PTFE Socket Head Screws

Polytetrafluoroethylene (Polytetrafluoroethylene, abbreviated as PTFE), commonly known as "Plastic King," is a tetrafluoroethylene as a monomer polymerization of polymers; the chemical formula is (C2F4)n, heat resistance, cold resistance is excellent, can be used for a long time in the -180 ~ 260ºC. Use.

1. Anti-corrosion: PTFE Socket Head Screws have been widely used in petroleum, textile, and many other industries due to their outstanding corrosion resistance. The representative ones include exhaust, steam, high and low-pressure valves, and other fastening connections. Especially in conventional materials that can not be used in low temperatures, anti-adhesive, and other harsh environmental conditions, more reflective PTFE Socket Head Screws have the advantage.

2. electrical and electronic: PTFE has a relatively small dielectric constant, so it can be used to prepare enameled wire, which can be used in micro-motors. In addition, fluoroplastic film has a specific selective permeability to various gases, so this feature can be utilized to prepare oxygen sensors. Nowadays, many forms of PTFE Socket Head Screws play an essential role in the field of electrical and electronic insulation. PTFE glass enameled cloth and glass cloth are used to make high-temperature and high-frequency insulation materials, which can be used in satellite communications and computers and other aspects of the fastening connection; PTFE film is used to make capacitors as an insulating layer between the instrument gaskets, cables, etc.; PTFE thin-walled tubes of different caliber are used for the preparation of enameled wires, which can be used in micro-motors. PTFE thin-walled tubes were used for lead wire casing, heat shrink and spiral tubes, generator insulation lead pipe, etc.

3. in medical treatment: PTFE's excellent biocompatibility has helped many people as a biological material for in-depth research in recent years. In recent years, domestic and foreign development of PTFE membranes used as artificial organs, such as artificial blood vessels, heart valves, etc.; for example, in the clinic will be PTFE Socket Head Screws as artificial blood vessels, rhinoplasty in the prosthetic stent material tightening Connection, have achieved good results.

4. low friction performance in the load: because of its relatively low coefficient of friction compared with most solid materials, filled PTFE has gradually evolved into all kinds of parts of the oil-free lubrication of the excellent material. PTFE Socket Head Screws are used in an extensive range of applications, including bearings of chemical equipment, piston rings, steel structure roof support slider, as well as bridges, such as the role of the tightening of the rotating body.
