| About |
|---|
| Torlon® 7130 is an 30% carbon-fiber reinforced grade of polyamide-imide (PAI) resin. It offers high strength and modulus, exceptional creep resistance, and good fatigue resistance. It has thermal expansion characteristics similar to steel, and therefore excellent dimensional stability. Torlon® PAI has the highest strength and stiffness of any thermoplastic up to 275°C (525°F). It has outstanding resistance to wear, creep, and chemicals. The potential applications for this resin include metal replacement, sliding vanes, aerospace parts, impellors, shrouds, pistons, and housings. It is available in injection molding and extrusion (E) grades.&& |

| 1. Typical properties: these are not to be construed as specifications. |
| 2. ASTM Test Method D1708 has been used to measure the tensile properties of PAI and similar materials because the small test specimen conserved material. Today the most widely used specimen is the Type 1 bar of ASTM D638. These D1708 values are included for historical purposes and they should not be compared to the D638 values. |
