Wire & Cable

KetaSpire® PEEK

KetaSpire® PEEK is a semi-crystalline thermoplastic with excellent mechanical and chemical resistance properties. It provides exceptional performance over a wide range of temperatures and extreme conditions, has very good electrical properties and provides a unique range of high-performance properties in Wire & Cable applications.

Typical properties

  • Continuous service up to 240 °C
  • Good electrical performance
  • Low smoke and toxic gas emission
  • Excellent wear resistance
  • Mechanical strength and dimensional stability
  • Long-term thermal oxidative stability (UL Relative Thermal Index) up to 240 °C
  • Broad chemical resistance and low permeation to chemicals

Solvay Wire & Cable solutions can be specified for applications demanding superior physical performance such as improved flexibility, flex-fatigue performance, fire properties, good abrasion resistance and chemical performance across broad temperature range. All our materials are RoHS compliant and as such lead, plasticizer and halogen free.

KetaSpire® KT-851 PEEK

KetaSpire® KT-851 resin is a deep-filtered grade of PEEK specifically designed for continuous extrusion processes and can be used to manufacture thin insulation coatings onto copper or other conducting wires. It offers outstanding chemical resistance, excellent wear resistance and higher operating temperature range (continuous 240 ºC) and possesses outstanding flame retardant and low smoke emissions properties.

The LOI (Limiting Oxygen Index) is 35% and even when burning the material has very low smoke generation. For example, wires and cables used in mass transit systems (rolling stock) and aerospace industries must have extremely low flammability and smoke emission to reduce the hazard to passengers and crew in the event of a fire. Independent testing has shown that KetaSpire® KT-851 has a UL94 rating of V-0 and samples show no appreciable smoke emission after ignition.

Typical applications

  • Military specification cables
  • High temperature cables
  • Harsh environment cables for extreme cold and/or heat
  • Control and instrumentation cables
  • Thermocouple wire (Nuclear Power Plant)
  • Magnet wire

AvaSpire® PAEK

AvaSpire® PAEK resins provide a new and unique combination of performance and attractive economics. Cable designers are able to specify AvaSpire® PAEK materials in specific applications or in cases were PEEK may be over-engineered to bridge price and performance characteristics.

The specific grade AV-630 PAEK is well suited for Wire & Cable applications and can be used for ultra thin film thickness (5 microns).

AvaSpire® PAEK provides similar property profile to PEEK with advantages in ductility, improved flexibility and heat resistance performance. It can be used for niche applications where high temperature, chemical and mechanical performance are required and within target markets such as Rail, Marine, Nuclear and Aerospace. Wires and cables made of PAEK products retain toughness and show good handling characteristics with improved economical manufacture with respect to PEEK.

Typical properties

  • Improved flexibility over PEEK
  • Improved toughness over PEEK
  • Higher heat deflection temperature
  • More attractive economics
  • Processed using conventional processing equipment

The thermal performance characteristics and melt stability of PAEK materials allow for ease of processing for Wire & Cable applications and permit high end-use temperatures for long periods of time.
