Torlon 4200 PAI is now Drake 4200 PAI
PAI without TiO2 for maximum inertness, toughness and fatigue resistance.
An equivalent to Torlon 4200 PAI, Drake 4200 PAI meets the same specifications for performance and quality. It is available as extruded rod, plate and Seamless Tube for machining, and injection molded parts.
Drake 4200 PAI is Torlon 4000T resin which has been compounded into pellets to make it suitable for extrusion and injection molding. Drake’s technology team developed the compounding capability for the material after the original polymer supplier discontinued offering pelletized Torlon 4200 PAI.
While it offers the exceptional strength and temperature resistance of unreinforced PAI grades such as Torlon 4203 PAI, Drake 4200 PAI couples its high performance with high purity, particularly important for many semiconductor manufacturing applications. Unlike Torlon 4203, it contains no TiO2. The additive is used to give Torlon 4203 its distinctive gold color. However, it is a potential contaminant in semicon processes such as plasma etching where its release can contaminate the nano-scale topography of today’s micro circuitry. High-purity Drake 4200 PAI alleviates this risk.
Drake 4200 PAI is ideal for:
- Hardware and fixtures used within semicon plasma etch chambers
- Semiconductor wafer contact fixtures
