Why use Torlon?...

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.

With a 280°C and more heat distortion temperature (softening temperature) and a 200 - 220 °C continuous service temperature(UL RTI), Torlon offers unmatched strength at elevated temperatures. It is better at 200°C than any other engineering resin at room temperature. Torlon is also tougher and more impact resistant at cryogenic temperatures than other high strength polymers.

Why should I use PEEK?

PEEK is recognized as having the best balance of chemical resistance, wear resistance and heat resistance among all thermoplastics. It is melt processible allowing for processing into shapes by extrusion and parts by injection molding.

Technically PEEK is part of a family of polyarylether ketones (PAEK) but the PEEK acronym is most recognized. Related chemistries based on PEK and PEKK offer unique thermal benefits to the traditional PAEK’s.

... or preferably AvaSpire PAEK?

AvaSpire polyaryletherketone (PAEK) is a PEEK-based polymer blend with a notably higher Tg than PEEK at 158°C. Depending on the chemical environment and stress load, its greater ductility and its stiffness over 150°C can make it an attractive alternative to PEEK. The unreinforced grade’s light color also enhances part aesthetics and colorability.

AvaSpire is FDA compliant in all grades including the carbon and glass-reinforced formulations that provide higher mechanical strength over the unfilled material.

Ryton R-4 has a Tg of 88°C and delivers impressive mechanical strength, electrical insulation, and exceptional chemical and hot water resistance. In fact, it has no known solvents below 200°C. Its performance and cost make it an excellent choice for applications in aggressive chemicals at elevated temperatures.



Previously limited to injection molded parts, Drake’s development of Ryton R4 stock shapes has led to its expanded use in precision-machined electrical, fluid handling, transportation and oil and gas equipment components.

Why Drake Plastics?

Drake Plastics leads the industry in ultra-high-performance polymers with the widest array of rod, plate, and rigid tube stock shapes for machined parts. Many sizes were developed to closely approximate the dimensions of a final part. The benefit of these “leaner” sizes: minimal material loss when machining our line-up of Torlon PAI, PEEK, Ryton PPS, Victrex HT, Ultem PEI and AvaSpire PAEK stock shape products.

Product and process development investments coupled with our culture of invention have yielded sizes and configurations many thought impossible in ultra-high-performance polymers.

With more than 25 years’ experience in our field, engineers often consult with us to determine the best material for their applications. Once specified, they know our products will perform consistently through their application’s life cycle, thanks to our rigorous AS9100D/ISO9001 Quality Management System and unique process control technology. In addition, our in-house machining and injection molding operations afford hybrid molded/machined parts when needed for precision tolerances and allow an easy transition from machined to molded parts.

On service, Drake’s on-time delivery is typically 98% or better, and 100% customer satisfaction is the norm. Our friendly and knowledgeable team look forward to adding you to our long list of happy customers.
