Torlon® 4203 PAI

Also see Duratron T4203 PAI

Electrical or High Strength Applications

Torlon® 4203 PAI (Polyamide-imide) offers excellent compressive strength and the highest elongation of the Torlon® grades. It also provides electrical insulation and exceptional impact strength. This grade is commonly used for electrical connectors and insulators due to its high dielectric strength. Torlon® 4203 has the capicity to operate at 500°F continuous service temperature which makes it ideal for structural components such as linkage and seal rings. Torlon® 4203 PAI is harder at 400°F than other engineered plastics. It’s also an excellent choice for wear applications involving impact loading and abrasive wear.

ISO 9001:2008 Certified

It has outstanding resistance to wear, creep, chemicals connectors, switches and relays. In addition Torlon 4203 polyamide-imide can be used in applications such as thrust washers, spline liner, valve seats, bushings, wear rings, cams and applications requiring strength at high temperature and resistance to wear.

  • High Flow: Torlon 4203 – HF
  • Low Flow: Torlon 4203 – LF

 

Application Overview

  • Proven Applications

    High Temperature Electrical Connectors

    Torlon 4203 PAI and Torlon 5030 PAI provide outstanding electrical performance and high temperature stability. (Prior materials: Nylon, Quadrant PPS, Duratron® PEI)

    Bearing Cages

    Torlon 4203 and 4301 PAI’s low expansion rate and excellent wear resistance enable manufacturers to increase bearing speeds and extend part life. (Prior materials: Steel Cages, Hardened Steel Balls, Bronze Bushings)
