Automotive Ignition Cable Solutions

High-temperature resistance.
Consistent, high quality.  
Color options.

Fabricate ignition cables and spark plug wires with high-temperature resistance and consistent, high quality. Insulate and protect with Silastic silicone rubber.


Fabricate ignition cables that beat the heat

With proven Silastic® brand silicone high-consistency rubber (HCR) elastomers, you can fabricate ignition cables that:  

  • Maintain their flexibility at continuous high temperatures above 200ºC (392ºF) -- temperatures organic rubber materials cannot match
  • Provide critical dielectric (electrical insulating) protection required for automotive high voltage cables
  • Resist oil and fuel

Make your products stand out

For aftermarket spark plug wire applications, Silastic elastomers can be pigmented to provide the distinctive colors your customers demand.

Manufacture your products with ease and efficiency

Extrusion coating of ignition cable offers fast processing and a smooth tack-free surface. Silastic HCR elastomers can be fed directly into an extruder without additional preparation.

Work with our experts and take advantage of our processing expertise to:  

  • Increase your line speed
  • Attain better quality consistency

Improve product reliability and performance


 

Manufacture ignition cable that:

  • Withstands continuous high temperatures
  • Electrically insulates and provides dielectric protection
  • Exclude moisture, dust, oil, and fuel from critical connections
  • Provide corona resistance

Specify the right elastomer

For high voltage ignition wire and spark plug cables, we recommend a high consistency rubber (HCR) elastomer with a durometer between 50 and 70 Shore A, which can withstand temperatures as high as 260º C (500º F) and is able to be easily continuous-fed into extruder for either CV or HAV cure systems.
