PEI
PEI or ULTEM™ has excellent strength, thermal stability, and meets FAR 25.853 and OSU 65/65 with low toxicity, smoke, and flame evolution.
ULTEM technical description:
Tensile Modulus: 2.15 GPa
PEEK
PEEK is as strong as metal and has excellent mechanical and thermal resistance up to 260 °C. This organic polymer is resistant to dissolving in oils and other substances, unlike most other plastics.
PEEK technical description:
Tensile Modulus: 4.0 GPa
PPSU
PPSU is a high-temperature, chemical-resistant polymer that provides a lower cost alternative to PEEK and ULTEM.
PPSU technical description:
Tensile Modulus: 2.1 GPa
PEEK MATERIAL
PEEK (poly-ether-ether-ketone) is a high strength, temperature resistant, chemically resistant, inert thermoplastic used in various engineering applications, from aerospace and medical. It is also used as a lightweight substitute to replace metals parts for mass reduction.
Orion AM's patent-pending Thermal Radiation Heating technology helps get the most benefit from these material properties by increasing interlayer bonding and crystallinity. This results high strength parts for end-use applications.
