

Spark plug boots and ignition cables are used by the majority of the world s car producers, particularly in the USA where an all-silicone cable harness is commonplace.
