Spire® Ultra Polymers Product Family

AvaSpire® polyaryletherketones (PAEK) – Tailored to provide new and unique combinations of performance and value. AV-600 Series products deliver a range of distinctive performance attributes with some grades offering more attractive economics when compared to PEEK. The AV-700 Series products offer comparable performance to PEEK at up to 30% lower cost.

KetaSpire® polyetheretherketone (PEEK) – Easy-to-mold ultra polymer offering outstanding chemical resistance, HDT of 315ºC (599°F) and continuous-use temperature up to 240°C (464°F).

PrimoSpire® self-reinforced polyphenylene (SRP) – Among the world's stiffest, strongest unreinforced polymers with a remarkable combination of surface hardness, chemical resistance and inherent flame-retardant properties.

EpiSpire® high-temperature sulfone (HTS) – The highest heat-resistant, transparent amorphous thermoplastic with a Tg of 265°C (510°F).

Torlon® polyamide-imide (PAI) – Delivers the highest strength and stiffness of any thermoplastic up to 275°C (525°F) and exhibits superior resistance to chemicals, creep and wear.

Combination of Superlative Properties

• Highest thermal performance
• Exceptional strength and stiffness
• Outstanding wear resistance
• Extreme surface hardness
• Broad chemical resistance
• Inherent flame resistance

Spire® ultra polymers are used today more than ever in demanding aerospace, automotive, electronics, health-care, industrial and oil and gas applications. Components like bearings, bushings, and gears can last longer when made from Torlon®, KetaSpire®, and AvaSpire® resins. That's because these high performance plastics combine exceptional wear resistance with high strength, thermal and dimensional stability, as well as chemical resistance in both dry and lubricated environments.

These high performance plastics are also used throughout the semiconductor industry where dimensional stability, wear resistance, chemical resistance, and high temperature processing are required. High strength and stiffness plus long-life performance makes them an effective alternative to metal components in wafer handling, processing vessels, parts carriers, and IC test equipment sockets and handlers.
