DRAKE 4200 PAI STOCK SHAPES CURRENTLY IN DEVELOPMENT
INTRODUCTION PLANNED 2022
Performance comparable to Torlon 4203L with no TiO2 pigmentation.
Drake 4200 PAI’s physical properties compare directly to those of Torlon 4203 PAI. The difference between the two materials is that the Torlon 4203 PAI formulation contains TiO2 which imparts a distinct yellow-gold color. Drake 4200 PAI is produced from Torlon 4000T powder which we convert into the pelletized form required for extrusion into shapes. It contains no TiO2 pigment. This resolves concerns about potential contamination from titanium in critical production processes where high purity is essential. An example is the plasma etching step in semiconductor manufacturing where ionic metallic impurities can affect the integrity of the nano-scale microcircuitss.
Its low erosion rate, broad thermal capability, strength under load and inherent toughness of Drake 4200 PAI exceed that of PEEK and polyimides over a broad temperature span, from cryogenic levels to 250°C/ 482°F. The overall property profile of Drake 4200 PAI also make it a frequent choice for load-bearing components and applications where thermal or electrical insulation and isolation are required.
Drake 4200 PAI typical applications
- Semiconductor wafer probes, chamber hardware and fixtures
- Plasma etch chamber wafer handling tools
- Reticle pins, electrical components
- Gears and rollers
Why Drake 4200 PAI Was Developed
Though infrequent, specific grades or forms of resins may be discontinued by suppliers. When this occurred with the PAI resin grade in pelletized form necessary for extruding Torlon 4200 shapes, Drake Plastics developed the technology to convert a powder form of the resin into the required pellet version. We now offer Drake 4200 PAI shapes as a direct replacement for those previously sold as Torlon 4200 PAI with no compromise in performance or quality.
Drake 4200 PAI Certifications and Traceability
As with all our products, we provide no-charge certifications and lot traceability on each shipment of Drake 4200 PAI shapes and machined and injection molded parts. We are investigating certifying Drake 4200 PAI to the requirements of AMS3670/1 and ASTM D5204.
