Torlon 4501 PAI
This compression moulded material is similar in composition to TORLON 4301 PAI, and is selected when larger shapes are required.
Profile
- Very high maximum allowable service temperature in air (250°C continuously)
- Excellent retention of mechanical strength and stiffness over a wide temperature range
- Extremely low coefficient of linear thermal expansion up to 250°C
- Excellent wear & frictional behaviour (particulary TORLON 4301 PAI)
- Outstanding UV-resistance
- Inherent low flammability
- Exceptional resistance against high energy radiation (gamma and X-rays)
Applications
- Chip nests and sockets
- TORLON 5530 PAI nests and sockets are used during the testing of chips. By retaining dimensional stability over a broad temperature range, parts made of TORLON 5530 PAI improve reliability of test connections and extend part life.
- High temperature electrical connectors
- TORLON 4203 polyamide-imides provide outstanding electrical performance and high temperature stability.
- Labyrinth seals
- TORLON 4503 PAI's rub tolerance gives users and manufacturers of turbocompressors efficiency gains and higher throughput capability by reducing seal clearances.
- Bearing cages
- TORLON 4301 PAI's low expansion rate and excellent wear resistance enable manufacturers to increase bearing speeds and extend part life.
- Can mandrels
- These mandrels made of TORLON 4203 PAI support aluminium cans during printing. Having an excellent dimensional stability as well as high wear and abrasion resistance, these mandrels exhibit a longer part life at increased production rates. TORLON 4203 PAI's extraordinary compressive strength and abrasion resistance permit higher production rates, longer part life, and increased support of aluminium cans during printing.
- Rotary compressor vanes
- More efficient operation and more reliable long-term performance make TORLON 4301 PAI the optimum material for sliding vanes in rotary compressors. The material's high stiffness and excellent dimensional stability even at elevated temperatures, enable the vanes to travel freely in and out of the slotted rotor without binding.
- Beaker welding supports
- These TORLON 4301 PAI supports are used in food packaging machines for sealing plastic yoghurt cups with an aluminium foil. These supports are subjected to high wear and abrasion at temperatures going up to 200°C.
