Spark plug boots

High elasticity is also not utilised in the main application of chlorosulphonated polyethylenes, in wire and cable coating, which consume about 40% of output. The combination of heat and oil resistance has led to widespread use as sheathing for nuclear power cables, offshore oil rig cables and in diesel electric locomotives. Other uses include chemical plant hose, spark plug boots and as a base for flexible magnetic strips. 

The main use for acrylates is in sealing applications where the improved heat stability over nitrile rubber is the benefit. Automotive transmission seals are probably the major use, other automotive applications include O-rings, hose, tubing, cable covering and spark plug boots. Also used in adhesive formulations. 

Additional curing is often achieved with sulfur, peroxide, or maleimide formulations. Chloro-sulfonated polyethylene has improved resistance to oil, ozone, and heat compared to many other elastomers. Applications include harrier membranes and liners, surface coatings on fabrics, automobile air-conditioner hose, electrical cable insulation, and spark-plug boots [Andrews and Dawson, 1986],... 

To demonstrate the actual savings realized by a fabricator, the energy required to mold a 9 gram spark plug boot by the LPS process and by the conventional process is compared. In this calculation, it is assumed that 100% acceptable parts are produced by both processes. In practice, the rejection rate of LPS is much lower than the conventional process. The results of calculation are summarized in Table II. The ratio of energy required by the LPS process to that of the conventional process is almost 1 4.

CSM compounds possess excellent resistance to ozone attack, oxidation, and weathering, even for nonblack products. Also, these CSM compounds usually possess some oil, water, and chemical resistance. Therefore, CSM compounds are used in environmental applications (especially pond linings), insulation for cables, spark plug boots, coated fabrics, hose covers, single-ply roofing, rafts, and folding kayaks. 

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.
