For example, at a thickness of 0.75 mm, the material has a TRI (Relative Thermal Index) of 300°C according to UL 746B. Thanks to its continuous service temperature of 300°C, ECCtreme™ ECA exceeds the previous upper limit of 260°C for conventional perfluoroplastic insulating materials.
ECCtreme™ ECA grades can be processed on conventional high-temperature fluoroplastic extrusion equipment using standard processing conditions. Downstream heat treatment (epitaxial co-crystallization) improves the material's thermal strength and provides beneficial mechanical properties, such as long-range tensile modulus and enhanced crack stress resistance.
The material is suitable for insulating wires and cables exposed to extreme service conditions such as very high temperatures, high pressures, and corrosive environments. Typical applications include the oil and gas industry, aerospace, power generation, semiconductor manufacturing, and the automotive industry.
Other products showcased include Teflon™ fluoroplastic foam (FFR) resins produced using patented Airquick technology. Cables made with fluoroplastic foam insulation have lower signal return loss than conventional data cables, enabling miniaturization and weight savings through lower density and thinner insulation thicknesses. A current example is the new KL24 Star-Quad data cable developed for the aerospace industry by Draka FILECA, Sainte-Geneviève, France. At the same diameter, it is up to 25 percent lighter than previously used quadruple cables, allowing for reduced aviation fuel consumption and thus lessening environmental impact.
