Flexx-Sil Jacketing

flat cables more flexible with Flexx-Sil jacketing

Flexx-Sil Makes Flat Cables Simply Superior

Cicoil invented the ribbon cable in 1956, and we have continually perfected and improved our technology to make high performance flat cables. After years of extensive R&D, Cicoil achieved a breakthrough in the method and materials used in making our flexible flat cables. In combination with our patented extrusion process, Cicoil developed an exclusive material which is ideally suited to high flex, high performance flat cable applications. This unique material is called Flexx-Sil™, and it combines the best aspects of the silicone rubber polymer with our exclusive extrusion process, to make the most advanced cable jacketing material available in the marketplace.

Flexx-Sil™ cable jacketing provides the following high performance features:

  • Temperature Extremes – Operates at temperatures from -65°C to +260°C. Also stays flexible in temps as low as -100°C.
  • Flexibility – Has the natural flexibility of silicone rubber, which is more than twice as flexible as PVC or PTFE insulation.
  • Crystal Clear – Flexx-Sil™ is crystal clear, and virtually translucent, clearly showing the purity and the cleanliness of the material.
  • Low Outgassing – The purity of Flexx-Sil™ means that it has very low outgassing characteristics, as the molecular bond is extremely strong, and the extrusion process results in virtually zero impurities.
  • Durable – Flexx-Sil™ has a Durometer of 65 (Shore A), and can be provided in a SuperTuff™ version with a Durometer of 85 (Shore A).
  • Zero Particulates – The purity of Flexx-Sil™ results in a Class 1 Clean Room rating, as the insulation material has zero particulates
  • Halogen Free – Flexx-Sil™ jacketing is 100% Halogen Free
  • Water/Chemical/UV Resistant – Flexx-Sil™ jacketing is water proof (including immersion), is resistant to most chemicals, and can operate for years in intense UV and sunlight conditions.
