DOCAPAI product family features

PAI (polyamide imide, polyamide imide or polyamide imide) is a high-performance plastic (HPM) with special mechanical properties. The Torlon brand name was introduced to the market by Solvay, Belgium. Its exceptional abrasion resistance, extremely low thermal expansion, exceptional dimensional stability even at high temperatures (up to 270°C) make it capable of withstanding extreme conditions. Its tensile strength is better than that of e.g. stainless steel or aluminium alloys. It has excellent chemical resistance, sliding properties, electrical insulation and high rigidity. Available in bar and plate formats.

Some important features

Excellent heat resistance, thermal stability in air
Good mechanical strength over a very wide temperature range
Excellent tribological properties (especially for some composite grades), very good impact resistance
Excellent dimensional stability up to 250°C
Outstanding resistance to Gamma and X-ray radiation
Highly flammable
Good UV resistance
Good machinability

Main areas of application

Natural Torlon PAI (4203) has the highest toughness and impact resistance of all PAI grades. As such, it is widely used in a wide range of temperature applications for device components and insulating parts in the semiconductor and microelectronics industries.
In friction applications, a PTFE (Teflon) and graphite doped composite version is used (Torlon PAI 4301). Widely used as a self-lubricating plain bearing material at high temperatures with improved sliding and wear resistance characteristics.
For increased dimensional stability requirements (e.g. at high temperatures, sustained static loading with minimum deformation), the glass fibre reinforced composite version (PAI 5530) can be used.

Machining technology

Chipping (turning, milling, drilling, sawing): carbide and diamond tools should be used. Cooling is recommended, with cutting speeds as follows: e.g. v = 250-500 m/min for turning and milling, v = 10-30 m/min for drilling.

Gluing: feasible.
