PAI Torlon® Polyamide-Imide Rod Ø19.05×1220mm | High-Strength Engineering Plastic Bar

PAI Torlon® Polyamide-Imide Rod Ø19.05×1220mm | Solvay High-Performance Engineering Plastic

This Torlon® polyamide-imide (PAI) round bar is produced from Solvay Torlon® resin — the strongest and stiffest melt-processable thermoplastic available. With a tensile strength up to 186 MPa and a continuous service temperature of 220°C, Torlon rods are the material of choice for precision-machined components in the most demanding industrial environments.

Key Properties

• Highest Mechanical Strength: Tensile strength up to 186 MPa — highest among all melt-processable engineering plastics
• Temperature Resistance: Continuous service to 220°C; short-term peaks to 260°C without loss of structural integrity
• Dimensional Stability: Very low coefficient of thermal expansion; maintains tight tolerances across a wide temperature range
• Chemical Resistance: Resistant to most acids, bases, fuels, hydraulic fluids, and organic solvents
• Creep Resistance: Exceptional resistance to deformation under sustained loads at elevated temperatures
• Machinability: Superior CNC machinability — tight tolerances (±0.01mm) achievable with standard carbide tooling
• Wear Resistance: Excellent PV (pressure × velocity) performance; low friction coefficient

Typical Applications
