KetaSpire® PEEK and AvaSpire® PAEK

Today more than ever, engineers are turning to advanced materials to help them recover and process crude oil and natural gas. The move toward deeper drilling and deep water offshore reserves means higher temperatures, higher pressures, and often an aggressive chemical environment. Ultra polymers combine thermal performance, exceptional strength and stiffness, wear resistance, extreme hardness, chemical resistance, inherent flame resistance, high retention of mechanical properties in sour environment, good resistance to rapid gas decompression.

KetaSpire® PEEK is an easy-to-mold semi-crystalline polymer offering excellent thermal stability up to 240°C in continuous use, best-in-class fatigue resistance, and outstanding resistance to organics, acids, and bases.

AvaSpire® PAEK is a family of proprietary formulations with unique advantages that bridge price and performance gaps. They offer improved toughness relative to PEEK, as well as higher mechanical performance between 150–240°C.

Typical applications:

  • Compressor rings and plates
  • Compressor poppets
  • Back-up seal rings
  • Electrical connectors
  • Labyrinth seals
  • Motor end plate
  • Bearings
  • Bushings
  • Stock shapes
  • Wear tapes for flexible risers

Torlon® PAI

Torlon® PAI combines exceptional strength temperatures up to 275°C with excellent resistance to creep, abrasion, wear and chemicals. It has low thermal expansion and high dielectric properties, and is cost-effective in comparison with machined thermosets.

Within the Oil & Gas industry Torlon® PAI is widely used in turbocompressors.

Typical properties of Torlon® PAI:

  • Strength without reinforcement
  • Toughness
  • Cryogenic properties
  • Low CLTE
