Polyamide-imides (PAI) Sheet is either thermosetting or thermoplastic, amorphous polymers that have exceptional mechanical, thermal and chemical resistant properties. Polyamide-imides are used extensively as wire coatings in making magnet wire. They are prepared from isocyanates and TMA (trimellic acid-anhydride) in n-methyl-2-pyrrolidone (NMP).Polyamide-imides display a combination of properties from both polyamides and polyimides, such as high strength, melt processibility, exceptional high heat capability, and broad chemical resistance

Remark:
1. Tolerance is according to DIN Length: 0~3 %, width: 0~ 3%.
2. it is theoretical value for above spec, with the 1000 x 1000 mm, also we can supply 610x 1220mm, 1000x 2000mm
3. Taking objective as standard, listed data are for reference only.
4. The products above have been strictly treated with tempering; the strain value has met the minimum.

PAI Feature
  • Very high maximum allowable service temperature in air (250°C continuously)
  • Excellent retention of mechanical strength, stiffness and creep resistance over a wide range of temperatures
  • Extremely low coefficient of linear thermal expansion up to 250°C
  • Excellent wear and frictional behaviour (particularly Duratron 4301 PAI)
  • Inherent low flammability
  • Exceptional resistance against high energy radiation (gamma & X-rays)
  • Excellent UV-resistance
