PTFE
PTFE, commonly known as "plastic King" is the best engineering plastics in the world. It has an excellent chemical stability, corrosion resistance, self-lubricating without viscosity, flexible and electrical insulation and anti-aging ability. It worked for a long time under the tempreture -60º C~+250º C. In the chemical industry, machinery, electronics, electrical appliances, military, aerospace and other fields are widely used.
