POLYAMIDIMID

Polyamideimide (PAI), widely known as the 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.

APPLICATION

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

PAI SEMI-FINISHED

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.
