Polytetrafluoroethylene (PTFE), commonly known as Teflon, is a special pipe made of materials that are extruded and sintered, dried, high-temperature sintered, and formed. It is widely used in important science and technology industries such as machinery, electronic appliances, automobiles, aerospace, chemical industry, computers, electric heating, military, and communications.

Nylon was developed by the outstanding American scientist Rothers and a scientific research team led by him. The emergence of nylon has brought a new look to textiles. Its synthesis is an important part of the synthetic fiber industry. This breakthrough is also an important milestone in polymer chemistry.

The density of PTFE is generally greater than 2, while the density of nylon is around 1.2. The density of PTFE is relatively dense, high temperature resistance and hardness are better, while the nylon tube is softer, and the high temperature resistance is worse than that of PTFE tube, but because it is relatively soft, it can adapt to more terrain. In terms of price, PTFE tube is slightly higher than nylon tube.
