Polyamide-imide (PAI) Sheets
Polyamide-imide (PAI) sheets exhibit exceptional mechanical strength and hardness, even in extreme temperature conditions. These PAI polymer sheets maintain their structural integrity at elevated temperatures, boasting a remarkable temperature stability during molding processes and a high glass transition temperature of +280°C.
PAI materials retain their integrity and functionality even at the most demanding operational temperatures, ensuring flawless performance under extreme heat conditions.
Polyamide-imide (PAI) finds application in various industries, including:
- Gearbox production, where it is used for manufacturing moving parts, track rollers, bearings, gears, and bearing washers (axial bearings). It’s also utilized in hydraulic controllers and balls production.
- In a range of components such as bushings, vanes, seals, jacks, panels, electrical elements, gears, plugs, connectors, pneumatic and hydraulic pump parts, seals, valves, and cryogenic technology components.
- PAI is employed in the manufacturing of furnace components, conveyor items, hydraulic valves, air grilles, and security features. It excels in applications like clutch seals, bearings, and sliding bearing components, providing exceptional strength and stability.
Polyamide-imide (PAI) can also be reinforced with glass for enhanced quality and stability.
PAI, or polyamide-imide, is the material of choice for runners and guide rollers in paper handling equipment, such as printers, copiers, and office machinery.
Additionally, it is used in details, plugs, and test sockets for microelectronic chip testing and lamp holders in the microelectronic industry.
