FE plastics are fluoroplastics, which are an important category of plastics.

　　Fluoroplastie refers to plastics made of fluororesin. The main varieties are polytetrafluoroethylene, tetrafluoroethylene copolymer, tetrafluoroethylene hexafluoropropylene copolymer and chlorotrifluoroethylene copolymer.

　　PTFE is the main variety of fluoroplastics, which has excellent chemical stability, weather resistance, electrical insulation and flame retardancy, outstanding surface non-stickiness, extremely low friction coefficient and wide service temperature range. It can be used as wear-resistant, corrosion-resistant, sealing, insulating, anti-sticking and high and low temperature resistant materials, and is suitable for working in the temperature range of 80 ~ 250℃ for a long time.
