Amber Polyethyleneimine Textured Pei Sheet
polyetherimide sheet, which is a non-crystalline plastic. It is an amorphous high-performance polymer. It is made of engineering plastics made of amorphous PEI (polyetherimide) and extruded at high temperature through an extruder. The commonly used PEI board is made of American GE raw materials (trade name Ultem).
Features
1. The maximum allowable working temperature in the air is relatively high (continuous working temperature 170℃)
2. Excellent hydrolysis resistance (suitable for repeated steam sterilization)
3. In a wide temperature range, good mechanical strength and high rigidity
4. Inherent low flammability and less smoke during combustion
5. Good dimensional stability
6. Physiologically inert (suitable for contact with food)
7. Resistance to high-energy radiation (r-ray and X-ray)
8. Good electrical insulation performance
Application:
1. Steam cleaning equipment, electrical components
2. Electrical and electronic equipment parts, auto parts, connectors
3. Aerospace, aviation, automotive interior parts, electroplating process equipment
4. Semiconductor manufacturing, equipment parts, glass parts manufacturing plants
