Metric PTFE Slotted Flat Head Screws

1. Anti-corrosion: PTFE materials have been widely used in many industries, such as petroleum, textile, and so on, because of their outstanding corrosion resistance. This represents the exhaust, steam, high school, low-pressure piping, valves, etc. Especially in conventional materials, it can not be used in low temperatures, anti-sticking, and other relatively harsh environmental conditions, which is more reflective of the advantages PTFE has.

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 materials play an essential role in electrical and electronic insulation. PTFE glass enameled cloth and glass cloth are used to produce high-temperature and high-frequency insulating materials, which can be used in satellite communications and computers, etc.; PTFE film is used to make capacitors, as an insulating layer between the instruments, gaskets, cables, etc.; PTFE thin-walled tubes of different calibers are used for lead-in wire casing, heat-shrinkable tube and Spiral tube, generator insulation water pipe, etc.

3. In medical treatment: PTFE's excellent biocompatibility, many people in recent years as a biological material for in-depth research; in recent years, domestic and foreign development of PTFE film used as artificial organs, such as artificial blood vessels, heart valves, etc., for example, in the clinic as an artificial blood vessel, rhinoplasty in the prosthesis stent material, have achieved good results.

4. In construction: Through the ultra-fine glass fiber fabric coated with PTFE resin, the PTFE membrane is lightweight, high strength, fire retardant, self-cleaning, not affected by ultraviolet rays, fatigue resistance, resistance to distortion, aging resistance, long service life, with high light transmittance and very little heat absorption. Because of the invention of this cross-generation membrane material, the membrane structure building becomes a modernized permanent building.

5. Low friction performance in terms of load: Because of its relatively low coefficient of friction compared to the vast majority of solid materials, filled PTFE has gradually evolved into an excellent material for oil-free lubrication of all types of parts. Its use is very wide, including bearings of chemical equipment, piston rings, supporting sliders of steel structure roof frames, and bridging transits.
