Polyamideimide (PAI), widely known as the brand Torlon® comes in different grades and different shapes. PAI is known to be the highest performing meltable thermoplastic in terms of temperature resistance, chemical resistance and mechanical strength. Its mechanical strength at 205°C outperforms many engineering plastics at room temperature. The unique performance of polyamideimide (PAI) is the result of being transformed from a thermoplastic to a cross-linked thermoset during an extended curing process. Our PAI is processed by experienced engineers and offers the excellent mechanical properties and high purity.
PAI can be used for: gears, rollers, plasma chamber hardware, wafer contact fixtures; high-temperature thermal/electrical insulators, burn-in/test sockets, valve seats, fasteners and activation balls; mechanical linkages, labyrinth seals, impellors, valve plates, vanes, back-up seal rings
Our PAI semi-finished products are extruded and cured/heat-treated. We offer custom made sizes, and stock shapes. Our stock shapes are rods and plates. However, tubes and special shapes are available upon request.
We offer PAI Semi finished products made of Dexnyl© PAI GF30, a high modulus polyamideimide containing 30% glass fibers, well suited for electrical insulators and thermal isolators. Dexnyl© PAI GF30 is ideal for: High temperature thermal/electrical insulators / Test sockets for IC’s / Fasteners / Activation balls and valve seats. Each type is best suitable for a specific application. Please contact us for more information.
