whytorlon-1 Torlon® polyamide imide is recognized as the highest performance thermoplastic that is still melt processible. Torlon® can be extruded into shapes and injection molded into custom geometries. Depending on the grade, Torlon PAI has a heat deflection temperature of up 282°C and affords unparalleled strength at high temperatures. It has been used in many applications with continuous exposure * to 260°C for extended periods and is stronger at 204°C than other engineering resins at room temperature. Torlon PAI is also tougher and more impact resistant at cryogenic temperatures than other high strength polymers.

* Please check "Continuous use temperature (CUT) performance" to know what you may expect in your application.

Its exceptional mechanical and thermal properties result from an extended curing process* that extends the PAI polymer chain and increases its molecular weight. Glass-reinforced and carbon fiber reinforced grades offer even greater stiffness plus enhanced thermal expansion properties.

*Drake Plastics cures all Torlon® products prior to shipment.

High Strength Torlon PAI


Drake PAI 4200 Non-reinforced

Drake PAI 4200 is Torlon 4000 T resin which has been compounded into pellets, making it suitable for extrusion or injection molding. Drake PAI 4200 is a temperature extreme capable, high purity and high-performance thermoplastic for parts requiring the performance of unreinforced PAI such as Torlon 4203L, but without the TiO2 which is considered a potential contaminant in some applications. It also has excellent fatigue resistance. It is dark brown in color.

Drake PAI 4200 is well suited for:

• Fasteners used within the plasma etch chamber
• Wafer handling contacts
• Electrical insulators

The physical properties of Drake PAI 4200 are like those of Torlon 4203. The Torlon 4203L formulation includes a few percent TiO2 as a pigment to make a distinctive yellow/gold color. Concerns about the release of TiO2 has long worried leading semiconductor chip manufacturers.

The utilization of Drake PAI 4200 alleviates the concern that titanium dioxide particles released during plasma etching may contaminate the nano-scale topography of today’s micro circuitry. Better resistance to plasma than PEEK and polyimides within the etching processes for computer chip manufacture.

Drake PAI 4200 is stronger and stiffer than PEEK and PI over a wide temperature range, as shown in the graph.

T4200 vs PEEK&PI

Torlon® 4203L PAI


Torlon 4203L - Stronger and Tougher than PEEK and polyimide from cryogenic to 275°C.

Torlon 4203 and Torlon 4203L are non-reinforced polyamide-imide. The “L” designates resin designed for injection molded shapes and parts. Extruded shapes are made from the highest viscosity Torlon 4203 resin resulting in improved toughness, impact strength and fatigue resistance over injection molded parts. Torlon 4203 is the toughest and most impact resistant of the Torlon grades making it the choice for highly loaded wheels, rollers and balls. It has excellent dielectric properties and is also the best thermal insulator.

Torlon 4203L is ideal for:

• Valve seats/seals requiring high strength and dimensional stability
• Rollers, wheels and balls
• Aerospace electrical components requiring high strength, heat resistance and low flammability
• Thermal and electrical insulators

Torlon® 5030


Torlon 5030 is a high modulus polyamide-imide containing 30% glass fibers and 1% of PTFE. It is well suited for electrical insulators and thermal isolators. It offers a 50% lower CLTE than non-reinforced Torlon 4203L. The tensile strength of 5030 is unmatched and the modulus second only to Torlon 7130.

Torlon 5030 is ideal for:

• High temperature thermal/electrical insulators
• Test sockets for IC’s
• Fasteners
• Activation balls and valve seats

Torlon® 7130 Torlon 7130 containing 30% of carbon fibers and 3% of PTFE.

It is recognized as the strongest and stiffest of polyamide-imide grades. Torlon 7130 also has the lowest CLTE which closely matches both aluminum and many advanced composites. The high surface hardness resulting from the carbon fiber results in good wear resistance in well lubricated service.

Torlon 7130 is commonly used for:

• Vacuum pump vanes
• Mechanical stand-offs and linkages
• Impellors, wear rings and guides
• Labyrinth seals
