Shengjun Plastic Tech. Co. Ltd.,

Shengjun Plastic is a key developer of leading advanced materials and specialize in solving application challenges. Innovation is our business as we focus on the research and development for Thermosetting Polyimide.

Our polyimide material is a range of non- melting high-temperature polyimides which are characterized by the following properties:
  • No melting point,high strength over a wide temperature range from –280 °C to +300 °C
  • Excellent friction and wear properties – even without lubrication
  • Excellent electrical insulation properties
  • High compressive and creep strength
  • High radiation resistance
  • High purity, low outgassing in vacuum
  • Minimal thermal expansion
  • Long-term thermal stability up to 300 °C ˌ excursions to 480°C
  • Good chemical resistance to acids, fats and solvents
  • Good cryogenic properties
  • Inherently flame resistant (UL 94 V0)
