Polybenzimidazole (PBI) Sheet has exceptional thermal and chemical stability and does not readily ignite. Due to its high stability, polybenzimidazole is used to fabricate high-performance protective apparel such as firefighter’s gear, astronaut space suits, high temperature protective gloves, welders’ apparel and aircraft wall fabrics. PBI is a very appealing material to high-tech industries such as semiconductor, aircraft and aerospace due to its unique property profile.

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.

PBI Feature
  • Extremely high maximum allowable service temperature in air (310°C continuously, going up to 500°C for short periods of time)
  • 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
  • Inherent low flammability
  • Good electrical insulating and dielectric properties
  • Low out gassing in vacuum (dry material)
  • High purity level in terms of ionic contamination
  • Excellent resistance against high energy radiation (gamma & X-rays)
  • Duratron PBI (Celazole PBI) Technical Notes
